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
