Figure 4-5-7: Remote Pair Slave Mode Screenshot
The page includes the following fields:
Object Description
• TCP Keep-alive
Interval
TCP keep alive interval shows how many seconds the unit waits during an inactive
connection before checking its status. If the unit does not receive a response, it will drop
that connection. The default is 0 minute.
• Local TCP port
This parameter describes the TCP port that communicates with the connected device.
The setting slave and master destination IP parameters must use the same value to
achieve communication. The range of value is from 1 to 65535. The default is 5004 for
port 1, 5005 for port 2, 5006 for port 3 and 5007 for port 4
Using Remote Pair Connection mode for two RS-232 services for distance extension, the DB9/RS-
232 cables
are very important in this application. There are many different kinds of RS-232 cables, such as straight
cable (standard) and Null-Modem cable. Please make sure the DB9/RS-232 cables match the following:
 Serial Device to ICS-2X00/Remote (Slave) – Use the original RS-
232 serial cable attached in the
serial device package.
 Host / Client to ICS-2X00/Local (Master) – It has to use the Null-Modem cable!
Users can use the Null-Modem cable to directly connect to the ICS-2X00 (Master), or use the Null-
Modem
DB9 connector, as the picture shows:
Once the Pair Connection mode of the ICS-2X00 is correctly configured but the link is still not connected,
check the RS-232 cables!
