Switch S1-3:Tx Clock Invert

Switch S1-3 allows the user to invert the transmit clock originating in the 2720. When S1-2 is set for transmit clock, it may be necessary to invert the transmit clock to allow for delays due to long cables.

Switches S1-4 and S1-5: Line Build Out

Use Switches S1-4 and S1-5 to set the Line Build Out (LBO). The Line Build Out varies the pulse shape and attenuation of the signal sent to the network. The amount of Line Build Out depends on NetLink™ T1’s distance to the last repeater. The telephone company providing the service will advise on the amount of LBO necessary. In most cases the default setting will suffice.

3.2 SOFTWARE CONFIGURATION

The Model 2720 features a menu-driven command system that allows you to monitor/configure its operating parameters. Follow the instructions below to configure the Model 2720 using the software selections:

1)Plug the 9-pin male end of the cable to your terminal or com- puter’s DB-9 serial port and start up the terminal emulator software if necessary. Plug the miniature stereo plug into the rear of the unit. The small recessed jack on the left side of the unit is the control port jack.

NOTE: If your terminal uses a DB-25 connector, please use a DB-9 to DB-25 Adapter to connect to the cable.

2)Power up the terminal and set its RS-232 port as follows:

9600 Baud

8 data bits, 1 stop bit, no parity Local echo off

ANSI or VT-100 emulation

3)Here is an example of a terminal emulator setup session. In normal font are the various parameter types. In bold type are the values that should be used for best results. Your terminal program’s setup screen may differ from this one:

Baud rate: 9600

Parity: None

Data Length: 8

Stop Bits: 1

Default terminal type:

VT100

 

Local Echo:
