Using Terminal and Switchpack Modes

Connect the 9-pin end of the terminal cable into a COM port on your PC. Plug the other end into the modular jack on the termination unit's front panel. If your PC requires a 25-pin connector to the COM port, see Appendix B, Cable Pin Assignments, for the correct cable pinouts.

Make sure the terminal parameters on your terminal or PC are set to:

￿9600 Kbps

￿8 bit character

￿No parity bit

￿1 stop bit

￿No flow control

Press Return at your terminal to activate the Main Menu. The system runs diagnostics and status checks as it comes up. After a few seconds, the Main Menu screen appears on your terminal. Menus are described in Chapters 4 and 5 for the DSX-1 and V.35 units, respectively.

Switching Between Terminal and Switchpack Modes

The following procedure is used to change the operating mode of the unit to either Terminal Mode (the default setting) or Switchpack Mode. Refer to Chapter 4 (for DSX-1-compatible units) or Chapter 5 (for V.35-compatible units) for information on changing configuration options using either of these modes.

"Procedure

Use electrostatic discharge protection when handling the circuit board. To change the mode:

1.Power down the unit and expose the circuit board by loosening the two screws on the back panel of the unit and sliding off the cover.

2.See Appendix C, Switchpacks and Jumpers, for jumper locations on your unit's board.

ÐUse jumper P11 for DSX-1-compatible units.

ÐUse jumper P8 for V.35-compatible units.

3.Place the jumper in the correct position for the desired mode.

ÐSwitchpack Mode is configured by placing the jumper on Pins 2 and 3.

ÐTerminal Mode is configured by placing the jumper on Pins 1 and 2.

4.If you are enabling Switchpack Mode: You must set the switchpacks and jumpers to your desired configuration. Refer to Appendix C, Switchpacks and Jumpers.
