FUNCTIONAL DESCRIPTION

The RACOM 2816P Dialed Number Recorder evolved from the Racom 2800 and 2805 Dialed Digit Printers. The RACOM 2816P is a one line
portable version of the RACOM 2816 Multi-line Dialed Digit Printer. The 2816P contains the latest state-of-the-art microprocessor circuitry with plug-in circuit boards.
ifljnp^
The RACOM 2816P Dialed Number Recorder can easily be connected to most telephone lines by its modular connector to provide a printed record of the following:

1. Each telephone number dialed (up to 32 digits).

2. The date and time of the call.

3. The elapsed time of the call.

4. Whether the call was made from a rotary dial or a touch

ff|

tone telephone.

5. How long an incoming call rang and if it was answered.

6. The origination date and time of the incoming calls.

7. The elapsed time of the incoming calls.

8. Control and status of a cassette recorder.

9. The number that is calling when Caller Number Deliver is provided on the telephone line.

The 2816P has connections for two cassette recorders and a headphone. It can be connected directly across the telephone line or it may be used with a remote loop extender, such as the Racom Model LP2816.
The information can also be displayed on the RACOM 2816Ps LCD display.
The 2816P has an optional RS232 data output which can hold up to 750 calls waiting to be sent out through the RS232 data output.
Once connected properly to a telephone line, the RACOM 2816P is fully automatic and requires a minimum amount of attention. The only normal operating maintenance required is changing the paper and inked ribbon.

OPERATION

PfS
- 3 -

After the unit is in place and the proper telephone line connections
have been made, the printer is ready for normal operation. As each call is placed, you will notice the "line active" LED lights up for the line in use, indicating a call is in progress. While the RACOM 2816 registers all of the dialed information at the origination of the call, it does not print the data until the call has been terminated.

The following examples will describe four (4) common call transactions:

RECORDINGANDAUDIO MONITORING

The Racom 2816P has connectors for two cassette recorders and a audio monitor jack. Audio is on the miniature connecters (1/8 inch diameter). The subminiature connecters (Marked motor) connect to the remote jack on the recorders and they enable the recorder's motor to run under control of the 2816P. The 2816's printout indicates what calls (or parts of calls) are recorded. The recorder and audio circuits are toggled on and off automatically with telephone usage or they may be controlled manually from the keyboard.
To turn the audio and recorder on and off, put the LCD in the line display mode by pressing the "1" key. The recorder and the audio monitor may now be toggled with the "B" key. When it is toggled an "R" or an "0" will appear on the LCD. "R" indicates that the unit will record and "0" indicates that the recorder is off.
When the line being monitored is in use (active), toggling the recorder will cause a printout to occur. The right side of the paper shows two letters (R or 0), the first letter (to the left) shows recorder status before the change and the second letter (closest to the edge) shows the new status.
When the telephone is hung up, only one letter is printed. This shows the record's status at the end of the call.
When the telephone is on-hook the recorder is always off. However, what the recorder does when the telephone goes off-hook may be changed with the "B" key and is controlled by a variable called "Rec". See the software set section for more information on this.

LOOP EXTENDER RECEIVER

The Racom 2816P has a receiver for a remote loop extender. This

allows the 2816P to receive signals from a remote dual tone loop

extender or slave, such as the RACOM Model LP2816. The tone

frequencies are 852 Hz and 1633 Hz. The receiver is enabled when the mode switch is in the REMOTE position.

The 2816 may be ordered with other tone frequencies or for signal tone operation.

An optional 48 Volt power supply (Option F) can be used to power the

remote loop extender. The power supply and the remote receiver is

fcr^I

enabled when the mode switch is in the REM0TE/48V position.

- 9 pffiA
CALLER NUMBER DELIVERY (CND) Optional

The 2816P will print out the calling number when the telephone ^ company provides the service. The 2816P will print out the word j "From" and then the phone number to indicate the telephone number that is calling. The words "Privacy" and "Out of area" are also -- printed out as the telephone company sends them.

INKED RIBBON REPLACEMENT 1

The inked ribbon cartridge, located under the top panel of the printing unit, should be replaced approximately every four (4) rolls of paper, every six (6) months or whenever the printed numbers become difficult to read.

1. Swing open the panel over the printing mechanism.

SECTION TWO

This section deals with the RACOM 2816 from a more technical viewpoint than section one. Internal adjustments or modifications should be made only by technically qualified personnel.
CONFIGURATION

Before the RACOM 2816 is shipped, we carefully check out all

functions. We configure the unit so it will work on most phone

PPI

lines without reconfiguration. The RACOM 2816 is very versatile and

it has many uses. This section deals with the configuration and

setup of the RACOM 2816 to make it do particular things. The RACOM 2816 is configured in two ways. The first being with internal

switches and the second being with the setup of software parameters.

