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-LNG module support RS-232, RS-422, and
RS-485 interfaces. Please look at 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.
