Note the following:
V.10 (RS423). For balanced signals a
"0" = low voltage, is defined as terminal
A positive with respect to terminal B. For
unbalanced signals a "0" = low voltage, is
defined as terminal positive with respect
to GND. Cable length for Leased Line
Control should not exceed 20 m.
RS 366.
All balanced inputs and outputs
(A and B) use balanced line signals
according to V.11 (RS 422), while single
ended signals are in accordance with V.10
(RS423). The "0" = low voltage definitions
are the same as for V.10 above. Max
cable length, as for V.10 above.
