ODU to the computer cannot exceed 100 meters.
• Fasteners: User must supply fasteners necessary to mount the ODU mounting bracket as well as the IDU at
their specific installation locations.
• Strap wire with electrical clips: To be used for grounding the ODU/IDU cable prior to installation. Prevents
static discharge that may have built up on the cable during installation process.

Understanding the Interface Between ODU and IDU
The IDU provides isolated 48 volts to operate the transceiver and digital base-band processor in the ODU. There
is an E1 interface that carries voice information from the IDU to the ODU. The E1 also provides communications
for housekeeping between the two devices, for SIM interfacing and "reset to factory defaults" commands. Lastly
there is an Ethernet connection thru the IDU connecting directly to the ODU base-band processor.
