5.6 RS-232 Asynchronous Port
The RS232 port is used to connect to equipment such as PC/DVA system, and to PCs running remote fault
reporting software and the ASL Configuration Tool.
It is possible to define whether the RS232 port connection is direct or via a modem, and whether or not to
implement hardware flow control (i.e. suspend transmission when CTS is not asserted).
The default communications parameters are: 9600 bps, no parity, 8 data bits, 1 stop bit.
In order to configure the RS232 port proceed as follows.
1. Select Configuration System Misc Async-Port.
2. Move to, and toggle to the required CTS option in the left field:
[CTS disabled] Direct Connect
•
