Serial Cable Connection and Routing
The serial cable connects the mobile radio to the mobile computer located in the driver compartment.
To connect the serial cable, perform the following steps:
Step 1 Attach the 20-foot serial cable male connector (DB9M – see Figure 11)
to the mobile radio.
Step 2 Route the female connector (DB9F – see Figure 12) to the driver
compartment and connect to the serial port located on the rear of the
mobile computer.

Route the serial cable to minimize foot pressure and other potential stresses. Use split
loom tubing and nylon cable ties for cable protection.
If connecting a Voice Interface Unit, see page 28 for instructions.
Ethernet Setup
The user also has the option to connect the mobile radio and the mobile computer via Ethernet.
To connect the Ethernet crossover cable, perform the following steps:
Step 1 Attach the Ethernet crossover cable (minimum 20 feet) to the Ethernet port on the rear
of the mobile radio, as shown previously in Figure 2.
Step 2 Route the other end of the Ethernet crossover cable to the driver compartment and
connect to the Ethernet port located on the rear of the mobile computer.

Route the cable to minimize foot pressure and other potential stresses. Use split loom
tubing and nylon cable ties for cable protection.
Note that if installing a Voice Interface Unit (VIU), the Ethernet setup cannot be
used, as the VIU is a serial-only device.
Delay Timer Installation
To install the Delay Timer, perform the following steps:
Step 1 Secure Delay Timer to the trunk compartment of the vehicle inserting screws in the
appropriate locations using care not to puncture the vehicle’s gas tank.
Step 2 Route the black wire (#12 AWG) from ground connection on the Delay Timer to the
vehicle chassis (see Figure 13).
Step 3 Route and wire red wire (#8 AWG) from the positive (+) terminal connection on the
vehicle battery connection via the in-line fuse toward the battery connection on the
Delay Timer.
Connect the red wire (#8 AWG) to the two red wires (#12 AWG). Route and wire the
red (#12 AWG) wires to the two (2) battery connections on the Delay Timer.
