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 – RS-232 digital serial input
  • Orange – setpoint input or remote tare (via grounding)
  • Yellow – RS-232 digital serial output
  • Green – primary 0-5, 1-5 or 0-10 volt DC analog output
  • Blue – DC power input
  • Purple/White – ground

Single-ended 8-pin cables

Single-ended 8-pin mini-DIN cables transmit power, analog and digital signals. They have a male 8-pin connector on one end and are blunt cut on the other end, for custom wiring of your Alicat instrument to your system. Single-ended 8-pin cables come in the following lengths. (Custom lengths are available.)

  • 6 ft/1.8 m (DC-61)
  • 6 ft/1.8 m with right angle connector (DC-6RT)*
  • 25 ft/7.6 m (DC-251)
  • 50 ft/15.2 m (DC-501)
  • 75 ft/22.9 m (DC-751)
  • 100 ft/30.5 m (DC-1001)

*The DC-6RT has a right-angle connector for use in tight spaces. This cable is only available in the 6-foot length (1.8m).

Double-ended 8-pin cables

Double-ended DC Series cables have male 8-pin connectors on both ends and carry power, analog and digital signals. They are available in the following lengths:

  • 6 ft/1.8 m (DC-62)
  • 25 ft/7.6 m (DC-252)
  • 50 ft/15.2 m (DC-502)
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 – RS-232 digital serial output
  • White – RS-232 digital serial input

Single-ended 6-pin cables

Single-ended 6-pin locking industrial cables transmit power, analog and digital signals. They have a male 6-pin connector on one end and are blunt cut on the other end, for custom wiring of your Alicat instrument to your system. Single-ended 6-pin cables come in the following lengths. (Custom lengths are available.)

  • 10 ft/3.0 m (IC10)
  • 20 ft/6.1 m (IC20)
  • 50 ft/15.2 m (IC50)
Double-ended 6-pin cables

Double-ended IC Series cables have male 6-pin connectors on both ends and carry power, analog and digital signals. They are perfect for connecting your meters and controllers to a BB3 or BB9 multi-drop breakout box. They are available in the following lengths:

  • 10 ft/3.0 m (IC102)

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.
