1747-KE Module Features
There are three communication ports on the front of the module.
They are:
• CONFIG - used to configure the module with an ASCII terminal.
This serial port accommodates RS-232/423, RS-422, and RS-485
communication interfaces. The CONFIG port is capable of
operating at 300, 600, 1200, 2400, 4800, 9600, and 19200 Kbps. It
is electrically isolated to 500V dc.
• DF1 - used to interface the module to a modem or other user
devices using DF1 protocol. This serial port accommodates
RS-232/423, RS-422, and RS-485 communication interfaces. The
DF1 port is capable of operating at 300, 600, 1200, 2400, 4800,
9600, and 19200 Kbps. It is electrically isolated to 500V dc.
• DH485 - used to interface the module with the DH-485 network.
This port is not isolated and cannot directly drive a multi-node
DH-485 network. You must use a 1747-AIC link coupler to
connect this port to a DH-485 network that includes multiple
SLC 500 processors.
The 1747-C11 or 1747-C13 cables can connect the interface module’s
DH-485 port to a 1747-AIC link coupler. The 1747-C13 cable can also
connect the module’s DH-485 port directly to a single SLC processor.
See page 4-11 for cable connections.
