1.6 Connecting the Hardware
This section describes how to connect ATC-2000WF to serial devices for first time testing
purposes. We cover Wiring Requirements, Connecting the Power, Connecting to the
Network,
You should also pay attention to the following items:
Use separate paths to route wiring for power and devices. If power wiring and device wiring
paths must cross, make sure the wires are perpendicular at the intersection point.
Connecting the Power
Connect the 9-36 VDC power line with ATC-2000 power jack. When the power is
properly supplied, the .Link and DIS. LED will light in red and yellow color until the system
is ready, at which time the .Link. LED will be put out and DIS PWR LED still light.
