User’s Manual of ICS-10x
4.4.7 Pair Connection – Remote mode
The parameter defines the maintenance status for listen for the pair connection. In effect, this converter will be acting as a TCP client. The screen in Figure 4-48 appears.
When the changed operation mode, the user should be changed the Serial Port Configuration.

•TCP Port Number
•Inactive Timeout
The TCP port that ICS-10X uses to listen to connections and that other device must use to contact ICS-10X. To avoid conflicts with well known TCP ports, the default is set to “1024”.
Use the parameter to set an inactive timeout. The unit drops the connection if there is no activity on the serial line before the set time expires. To disable the inactive timeout enter “0”.
Important!
While using Pair Connection mode for two RS-232 services distance extend, the DB9/RS-232 cables are very importance in this application. There are much kind of RS-232 cables, such as straight cable (standard) and Null-Modem cable. Please make sure the DB9/RS-232 cables match the below constriction:
Serial Device to ICS-10x/Remote (Slave) – Use the original RS-232 serial cable attached in the serial device package.
Host / Client to ICS-10x/Local (Master) – It has to use the Null-Modem cable!
Users can use the Null-Modem cable directly connect to the ICS-10x (Master), or use the Null-Modem DB9 connector, as the picture shows:
Once the Pair Connection mode of two ICS-10x be correctly configured but still fail link, check the RS-232 cables!
