The 1738-232ASCM12 and -485ASCM12 serial-interface modules offer a serial-link
communication interface solution for peripheral products with:
y RS-232 ports
use the 1738-232ASCM12
y RS-485 and RS-422 ports
use the 1738-485ASCM12
These modules allow a device with serial-interface output, i.e., bar code readers, to
communicate up to 128 bytes of ASCII data onto any network supported by ArmorPoint
I/O. Each module is a single-channel, full-duplex interface and is rated for up to 38.4
kbaud. LED indicators on the modules offer diagnostics for the module, ArmorPointBus
backplane, and transmit/receive status indication.
11773388--SSSSIIMM2233
The 1738-SSIM23 module collects serial data from industrial absolute-position encoding
sensors that use standard SSI protocol. The SSI module is inserted into an ArmorPoint I/O
terminal base that provides common power, communications, and wiring connections for
the SSI sensors.
