Installing The Communications Card

In The FX Series Digital Communications System

Understanding The Communications Card

The communications card provides serial data ports for interfacing such items as open architecture interface

applications, PC attendant positions, and the SMDA data printer.

NOTE: The serial data ports provided by the communications card are in addition to the two that are located on

the CPU board.

You can install communications cards at the front two positions on the auxiliary board.

With each communications card providing four serial data ports, and with the auxiliary board accepting two cards,

the system can have a total of 10 serial data ports. The system designates these ports as COM 3 through COM 10.

The maximum serial data transfer rate available through COM ports 3–10 is 19,200 baud.

Removing And Installing Circuit Boards in the Equipment Cabinet

CAUTION

Circuit boards for the FX Series system are susceptible to damage caused by electrostatic discharge, and

you must keep this fact in mind as you handle the circuit boards. Refer to the Comdial publication

IMI01-005, Handling Of Electrostatically Sensitive Components, for general information. Specific

handling precautions are also included in this installation instruction.

The FX Series system includes installed circuit boards when it arrives at your site. The system consists of two

parts—the computer portion and the telephony portion. (You will find the computer portion discussed in a

separate publication and not discussed here.) In the telephony portion of the FX Series system, the equipment

cabinet provides universal slots that will accept either line or station boards.

When removing or installing circuit boards in the FX Series cabinet, you must install a static discharge wrist strap

on your bare wrist, and adjust it for a snug fit. Be sure that the strap is touching bare skin and is not isolated by

clothing. Connect the wrist strap cord between the wrist strap and a AC or earth ground.

Unless a circuit board has a pre-charge port on its front panel, disconnect the AC power cord from the AC service

outlet and disconnect the cable between the cabinet and any external battery back-up assembly before you remove

or install the circuit board. However, if the board does include a pre-charge port, you can connect a standard

telephone handset cord between the pre-charge port on the circuit board and the pre-charge port on the power

supply assembly and remove or install the circuit board while the system is operating.

Whenever you remove a circuit board from the cabinet, immediately place the board in a static protection bag

while you still have your wrist strap in place and properly grounded.

Creating A Static Safe Work Area

When removing circuit boards from an installation location for servicing, always transport them to a static-safe

work area in static protection bags. If you do not already have a static-safe work area, you can create one by

arranging a work area as detailed in the illustration.

Installing The Communications Card

You can install up to two communications cards on the auxiliary board to attain a maximum of 8 serial data ports.

These eight ports plus the two serial data ports provided by the CPU board provides a system total of 10 serial

data ports.

1. Install your static discharge wrist strap on your bare wrist; adjust it for a snug fit. Be sure that the strap is

touching bare skin and is not isolated by clothing. Connect the wrist strap cord between the wrist strap and an

AC or earth ground

NOTE: With the common equipment in the installed position, the ground lug on the side of the cabinet is an

appropriate grounding point since it should have a heavy ground wire connected between it and a good

earth ground.

2. Disconnect the AC power cord from the AC outlet and disconnect the optional battery back-up assembly from

the cabinet power supplies.

3. Loosen the retaining hardware and remove the auxiliary board from the equipment cabinet, place it in a static

protection bag, and transport the board to the static-safe work area.

4. At the static safe work area, with your wrist strap in place, remove the host circuit boards and the

communications cards from their respective static protection bags.

5. Referring to the illustrations on the next page, orient the host circuit board and the communications card, and

attach them with the supplied hardware.

6. Place the auxiliary board

and its newly installed

communications card into a

static protection bag and

transport this assembly back

to the common equipment

cabinet.

7. With your static strap on

your wrist, remove the

board assembly from the

static protection bag and

install the board in its

designated board slot.

8. Make a final inspection to

ensure that the board

assembly is oriented

correctly and mated

properly.

9. Install and tighten the

supplied screws to secure

the circuit board assembly

to the board cage.

10. Plug the AC line cord into

the AC outlet, reconnect any

battery back up equipment

and switch on the power

supply.

Connecting Data Devices To The Communications Card

The interface connector between the external device and the communications card is a standard modular jack, and

each serial data communications port supports various baud rates, data bits, stop bits, parity, and flow control.

You can program these various options using database programming. Since the serial data ports are short-run, you

must keep the cabled distance between the data device and the data port to 50 feet or less when operating at data

speeds of 19,200 baud or to 500 feet or less when operating at data speeds of up to 9600 baud.

When preparing a data cable for connection to a data device, refer to the manufacturer’s manual for the equipment

being interfaced and make the following wiring connections:

•

Wire the common equipment RD (data from device to common equipment) connection to the device TD

(transmit data) connection.

•

Wire the common equipment TD (data to device from common equipment) connection to the device RD

(receive data) connection.

•

Wire the common equipment SG (signal ground) connection to the device SG (signal ground) connection.

•

If required for proper operation, wire the common equipment CTS (clear-to-send status from device to common

equipment) connection to the device RTS (request-to-send) connection.

NOTE: The common equipment requires a positive voltage, with respect to signal ground, in order to send data.

•

If the cable has spare wires, be sure to ground them so that they will not act as antennas and induce interference

into the system. Further, if there is a source of RF power nearby (such as a radio transmitter), use shielded cable

and ground the shield at both ends.

The default data format is shown in the following chart. Configure the data device that you connect to the

maintenance port to match the charted information.

Port Type Baud Rate Data Bit Stop Bit Parity Bit

COM 3–10 19, 200 8 1 0

CAUTION

As an added precaution against induced interference, route the data cable as far away from any

fluorescent lighting as you can reach, and make every effort to route the data cable perpendicular to all

other wiring.

NOTES:

1. Maximum distance between the serial data ports and the

external data equipment is based on the baud rate of the port.

The distance is limited to 50 feet when the port is operated at

19,200 baud and 500 feet when it is operated at speeds up to 9600 baud.

2. Some data devices require the CTS signal for proper operation.

Route CTS to the device as needed.
