This null-modem crossover cable is easily made by combining
two “PC-Direct” adapter hoods with a mux-mux crossover cable
from DCB. This cable is used for configuration and is available
from your dealer. This is commonly called a "PC-to-PC null
modem cable".
Gateway to RTU
Since RTUs vary in pinout configuration, no standard cable
may be specified. Since the gateway pinout is similar to a PC
COM: port when configured in RS-232 mode, a PC-to-RTU cable
may be used that is the same cable that works between YOUR
PC and YOUR RTU.
Note that if the RTU has a pinout similar to a PC, then a cross-
over (null-modem) cable must be used.
