9.3.6 Control Head-to-Radio Ethernet Cable Connections
Figure 9-12 illustrates Ethernet cable connections for a single Control Head installation. Figure 9-13
illustrates this for a multi-head Control Head installation where, for example, one Control Head is located
at the main operator location and another is located near the rear of the vehicle.
To prevent damaging the radio, always connect power cables before connecting the
Ethernet cables.
If only removing the transceiver, always disconnect the Ethernet cable first and then the
power cable. When reinstalling the transceiver, always connect the power cable before
connecting the Ethernet cable.
Always connect or disconnect radio cables in the following sequence:
Connecting Cables:
1. Connect the DC power cable to each remote Control Head.
2. Connect the Ethernet cable to each remote Control Head.
3. Connect the DC power cable to the transceiver.
4. Connect the Ethernet cable to the transceiver.
Disconnecting Cables:
1. Disconnect the Ethernet cable from the transceiver.
2. Disconnect the DC power cable from the transceiver.

Figure 9-12: Ethernet Connection for a Single Control Head Installation
Follow this procedure for an installation which has only one Control Head. For a multi-control head
installation, refer to Figure 9-13 as necessary (up to five control heads can be daisy chained this way).
1. If the Ethernet cable was partially installed along with the red wire, as described in Section 9.2.2,
continue to install the Ethernet cable by routing it to the area near the rear of the Control Head.
