EXAMPLE RS-422 CONNECTION FROM PC TO GC
This section demonstrates an example RS-422 connection from a PC to GC that is accomplished
through use of an asynchronous line driver / interface device. The line driver device serves as an
interface between the RS-232 output of the PC and the RS-422 protocol needed for long distance
serial input to the GC. Specifics of the line driver are as follows:
-
"Black Box" brand,
-
Model LD485A-MP "RS-232/RS-485 Multipoint Line Driver",
-
RS-232 input (to connect to the PC), and
-
RS-422 or RS-485 output (to connect to the GC).
RS-422 line terminations are illustrated in Figure A-9, below, and jumper and switch settings to
configure the line driver device are listed in Table A-2, next page. (NOTE: For this example, a
straight-through RS-232 serial cable is used to connect between the PC and the line driver.)
