Appendix A: Microwave and Cellular ODU Confi gurations
Microwave ODU Wiring Harness
The minimum recommended AWG cables are 4-conductor 20 AWG or 2-conductor
16 AWG for new installations, although additional customer-specifi c cables may be
required for applications such as mast-lighting, off-air antennas, mast-cams, etc. In
addition, NewStream is backwards compatible with legacy CodeRunner CR2 and
MTX5000 van transmit Nycoil installations.
Selecting Function Cables
To select the cables for your wiring harness, select the functions that you require and
match the individual cables that are applicable to the particular requirements. These
cables should be included in the harness.
NewStream provides antenna polarity controls and serial control over the IF
interconnect cable plus feed power and polarity for the antenna connection to the ODU
or the IDU. For a new installation, the 8 pin connection on the ODU will be used. A
short jumper cable can be used for the antenna connection, therefore no cables need
to be specifi ed inside the Nycoil conduit for the antenna.
NewStream simplifi es the ODU cabling due to the higher voltage [48V] used to power
the ODU. The minimum recommended cables are:
• 4 conductor 20AWG Type N
• 2 conductor 16AWG Type N or
• Belden 8232 Triax cable
Cellular ODU Wiring Harness
The Cellular ODU uses a single coax type cable - RG59 or RG6 with TNC connectors.
Note that both 48 V DC power and data are passed over this coax cable.
