Connecting Terminals via RS-485 (Star Configuration)
A star network connects up to 31 terminals or sync time devices to the
computer. You can wire the terminals directly to the SWIFT-485+ or use J-
kits (junction boxes). Terminals can be located up to 4000 feet from the
computer
1. Run Category 3 (minimum) cable from the SWIFT-485+ to a terminal or
J-kit. If you connect directly to a terminal, use an RJ-45 or RJ-11
connector on the end that plugs into the terminal
2. Connect the AC power cord adapter to each terminal and plug the cord
into a wall outlet
3. Repeat these steps for each terminal in the network
