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:
Channel 0
Serial Port-25-pin D-shell; supports standard EIA
RS-232C and RS-423; is RS-422A compatible
one stop-bit
BCC error check
no handshaking DF1 point-to-point
2400 bps
no parity
Keyswitch-selects processor mode
DH+ Programming Terminal Connection
to Channel 1A
8-pin mini-DIN, parallel with 3-pin connectors
of Channel 1A; use only when Channel 1A is
configured for DH+ communications
Channel 2
ControlNet Redundant Media Ports*
BNC; dedicated
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
