INSTALLATION
1. The Navigator display module is intended to be a mobile
device, so there are no holes in the device for permanent
mounting. The module has a magnetic mount that is
strong enough to hold the device in place on any clean,
dry metal surface.
2. The Navigator module is powered through the
ComfortLink Main Base Board (MBB). The Navigator
module has a modular telephone style (RJ14) connector
and should be connected to a specific terminal block in
the control box as found in Table 1. This device is intend-
ed for use on the LEN (Local Equipment Network) com-
munications bus only. Do NOT connect the Navigator
module to the CCN (Carrier Comfort Network®) con-
nector, as it may damage the device.
3. See Fig. 2-8 for Navigator LEN connection locations in
the units.
4. See Fig. 9 for Communication board details.
