26 Reference Information
Pinouts
Check the calibration data sheet and pinout for your device.
See page 20 for additional important information about connecting your device to a computer for serial commands.
8-Pin Mini-DIN (Default)
Pin Function

Not Connected Optional: 4–20 mA primary output signal

Static 5.12 Vdc Optional: secondary analog output (4–20 mA, 0–5 Vdc, 1–5 Vdc, 0–10 Vdc) or basic alarm

Serial RS-232RX Input Signal Optional: RS-485 A

Analog Setpoint Input

Serial RS-232TX Output Signal Optional: RS-485 B

0–5 Vdc Analog Out Optional: 1–5 Vdc or 0–10 Vdc output signal

Power In

Ground (common for power, digital communications, analog signals, and alarms)
▲
Caution: Do not connect power to pins 1 through 6, as permanent damage can occur. It is common to mistake pin 2 (labeled
5.12 Vdc Output) as the standard 0–5 Vdc analog output signal. Pin 2 is normally a constant 5.12 Vdc.
