operate directly from external power any time that it is being supplied.
Otherwise, it functions on internal battery power.
The “Output Selection” switch determines the polarity of the leading
edge of the TTL compatible output signal. In the NON-INVERTING
position, the output signal on the BNC connector will be a negative going
5 to 0 Vdc pulse derived directly from the conditioned sensor output.
When the INVERTING position is switch selected, the BNC output
signal will be a positive going 0 to 5 Vdc, TTL compatible.

Recharging the Batteries
To recharge the SPSR-IM Interface Module batteries:
1. Connect the recharger/power supply or external power cable
to the “External DC” input connector.
2. Connect the recharger/power supply into a working ac outlet,
or the external power cable to a regulated power source of 5 to
12 Vdc.
3. Be sure the “Power” switch is in the OFF (CHARGE) position.
The red “CHARGE” LED will indicate that the batteries are
being charged. Allow up to 4 hours to fully charge.

Output: TTL compatible pulse, INVERTED or NON-INVERTED – switch
selectable. With an ROS (negative pulse) input, the output will be
a positive pulse when set to inverted or negative pulse when set to
non-inverted. Optionally, the output can be open collector (external
pull up is required).