INTERNAL SWITCHES AND CONTROLS

ACCESS TO INTERNAL SWITCHES AND CONTROLS

The internal switches and controls discussed in this section are located behind the front panel. Access to these internal switches and controls can be gained by opening the small flap underneath the case.
Most switches have two positions - A or B. The switch is open in Position B and closed in Position A. A switch is in Position B when the rocker is flush with the front edge of the switch. Switches with toggle levers are in Position B when the toggle lever is toward the front.
Position A is when the flat or toggle lever is toward the rear of the switch.
HP9
DOUBLE OR SINGLE SPACE

The RACOM 2816 can either double space or single space between call transactions. Double spacing provides a clear separation between calls for transcribing.
PIPI
Section 7 of switch SW103 controls this feature.

TOUCH TONE AND DIAL PULSE EXCLUSION

All units are equipped with a feature that will shut down either the touch tone or rotary dial pulse decoders after the first digit of a number is decoded. If the digit is a touch tone digit, the rotary dial pulse decoder will be shut down. If the digit is pulsed, then the touch tone decoder will be shut down. This feature helps reduce falsing. SW103, Section 6 controls this feature. SW103 Section 6 Pos. A - No exclusion
Pos. B - Exclusion feature is enabled as described above.
PRINT LAST ROTARY DIALED DIGIT

Normally, a rotary dialed digit is entered into the RACOM 2816s memory after a valid amount of inter-digit time has elapsed. In some specialized applications, line current is reversed or removed before the inter-digit time has elapsed. So that the last digit is not lost in these applications, place SW103, Section 2 in Position A. Doing this will also result in the RACOM 2816s registering touch tone or rotary dialed digits that are received before line active time has been exceeded.
SW103 Section 2 Pos. A - Print first/last rotary dialed digit if it was not finished.
Pos. B - Normal

TOUCH TONEACCEPTANCE OR DROPOUT TIME

fwf

Touch tone acceptance is the time in which touch tone digits are accepted by the printer. The acceptance time begins when the line active LED lights and resets each time a touch tone digit is entered. After the acceptance time is exceeded, no more touch tone digits will be accepted until after the system has been restored to an "on-hook" condition. This feature is designed to prevent "falsing" caused by frequencies contained in speech.
The length of time is set by setting the variable "T Tone" to the desired time. Set "T Tone" to 255 for infinite touch tone acceptance time.

ppi

ipi

P^
ROTARY DIAL PULSES TIMEOUT

- 12 -

Thirty seconds after a call has been started, the rotary dial pulse w decoder for a line will be shut down. This is called rotary dial
pulse timeout and it is controlled by the variable "Pulse". To illuminate rotary dial pulse timeout, set the variable "Pulse" to 255.

r THRESHOLD ADJUSTMENT (R463)

The RACOM 2816 has a D. C. line voltage detector circuit in it.

This circuit detects if the phone is on or off the hook and decodes

rotary dial pulses. The telephone line voltage which causes the RACOM 2816 to recognize an off or on hook condition is called the

ip&J

threshold voltage.

m R463 should be adjusted so that this LED is illuminated when the phone is off the hook and off when the phone is on the hook.

p When the phone generates rotary dial pulse, this indicator should [ flash in sequence with the dial pulses. If it does not, then touch
up the adjustment of R463.
ipi
Note: Some exchanges may generate pulses on the line before or after rotary dial sequences. These will usually make this indicator LED flash. If this happens, R463 and dial pulse rate switch may be used to make the printer reject these pulses.

p?j

DIAL PULSE RATE SWITCH -

For each line in a RACOM 2816, there is a Dial Pulse Rate Switch. This switch selects the maximum dial pulse rate to be decoded by the RACOM 2816. This is Section 1 of Switch 401 on the line board. With the switch in position A, the maximum dial rate is 13 P.P.S. With the switch in position B, the maximum dial rate is 21 P.P.S.

INPUT INVERT SWITCH

i^S

For each line in a RACOM 2816, there is a switch that inverts the signal from the threshold detector. For normal operation, , the switch for a particular line should be in position B. Put the switch in position A to invert the input. This switch is Section1 4 of Switch 401 on the line board.

D. C. INPUT CONFIGURATION

Usually, the Racom Model RACOM 2816 Multiline Dialed Digit Printer is operating in a bridging mode. This means that the RACOM 2816s ^ high impedance inputs are connected across the telephone line.

The RACOM 2816 has separate A.C. and D.C. bridging inputs for each m line. Normally, for each line, these A.C. and D.C. inputs will be connected across the phone line for that line.

For bridging operation, these internal switches should be set as H follows on the appropriate line boards: J

SOFTWARE SETUP
pi

Many of the operating parameters for the RACOM 2816 are contained in the software. These parameters or variables are factory preset and stored in a memory chip called an EPROM. However, some parameters

may be changed to suit user requirements. These parameters are user programmable and are stored in a non-volatile memory chip called a NOVRAM. The working memory of the RACOM 2816 is in the CPU chip^

Upon power up or reset and approximately every two hours, the CPU

selects the operational parameters from either the EPROM or the

NOVRAM, depending on Switch 103 Section One (See Microprocessor Board section).

