2.0 DESCRIPTION

The Rockwell Modem (R96FT) is a purchased part from the Rockwell Corporation used in the GETC™ shelf. The

Rockwell Modem is used to transmit and receive 9600 bps serial data to and from four-wire dedicated unconditioned

telephone 1ines under control of the GETC shelf.

2.1 GETC SHELF

The GETC shelf (19D901868) is used to test the Rockwell Modem as part of the shelf assembly.

2.2 PHONE MODEM BOARD (ROCKWELL R96FT)

The Rockwell R96FT is a board level synchronous serial 9600 bit per second modem. The GETC logic

board contains phone 1ine interface circuits (T1, T2 etc.) that couple the phone modem to the phone line.

2.3 TEST SOFTWARE

The GETC shelf is used as a test fixture for the test of the Rockwell Modem.

The GETC exercises the testing of the Rockwell Modem via the built in test software known as SIMON on

the GETC.

5.1 PREPARATION FOR TEST

Refer to the GETC test specification for certain alignment procedures prior to testing of the Rockwell

Modem. Set up terminal with 19.2 KBaud rate, odd parity, full duplex, and all upper case letters. Connect

the terminal to the master communication link as follows:

SIGNAL GETC LOGIC TERMINAL

BOARD (D-TYPE CONNECTOR)

TXD J8-1 PIN 3

5.2 ROCKWELL MODEM TEST

The GETC shelf setup procedures to configure it as the test fixture for the Rockwell Modem follows. These

procedures need to be implemented only once on the specified GETC shelf to be used as the Rockwell

Modem test fixture.

1) Plug the Rockwell Modem into J3 on the GETC test fixture.

2) Install P11 between J11-1 and J11-2 on the GETC logic board.

3) Connect a jumper between J6-7 and J6-9 on the GETC.

4) Connect a jumper between J6-6 and J6-8 on the GETC.

5) Install a 680 ohm resistor (1/4 watt) between J6-8 and J6-9.

6) Adjust R1 to about half range on the GETC.

7) Adjust R2 to about half range on the GETC.

The procedures to test the Rockwell Modem follows:

l) Plug the Rockwell Modem into the test fixture.

2) Apply power (13.8 volts) to the GETC shelf and the SIMON welcome message is displayed on the

terminal. The GETC is DTP switch configured for SIMON operation prior to power up. See

19A701179 for dip switch set-up.

3) Type "TIM 19" on the terminal to set the time delay from RTS to beginning of data to 250

milliseconds.

4) Execute the SIMON command "MDS 1" to select the phone modem for subsequent BER

command.

5) Execute the SIMON command "BER DE-00=10". This command transmits data and

simultaneously checks to see that data is being received. The terminal should respond with the

following: Error Count = 0000 Receive Checksum = 00188123

If the terminal does not respond with the above data, the Rockwell Modem has failed the test and

needs to be returned to the vendor.

The test continually runs, outputting data to the terminal in 10 second intervals.

6) After four consecutive test periods (10 seconds per test period) with data outputted to the terminal,

the test can be terminated by pressing a CTRL Z or the ESC key on the terminal.

INTRODUCTION

The Rockwell R96FT is a synchronous serial 9600 bps

modem designed for multipoint and networking

applications. The R96FT allows full-duplex operation over

4-wire dedicated unconditioned lines. or half-duplex

operation over the general switched telephone network.

Proprietary fast train configurations provide training times

of 23 ms for V.29FT/9600/7200/4800, 22 ms for

V.27FT/4800. and 30 ms for V.27FT/2400. A 2400/4800

bps Gearshift configuration provides a training time of 10

ms. For applications requiring operation with international

standards, fallback configurations compatible with CCITT

recommendations V.29 and V.27 bis/ter are provided. A

300 bps FSK configuration, compatible with CCITT V.21

Channel 2, is also provided.

The small size and low power consumption of the R96FT

offer the user flexibility in formulating a 9600 bps modem

design customized for specific packaging and functional

requirements.

This data sheet corresponds to assembly number

TR96D400-061 and subsequent revisions.
