2.1.1 Connections
Connect the input sensor via the 1/8” [3.5 mm] phone plug to the
mating connector on the SPSR-IM. This sensor may remain connected
even when recharging the internal batteries of the SPSR-IM.
NOTE:
Do not plug an input sensor into the SPSR with the Power
switch in the ON position. Before plugging the sensor in,
switch the power to OFF and unplug any external power
supply.
Connect the output signal cable to the BNC connector on the
opposite end of the SPSR-IM and to the external equipment to be
triggered.
If operating from the recharger/power supply, connect the recharger
to the connector marked
EXTERNAL DC
on the SPSR-IM
and connect
the wall unit to the appropriate power source.
2.1.2 Controls
The
POWER
switch on the SPSR-IM controls both the operation and
the charging of the system. The unit will only charge from external
power in the power OFF position. In the power ON position, the unit
will 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 V dc 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 V dc, TTL compatible.
