RS232 Adapter

Connect one end of a null modem cable to the console port on the CyberSWITCH, and the other end to the communication port on the PC. On the PC you must then execute a communication package to emulate a terminal (VT100). Your communication package should support file transfer (Xmodem and ASCII) for software upgrades and installations.

Use the following default values for your communication package:

Baud rate	9600
Parity	None
Data bits	8
Stop bits	1
Duplex	Full

CHANGING THE BAUD RATE

The baud rate is changeable. The default rate performs well for configuration changes. A faster rate is useful, however, to download new software upgrades to your system.

To change the baud rate through CFGEDIT:

1.Select Physical Resources from the main menu.

2.Select Data Line from the physical resources menu.

3.Follow the instructions to make changes to the ASYNCMDM.

4.When asked, enter the baud rate you want to use.

5.Step through the remaining parameters. The last entry will ask you if you would like to save your changes. Answer yes.

6.To make the new baud rate effective, restart the system (with the restart command).

7.Change the communications package you are using to the same baud rate.
