1747-DPS2 Port Splitter
1747-DPS1 and 1747-DPS2 Controller Port
The controller port configuration turns on at DF1 full-duplex, 8 bits, no parity, 1
stop bit, but it autobauds between 19.2 and 38.4 Kbps as well as auto-checksums to
either CRC or BCC. This lets you use the controller’s maximum baud rate and to
match the controller’s checksum configuration.
1747-DPS1 and 1747-DPS2 Prog/HMI Port
The Prog/HMI port is respond only. This DF1 port, intended for use with a
programming station or HMI, has a 9-pin male D-shell connector. The port
configuration is fixed at DF1 full-duplex, 19.2 Kbps, 8 bits, no parity, 1 stop bit, and
CRC checksum.
IMPORTANT
Do not attempt to initiate any message instructions from the controller
connected to the Controller port until the port splitter has completed its
autobaud and auto-checksum detection, as indicated by the solid OK status
indicator.
IMPORTANT
When configuring the RSLinx Classic DF1 driver, set the device to match what
is connected to the controller port. Set the baud rate to 19.2 Kbps, parity to
none, stop bits to 1, error checking to CRC, and protocol to full-duplex. Do not
attempt to click Auto-configure.
