Mount the core processor

Use this section only if you are installing a remote transmitter using a remote core
processor or a remote enhanced core processor. See

Figure 1-6

. If you have a 4-wire remote

installation, go to

Section 3.1

.

Figure 2-3

shows both types of core processors and mounting bracket. Using the mounting

bracket, mount the core processor in a location compatible with the cable length
requirements discussed in

Section 1.2
