Omni:Chron II
When connecting an Omni:Chron II using the SWIFT-485+, you will need a
cable with a DB9 female connector and the other end bare. The DB9
connector plugs into the R485 port at the OMC2, while the bare end of the
wire coming from DB9 pin #1 makes the positive connection to the
SWIFT-485+, and the bare end of the wire coming from DB9 pin #2 makes
the negative connection to the SWIFT-485+. Omni:Chron II’s can only
communicate at a rate of 9600 baud.
