CONNECTIONS
The A1000 and A2000 have three connectors located on the rear panel,
two RS-485 connectors and one RS-232 connector. The RS-485
connectors are 4 position screw-terminal plugs labelled RS-485 IN and
RS-485 OUT. The RS-232 input connector is a female subminiature DB-9
connector labelled RS-232 IN. The functional description of each terminal
is labelled directly above the connector on the rear panel. The RS-485
descriptions are all preceded by letters which correspond to the color
coded wires used in standard telephone cable: (B) Black, (R) Red, (G)
Green and (Y) Yellow. All DGH hardware using RS-485 contains this color
coded nomenclature. Figures 1A & 1B show the rear panel connections
for the A1000 & A2000.
