4.9 CONTROL UNIT / RF HEAD
INTERCONNECT
Figure 25 shows the interconnects between the
NewsCaster VT2 Control Unit and the mast
mounted RF Unit. To assist in preparing the
Control and Monitor cable, connector pin
assignments and recommended wire sizes are
provided. When Triax or Belden 1694 are
used, the only conductors required to pass
through the Nycoil for standard operation are
the coax (or Triax) cable (for power, data, and
70 MHz IF) and optional power conductors if
configured for Pan & Tilt. An auxiliary power
cable is required if using 75  RG-59 (or
optional 50  RG-58).
RF Head Connections
Perform the following:
• Connect the IF cable to the IF Interface
jack. (Refer to Figure 21, Detail 11.)
• Connect the antenna polarization cable.
(Refer to Figure 21, Detail 12.)
If the Pan/Tilt option is configured:
• Connect the Pan/Tilt Power cable to the
RF Head (7-pin). (Refer to Figure 21,
Detail 14.)
• Connect P1 (18 pin, male) of the Pan &
Tilt Power/Control cable to J1 “TO
PAN/TILT” on the RF Head. Connect P2
(17 pin, female) of the Pan & Tilt
Power/control cable to the Pan & Tilt
motor assembly. Refer to Table 11 and
Figure 18 for cable pin-outs. (Refer also
