This section contains interconnect drawings for installing a GTR 20 unit(s) into a G3X system. GTR 200
units may also be installed into a G3X system, but may use different connections than the GTR 20. Use the
interconnect drawings in the GTR 200 Installation Manual (190-01553-00) for installing a GTR 200 into a
G3X system. Table 25-1 lists the interface methods that can/cannot be used for GTR 20/200 to G3X
systems.
NOTE
The GTR 20 wiring diagrams in this section use only CAN connections, the GTR 200
Installation Manual shows both CAN and RS232 connections.
