Always Enabled Mode of Operation
This mode of operation is the simplest to understand. In this mode, the acceptor is always enabled. It will
accept all valid bills that are programmed to be accepted by the Configuration Card. Note: to enable this
mode on the acceptor, make sure the Configuration Card has been configured for "Always Enabled" mode.
The output of the bill acceptor is either the relay contacts (if a 120 VAC optional supply is used), or the Low
Level Non-Isolated Credit Line (see below for details).
Always Enabled Mode- Connections:
Power
120 VAC Model- Connect 120 VAC power to Pins 4 (Black wire) and 6 (White wire) on the 9-pin connector
(see Figure 1).
24VAC Model- Connect 24 VAC power to Pins 5 (Black wire) and 6 (White wire) on the 9-pin
connector
(see Figure 1).
