Once the equipment is deployed, you can verify the signal strength by
entering into Command Mode and reading Register S123. This register
provides the average signal strength in dBm. The minimum strength for
communication is roughly -108dBm. For consistent reliable
communication, you should try to deploy the equipment such that signal
strength exceeds -95dBm.

Antennas and Cabling
This section describes the recommended procedure for installing cabling and
antennas for use with the pMXDDL2450 module.
3.2.1
Internal Cabling
The most common method for installing the module is to run a cable from the
module’s UFL connector to a reverse TNC bulkhead connector on the chassis
of the equipment as shown in Figure 3. This cable can be purchased from
Microhard Systems.
Figure 3 Suggested Internal Cabling
Cable losses are negligible for the short piece used within the chassis.
Additional losses up to 0.5 dB may be present in the MCX and Reverse TNC
connections.