Microprocessor Board

Located inside the RACOM 2816 are two switches and a control on the

microprocessor board which selects the various operating characteristics of the RACOM 2816. One of these switches is a

sixteen position rotary switch (Ref: SW102) and the other is an

R5fj

eight section DIP switch (Ref: SW103). Switches are in the "open or

off" condition when placed in Position B. They are in the "closed or

on" condition when placed in Position A.

2816 MULTILINE DIALED DIGIT PRINTER
Option 4 - Data Output
With 64K Buffer
DESCRIPTION
This data output option is used to put data from the 2816 into a computer for further processing and analysis. The voltage levels are compatible with RS232 circuits.
The 64K buffer may hold data until the computer is available. The status of the data buffer is shown on the 2816's LCD display. Holding and sending of data may be accomplished with the 9 key on the 2816!s keypad, with X on - X off control codes on the RS232 link or with the DSR (Data Set Ready) pin on the back of the 2816.
This data output is intended to be connected to a computer so that the' data from it may be formated and then processed. For testing purposes, it may be connected to a nq terminal ·
Data is transmitted at 300 or 1200 baud, asynchronous, 7 bits, even parity and 1 stop bits.
The data from a call is transmitted when a call has been completed. After this data transmission, the 2816 will then print the data.
The data for each call is transmitted separately in an 87 byte ASCII coded sequence. The first byte is a dollar sign ($). It is followed by 84 bytes of data that contain all the information about the call. The 86th byte is a line feed. The 87th byte is a carriage return and indicates the end of the transmission.

DATA BUEFER. STATUS

The following words appear on the 2816,s LCD display and give the status of the Data Buffer as shown below.

WAIT The 2816 has been placed in the wait and hold data state.

Place it in this state with the 9 key on the 2816 fs keypad

or by sending an X off (Ctrl-S) to the 2816 over the

RS232 link. The buffer is presently empty. The word "HOLD11

Sfi

will appear as soon as there is data in the buffer.

HOLD The buffer is holding data. Data flow can be started by hitting the 9 key on the 2816 fs keypad or by sending an X on (Ctrl-Q) to the 2816. During hold, the DSR lead is high, indicating that the 2816 has data to send.
SEND The 2816 is sending data or may be trying to send data if the DTR (Data Terminal Ready) lead is not high.

CONNECTIONS

Rp
Connections for this data output option are provided on TB7 on the rear panel of
the 2816. Shown below are the definitions for these terminals. Also, the pin they
would connect to on a PC's 25 pin RS232 connector is shown.

TB7 Terminal 1 Ground (Signal Ground)

This is the ground and common connection. It must be connected to the receiving equipment. This connects to Pin 7 on the PC.

TB7 Terminal 2 RXD (Receive Data)

This is the terminal that data is received on. Use of this terminal ±s optional because the 2816 only processes the X on and X off control characters.
Connect this to Pin 2 of the PC. The PC can send an X off (Ctrl-S) when it wants the 2816 to hold data and an X on (Ctrl-Q) when the 2816 is sending data.

TB7 Terminal 3 TXD (Transmit Data)

This is the terminal that the 2816 transmits data on. It must be connected to the receiving equipment.
On a PC, it would connect to Pin 3.

TB7 Terminal 4 RTS (Request to Send)

In the 2816, this terminal is tied through at 2200 ohm resistors to the +12 volt s u p p l y. Both Pins 5 and 6 from the PC should be connected here.

TB7 Terminal 5 DSR (Data Set Ready)

Use of this terminal is optional. This terminal is used by the receiving equipment to tell the 2816 not to send data. When a ground or negative voltage is on this terminal, the 2816 will hold any data it has until this terminal is returned to +4 volts or greater. . If this terminal is not used, it should be jumpered to TB7, terminal 4 to insure that it will be held at a positive voltage. This terminal should be used with care. The 2816 will not send data if this terminal is not held high.
With a PC interface, this terminal should connect to Pin 20 of the PC. This is the DTR lead of the PC. The PC can place this lead low to make the 2816 hold data.

TB7 Terminal 6 DTR (Data Terminal Ready)

Use of this terminal is optional. When the 2816 has data to send, the voltage on

this terminal will be greater than 5 volts, signaling the receiving equipment that

the 2816 has data to send. After the data is sent and when there is no data to

send, the voltage will be less than -5 volts.

On a PC, this would connect to Pin 8. Pin 8 is the PC's CD (carrier detect) lead. The PC's program could monitor this lead to see when the 2816 has data to send.

9 PIN "D" CONNECTOR PINOUT (DB-9) AND
2816 TO PC INTERCONNECTION

Shown below is the pinout of the optional 9 pin "D" connector (DB-9) on the
back of the 2816. Also shown is how the 2816 would connect to a PC's pin
iffi
RS232 "D" connector (DB-25).

The 2816s 9 pin "D" connector (DB-9) is configured so that the pins will be

compatible with 9 pin RS232 "D" connectors on PCs. A DB-9 to DB-9 cable can

plug the 2816 into a PC. A gender change may be needed, but pin swapping is

not needed.
