XL
A single external receiver may be deployed and connected to a pair of Mentor XL generators. This
simplifies the installation but will require a small amount of additional wiring adjacent to the Mentor
XL. Some data signals require termination and this should be configured using the appropriate setup
menus as shown in section 12.9.1. The table below shows wiring appropriate for a pair of Mentor XL.
A cable break out assembly is included with every smart antenna purchased from Trilogy. See below
for details.
The quantity of break-out cables required for particular applications is shown in the table below.
