13.5 SIM Installation – ROV
The SIM can be installed on either the top-side or in the vehicle. There are advantages to both
methods which depend on the multiplexer capabilities. For SIM installation in the vehicle, the SIM
Controller board may be removed from the SIM or supplied as an additional item. The SIM
controller board uses a PC/104 size format but does not use the PC/104 bus.
