signal will be provided via a pair of dry contacts. The BDR provides the source voltage of
nominally +5 VDC and the return path to drive the signals. Refer to BDR Data 1 Port Cable
Pin-outs, for EIA-530 pin assignments. The diagnostic port (J4) is not connected during
normal operation. It is used for testing purposes. (Refer to paragraph 2.5.2.)
2.3 CABLE AND GROUND REQUIREMENTS
The following paragraphs contain the requirements for constructing the interconnect cabling
between the Andrew and vendor supplied equipment.
Construct the MDR power cables, using at least 16-gauge cable. Use the power cable to
ground the MDR.
Use RF coaxial cable to connect the antennas. The cabling must support potential bends in
the path from the mobile antennas to the radios. Loss through this cable must be less than 2
dB.
Construct data and computer signal cabling using 22 AWG shielded cabling. The BDR power
cable is a standard AC power cable using an IEC320 type plug.
All cables shall be shielded for EMI reduction.
