The AVI-222 receiver utilizes the LADOT2070 “Loop Comm” protocol. Other protocols are available at customer request.
Channel Enable / Disable Switch: A front-panel switch is available to enable or disable the AVI detection. When the switch is in the DISABLE position, the channel will not recognize any of the coded signals. When the switch is in the ENABLE position, the channel operates in a normal manner.
Valid Indicator: Each channel has a front panel red LED that indicates the detection of an AVI code that has been programmed as “Valid.”
Fault Indicator: Each channel has a front panel red LED that indicates an open circuit loop condition.
Communication Port: The AVI-222 receiver has a front panel mounted DB-9 RS-232 connector that allows data to be communicated to and from external equipment. The AVI receiver status and all received AVI code values (either valid or invalid) are available through the communications interface. The AVI-222 receiver accepts commands to set individual codes as valid/invalid, clear all code validity to customer-specified default values, and reset AVI receiver channels.
Currently, the AVI-222 receiver utilizes the LADOT2070 “Loop Comm” protocol. Other protocols are available at customer request.
Receiver Address DIP Switches: A 4-position DIP switch located on the PC board is used to select one of sixteen possible address bit combinations for the AVI-222 receiver, resulting in a maximum 32 AVI receiver channels on a single serial communications link.
Solid State Outputs: Optically isolated 40 VDC maximum outputs.
Power: 12 to 30 VDC, 160 milliamps maximum.
