Communication
For RS-232 communication use the terminal block for power and the DB-9 connector for communications. Provide 8-
36 VDC power (20 mA minimum) by connecting to the +supply to the PWR+ terminal. Connect the –supply to the
PWR- terminal adjacent to PWR+. For communications connect the receiving device to the M1500’s DB-9 (female)
serial port (see DB-9 Pin Out Table above) or to the M1500’s RX and TX terminals. Terminal labels follow RS-232
standard TIA/EIA-232.The digital interface draws 20 mA of current or less.

For RS-485 communication use the terminal block for power and communication. Provide 8-36 VDC power (20 mA
minimum) by connecting to the +supply to the PWR+ terminal. Connect the –supply to the PWR- terminal adjacent to
PWR+. For communications connect the receiving device to the M1500’s A and B terminals. The digital interface
draws 20 mA of current or less.
