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 intended for use on the LEN (Local Equipment Network) communications bus only. Do NOT connect the Navigator module to the CCN (Carrier Comfort Network®) connector, 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.

Manufacturer reserves the right to discontinue, or change at any time, specifications or designs without notice and without incurring obligations.
