Notes:
- If the sense lines are not used, SENSE – HIGH must be tied to EXCITATION – HIGH and SENSE – LOW must be tied to EXCITATION – LOW.
- Incorrect wiring of these ports can cause damage to the internal circuitry of the unit. Please contact Interface if you have questions or need assistance with these configurations.

Notes:
- Pins 1 through 4 are used for RS232 ASCII command set communications. Use 8 data bits, no parity, 1 stop, and set the baud rate using the Com baud rate entry on the System Options menu.
- The printer uses RS422 differential signaling on pins 5, 6 and 10. Baud rate for the printer is selectable using the Printer Baud entry on the System Options menu.
- Pins 7, 8, 14 and 15 are used for RS485 ASCII command set communications. Use 8 data bits, no parity, 1 stop, and set the baud rate using the Com baud rate entry on the System Options menu.

Notes:
- Limits are optically isolated solid state switches that can control AC or DC voltage. Peak blocking voltage is 350V, maximum continuous current is 120 mA.
- Digital inputs are opto-isolated with internal current limiting resistors. Voltage range is +4 to +22 VDC on the “HI” input with respect to the “LO” input. Other voltage ranges are possible with added external resistors, contact Interface for details. If isolation is not required these inputs may be operated using the +12 VDC supplied on pin 26 and the GND on pin 24.
Digital I/O Connector
- The source and scaling of ANALOG – OUT is selected through the menus.
- The HIGH BANDWIDTH – OUT is a buffered analog output permanently connected to the load cell channel.
- If the 4-20 mA Option is purchased.
