Port number
For Ethernet to RS-232 insertion, the insertion port number must be stated from a specific
UART start point. This number is entered as the Telnet port number when you establish
communication with the insertion port.
For the purposes of this discussion, consider the Ethernet insertion ports as serial (RS-232)
ports. The input insertion port number is the UART start point + 1. The output insertion port
number is the UART start point + 3. With the default UART start point of 2000, the input
and output insertion ports are:

Changing the starting point
By default the UART start point is 2000. You can change the starting port number by any of
the following methods:
Using the Product Configuration Software (see IN1804 Series PCS Help file)
•
• Using SIS commands (see the
RS-232 protocol
You also may need to set the RS-232 protocol of the addressed port to match the connected
device. You can do this using any of the following methods:
• Using the Product Configuration Software (see the IN1804 Series PCS Help file).
• Using SIS commands (see the
page 77).
