INTERFACE: Serial ports - Asynchronous EIA-232
(CCITT V.24), -12v mark, +12v space. Full duplex
communication. Optional EIA-422 and current loop.
Parallel ports - Centronics protocol.
I/O MODULES: (Maximum 6 I/O modules per unit;
minimum 2 serial ports per unit.)
Four EIA-232 DTE ports (MOD 24-4C)
Four EIA-232 DCE ports (MOD 24-4CF)
Two EIA-232 DTE ports/two parallel ports (MOD 24-4E)
Four parallel ports (MOD 24-4A)
Four current loop ports (MOD 24-4L)
Four EIA-422 ports (MOD 24-4Y)
NOTE: Parallel communication is strictly unidirectional
(i.e., data flow may flow only from the parallel peripheral
device to the host device or from the host device to the
selected parallel peripheral device).
