E SR-750-IM
 Connecting the OUT1/OUT2/OUT3 wires
• The OUT1 (OK) output is used as an output for successful reading and
verification of OK as a result of checking against the preset data.
• The OUT2 (NG/ERROR) output is used as an output for reading failure
and verification of NG reading as a result of checking against the
preset data.
• OUT3 (BUSY) is output any time the trigger input cannot be accepted.
For example, a busy signal will be output at initial start-up, during the
key operation, reading operation, etc.
The output form of each signal is photo MOS relay.
• Maximum rated load : 30 V DC (1 output: 50 mA or less, 3 Total
output 100 mA or less)
• Leakage current when OFF : 0.1 mA or less
• Residual voltage when ON : 1 V or less
 Wiring the RS-232C signal line
Connect to host devices (PC, PLC, etc.) as illustrated below:
z Connection to a PC
Connecting the Ethernet cable
Connect the Ethernet cable to the SR-750 Series in the following procedure.
1 Preparation of Ethernet cable
First, rotate the connector screw and align the protrusion position with the
positioning pin position in the connector.
2 Connect to the SR-750 main unit
Align the protrusion position of the connector screw with the white mark
position of the SR-750 Series Ethernet port. Then, insert straight to avoid
tilting the connector.
3 Tighten the connector
Rotate the connector screw in the arrow direction until it stops (approx.
180 degrees) and tighten it.
Installing the SR-750 Series
 Installation angle
The scanner of the SR-750 Series is tilted at a 15 degrees angle against
the code surface.
An optimal reading stability can be achieved when mounted as shown
below.

positioning pin
Rotate the connector screw so that
the protrusion and the positioning
pin come to the above position.
• When connecting the connector, insert it straight so it does not tilt.
Otherwise, the connector pin may be damaged.
• Tighten the connector screw correctly. If it is not tightened properly, the
connector may become loose due to vibration, etc. and connection failure
may occur.
• Do not repeatedly bend the root of the connector of Ethernet cable. Loose
connection may result.
• Do not mount the unit so its scanner face is nearly parallel to the code
surface.
The optimal calibration may not be achieved or the reading may become
unstable due to the light received from specular reflection.
• The distances or angles that can be used for reading may vary according
to the print quality and size of the code to be read or surrounding
environment. Use the test mode, etc. to confirm the most appropriate
mounting condition in the environment.

Reading distance
The angle of the SR-750 Series scanner is
15° with reference to the perpendicular
line from the back side of the main unit.
