Figure 10-8: CAN Link Connections for a Single Control Head Installation
An MRU and the control head have two CAN ports that enable supporting “daisy-chaining” multiple
control heads or other CAN devices. Figure 6-2 on page 31 shows the radio’s two CAN port connectors,
which are located near the center of the radio’s rear panel. Figure 10-2 (CH-100) on page 56 and Figure
10-5 (Ch-721) on page 58 show the two CAN port connectors on the control head’s rear panel.
CAN Cable CA-009562-nnn
(where nnn specifies cable length in feet)
NOTE #2: The XG-100M mobile radio may be located in the middle of the CAN link.
For a 2-head installation, two CAN cables would connect directly to the two CAN port
connectors on the rear of the radio, and each control head would require a CAN
terminator. When the radio is in the middle of the CAN link, no CAN terminator is
required at the radio. The radio can support up to six (6) control heads.

NOTE #1: CH-100 and CH-721 control heads cannot be
used together (i.e., mixed) within a radio installation.
NOTE #3: Right-Angle CAN Terminator MACDOS0010 also is available. This CAN
terminator can be used if the physical clearance at the back of the head is insufficient
for CAN Terminator CD-014027-001.
