The pulse signal on the connector marked “Output” provides a sharp
leading edge for reliable and repeatable triggering of the connected
device. This output is capable of driving a hundred feet of coax cable.
Be sure to select the direction (0 to 5 Vdc or 5 to 0 Vdc) of this signal
to provide the required polarity of the leading edge to properly trigger
the connected equipment.
BATTERY DISPOSAL
Prior to disposing of the SPSR-IM, the user must remove the Nickel Metal
Hydride batteries. To do this, remove the four (4) rubber feet on the bottom of
the unit. This will expose four (4) screws that must be removed to dismantle
the bottom case piece, exposing the batteries. Remove the batteries and place
tape over the battery terminals to prevent them from shorting. The batteries
should be sent to a recycling center or returned to the factory. The rest of
the parts may now be disposed of.
NOTE: This product contains Nickel Metal Hydride (NiMH) batteries.
Replace only with the same type of battery – Rechargeable NiMH.

INTRODUCTION
The SPSR-IM Self Powered Sensor Interface Module is a self-contained,
rechargeable battery powered device for developing a TTL compatible one
pulse per revolution output for triggering external equipment such as vibration
analyzers, spectrum analyzers, stroboscopes, data acquisition equipment,
tachometers, balancers, waveform analyzers and magnetic tape recorders.
The S P SR- 115/2 3 0 is
comprised of the SPSR-IM
Interface Module, which
provides power to a sensor
and couples the sensor to
a BNC output; an input
sensor with a visible red
LED light source (ROS-P);
and a battery recharger.
Optional sensors such as an optical
laser sensor (ROLS-P-not shown),
in f r a red se nsor (IRS-P) , or an
amplif ied magnetic sensor (MT-
190P) may also be combined with the
SPSR-IM Interface Module when
appropriate. (See separate instructions for these confi gurations.)

SPSR-115/230 Series - SPSR-IM with ROS-P
The SPSR-115/230 consists of the SPSR-IM Interface Module described
above, an ROS-P Remote Optical Sensor with eight foot cable and mounting
bracket, and a PSC-2U (115/230 Vac) external power connection. One foot
of T-5 Refl ective Tape is also supplied.
ROS-P
When connected to the SPSR-IM as described above, the ROS-P
illuminates the target with a visible red light from a high intensity LED
and detects the refl ected pulses from the rotating refl ective tape target
with an internal photo-detector. The ROS-P Remote Optical Sensor is
capable of detecting a refl ected pulse from T-5 Refl ective Tape targets
at distances of up to 3 feet and angles up to 45 degrees from the target.
The sensor is supplied with a set of two M16 jam nuts and a 90° angle
slotted aluminum mounting bracket.
For most applications, a 1/2” square piece of T-5 Refl ective Tape should
be applied to a clean area on the rotating object. The sensor should be
mounted and optically aligned to illuminate the refl ective target once per
revolution. It is recommended that the optical sensor be placed at a
slight angle (approximately 10-15 degrees) from perpendicular, so
that the sensor will detect only the refl ected pulses from the target.
The sensor should be at least 2 inches and no more than 3 feet from the
target. The green LED On-Target Indicator on the ROS-P will blink at
the input frequency or be continuously illuminated when properly aimed.
Operating the SPSR as a triggering source
Once the ROS-P input sensor is properly mounted and aligned, further
connections and operation should proceed in accordance with the
functions and descriptions under the SPSR Interface Module sections
entitled ‘Connections’ and ‘Controls’.

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.

Unit operational = solid green
Unit charging = blinking red
Charging done = solid red
NOTE: Short red blinks followed by long blink = Charge error,

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).

FUNCTIONS AND OPERATION
SPSR Interface Module
The SPSR Interface Module (SPSR-IM) provides power to the input
sensor, receives and optionally inverts the return pulse signal, and provides
a switch selectable positive going 0 to 5 Vdc or negative going 5 to 0 Vdc
pulse train trigger output on a BNC connector. Connections and operation
are common to all SPSR models. Fully charged internal NiMH batteries will
typically provide greater than 40 hours of continuous operation. In addition,
the SPSR system can be operated continuously on external power by use of
the recharger/power supply or cable provided.
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.
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. When using the CA-
DCSPSR cable, connect the cable to the connector marked “External
DC” on the SPSR-IM and connect the cigarette lighter connector to
the appropriate power source.
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
