Voltage levels:
T, PT = -26.3 ~ 27.8 VDC
R, PR = 0.0 VDC (GND)
(Reference to SG ground)
T/R wires are always required; PT/PR are additional power wires required only for long station runs or when operating on
reserve power per Table 8-D. PT/PR may be used with normal station runs also.
RS-232 cable length is max 50 ft with 24 AWG wire.
DIUs can be connected to circuits 1 ~ 7 with PDKU1; all Base Unit, KCDU, and PDKU2 digital circuits support DIUs.
Expansion Unit slots 04 and 05 only can support DIU.
KCDU provides circuits 1 ~ 4 only.
