Use this port with ASCII or DF1 full-duplex,
half-duplex master, and half-duplex slave
protocols. The port's default configuration supports
processor programming:
Keyswitch-selects processor mode
Channel 0
Serial Port-25-pin D-shell; supports standard EIA
RS-232C and RS-423; is RS-422A compatible
DH+ Programming Terminal Connection
to Channel 1A
8-pin mini-DIN, parallel with 3-pin
connectors of Channel 1A
one stop-bit

Channel 0 is optically coupled (provides high electrical
noise immunity) and can be used with most RS-422A
equipment as long as:
termination resistors are not used
the distance and transmission rate are reduced to
comply with RS-423 requirements
