3 Push the module into place until it seats firmly in the backplane.
CaUTION: The PTQ module is hot-swappable, meaning that you can install and remove it while
the rack is powered up. You should not assume that this is the case for all types of modules unless
the user manual for the product explicitly states that the module is hot-swappable. Failure to
observe this precaution could result in damage to the module and any equipment connected to it.
5.1.4 Cable Connections
The application ports on the PTQ-MCM module support RS-232, RS-422, and
RS-485 interfaces. Please inspect the module to ensure that the jumpers are set
correctly to correspond with the type of interface you are using.
Note: When using RS-232 with radio modem applications, some radios or modems require
hardware handshaking (control and monitoring of modem signal lines). Enable this in the
configuration of the module by setting the UseCTS parameter to 1.
RS-232 Configuration/Debug Port
This port is physically a DB-9 connection. This port permits a PC based terminal
emulation program to view configuration and status data in the module and to
control the module. The cable for communications on this port is shown in the
following diagram:
The Ethernet port on this module (if present) is inactive.
