Chapter 6. Connector pin-outs

6.1 Output port and breakout box RECORDER connector

This is a standard 26-pin military specification bayonet plug, conforming to MIL-DTL-26482 (formerly MIL-C-26482). A typical part-number is 02E-16-26P although the initial “02E” varies with manufacturer.

Suitable mating connectors have part-numbers like ***-16-26S and are available from Amphenol, ITT Cannon and other manufacturers.

Pin assignments used when the High Gain option is not fitted:

Wiring details for the compatible socket, ***-16-26S, as seen from the cable end.

Note: Pins V, W, X and Y are only used when the remote centring option is fitted.

These connectors are plug-compatible with the Güralp 3ESP, so you can use Güralp 3ESP hand-held control units and breakout boxes to monitor the low-gain velocity outputs and run calibrations. Pressing ENABLE and CENTRE on a Güralp 3ESP hand-held control unit activates pin U and switches the 40T into 1 second mode for as long as the buttons are held down. You must do this before you can monitor mass position outputs, e.g. for offset zeroing.

Note: 40T units with the optional additional high-gain outputs cannot be used with a Güralp 3ESP breakout box. The pin-outs for these sensors are given in the next section.

Pin R, Calibration enable, is equivalent to the vertical calibration enable line on a Güralp 3ESP, so you can calibrate all channels by setting up Scream! or a hand-held control unit to calibrate the vertical channel.

6.2 Output port and breakout box RECORDER connector (high-gain option)

These units use the same plug with the following pin assignments. High gain velocity outputs are denoted HGV.

This is a standard 26-pin military specification bayonet plug, conforming to MIL-DTL-26482 (formerly MIL-C-26482). A typical part-number is 02E-16-26P although the initial “02E” varies with manufacturer.

Suitable mating connectors have part-numbers like ***-16-26S and are available from Amphenol, ITT Cannon and other manufacturers.

6.3 Breakout box power connector

This is a standard 10-pin “mil-spec” plug, conforming to MIL-DTL-26482 (formerly MIL-C-26482). A typical part-number is 02E-12-10P although the initial “02E” varies with manufacturer.

Suitable mating connectors have part-numbers like ***-12-10S and are available from Amphenol, ITT Cannon and other manufacturers.
