RS-232 Asynchronous Port Module
RS-232 Asynchronous Port Module
The RS-232 Asynchronous port module provides 16 asynchronous RS-232 ports. Each
port has a data transfer rate of up to 115.2 Kbps. You can use RJ-45 connectors to
provide the port connections.
Figure 1-2
shows the panel of an RS-232 Asynchronous port module.
Asynchronous RS-232/20mA Current Loop Port Module
The Asynchronous RS-232/20mA Current Loop port module is a dual-mode port
module that provides 16 ports. Each port may be individually configured for RS-232 or
Current Loop. Each RS-232 port has a data-transfer rate of up to 115.2 Kbps. Each
Current Loop port has a data-transfer rate of up to 19.2 Kbps.
