KEYENCE SR-700 Series - Manual (Page 3)

3 E SR-700-IM
Connection and Wiring Method
 Connection to the communication unit
Connect the connector to the communication
unit (N-R2/UB/R4/L1).
Refer to the communication unit instruction
manual for more details.
 Connector pin alignment
* The shielded wire is connected to a signal ground.
It is possible to change the functions of the input terminals and output
terminals. Refer to the user's manual for making these changes.
 Connecting the power
 Input terminal 1 and Input terminal 2 wiring
These are non-voltage inputs. Connect relay contacts or NPN open collector
outputs.
• The TIMING and PRESET inputs are non-voltage inputs.
• TIMING (Input terminal 1) is input to initiate the 2D code and barcode
reading.
• PRESET (Input terminal 2) is input to preset (register) the 2D code and
barcode data on the SR-700 Series.
 Output terminal 1, Output terminal 2, Output terminal 3
and Output terminal 4 wiring
These are NPN open collector outputs.
• OK (Output terminal 1) is output for a successful reading when a check
against preset data is successful.
• NG/ERROR output (Output terminal 2) is output for an unsuccessful
reading when a check against preset data fails.
• ERROR (Output terminal 3) is output for an unsuccessful reading.
• BUSY (Output terminal 4) is output when preset data registration has been
completed and internal processing is taking place.
When BUSY is output, TIMING (Input terminal 1) cannot be input.
 RS-232C wiring
Use the following wiring when connecting to a PC or a PLC.

• Do not use a reverse connection for the power supply. Doing so may
damage the unit.
• Use a stable power supply that is 5 VDC +5%, -10%.
Using a power supply that exceeds this range may damage the unit.
