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.
