Benefits:
• Independently manages up to 32 AISG devices with the use of a junction box(es)
• Controls actuators through the AISG protocol, where a digital address serves to identify and com-
municate with a specific actuator
• Six integrated smart bias tees with SMB connectors operate over internal modems to allow an AISG
signal to transmit to TMAs/top smart bias tees. Note that a dc 2.1 bias tee and SMB terminated
coaxial cable are also required
• 19” rack mountable (1RU)
• Controller interface opens through an Internet browser after connection has been set up
• Includes battery backup on internal clock
Since the ATC300-1000/2000 controller is hard-wired into the equipment cabin, a lightning protection
unit (ATLP200-001) and appropriate grounding are recommended. If the controller will be used in
an outdoor environment, it must be placed in a weatherproof enclosure. See Section 2 for mounting
instructions and safety precautions.
LED Features:
• Status LEDs located to the left of the Ethernet connection represent power and major alarms (Figure
1-2). The top green light indicates that the unit is powered. The bottom red status light indicates
that a major alarm has occurred which can be checked by looking at the alarm status.
• The AISG status LEDs are located next to the AISG port. When the left LED is illuminated green,
24 Vdc is available to the RS–485 bus (i.e., in the RET cable). When the right LED is illuminated
green, the RS–485 bus is powered with 24 Vdc and the controller is in the Wake mode. When the
right LED is red, there is a short. In this case, devices and cables must be checked.
