8-pin mini-DIN cables (DC series)

Wire colors for 8-pin mini-DIN cables are labeled according to our standard 8-pin mini-DIN pinout:

Black – primary 4-20 mA current analog output
Brown – secondary analog output (if used, DC only)
Red – digital serial input (RS-232Rx or RS-485 A)
Orange – setpoint input or remote tare (via grounding)
Yellow – digital serial output (RS-232Tx or RS-485 B)
Green – primary 0-5, 1-5 or 0-10 volt DC analog output
Blue – DC power input
Purple/White – ground

Double-ended 8-pin RS cables for BB3 and BB9

Double-ended 8-pin mini-DIN RS cables are perfect for connecting your instruments to a BB3 or BB9 multi-drop breakout box. RS cables have male 8-pin connectors on both ends and carry only power and digital (RX/TX) signals.

3 ft/0.9 m (DC-32RS)
6 ft/1.8 m (DC-62RS)

6-pin locking industrial cables (IC series)

Wire colors for 6-pin locking industrial cables are labeled according to our standard 6-pin industrial pinout:

Black – ground
Brown – primary DC voltage or 4-20 mA current analog output
Red – DC power input
Green – setpoint input or remote tare (via grounding)
Blue – digital serial output (RS-232Tx or RS-485 B)
White – digital serial input (RS-232Rx or RS-485 A)

9-pin and 15-pin D-sub cables (DB series)

Double-ended D-sub cables

Double-ended (female-female) D-sub cables can be used to connect Alicat instruments with male D-sub connectors to programmable logic controllers (PLC’s) and other devices with the same connector.

9-pin: 10 ft/3.0 m (Part 510199)
15-pin: 15 ft/4.6 m (Part 510368)

*Note: Alicat instruments equipped with 9-pin D-sub connectors do not have the same pinouts as common serial cables. Proper connection to computer serial ports is accomplished via our MD8DB9 8-pin mini-DIN to serial adapter cable.

Conversion Cables

8-pin mini-DIN to 9-pin serial (D-sub)

The best way to connect a single Alicat device to a serial port on a computer is by using our MD8DB9 8-pin mini-DIN to 9-pin serial adapter cable (6 ft/1.8m length). This cable directly converts the ground, transmit and receive signals from the 8-pin mini-DIN that is standard on most Alicat instruments to the corresponding pins on a computer’s 9-pin D-sub serial port.

To connect multiple Alicat devices to a computer with a single serial port, please see our multi-drop breakout boxes.

8-pin mini-DIN to USB 2.0

Alicat instruments may be connected to computers USB ports by using our 8-pin to USB conversion cables.These cables transmit serial communications (RS-232 or RS-485) but will not power your Alicat instrument from a computer’s USB port. Your computer may require the installation of a USB device driver.

RS-232: 6 ft/1.8 m (USB-MD8-232)
RS-485: 6 ft/1.8 m (USB-MD8-485)

Other connectors are possible on this custom USB conversion cable:

6-pin (male) to USB for RS-232: 6 ft/1.8 m (USB-IC-232)
6-pin (male) to USB for RS-485: 6 ft/1.8 m (USB-IC-485)
9-pin (female) D-sub to USB for RS-232: 6 ft/1.8 m (USB-DB9-232)
9-pin (female) D-sub to USB for RS-485: 6 ft/1.8 m (USB-DB9-485)
15-pin (male) D-sub to USB for RS-232: 6 ft/1.8 m (USB-DB15-232)
15-pin (male) D-sub to USB for RS-485: 6 ft/1.8 m (USB-DB15-485)

To connect multiple devices to a computer using a single USB port, please see our multi-drop breakout boxes.
