Chapter 5. Appendix A Connector pinouts

5.1 Appendix A.1 Output port and breakout box RECORDER connector

Models with a 26-pin mil-spec plug (02E-16-26P) have the following pin assignments.

Pin

Function

A

Velocity +ve, vertical channel

B

Velocity –ve, vertical channel

C

Velocity +ve, N/S channel

D

Velocity –ve, N/S channel

E

Velocity +ve, E/W channel

F

Velocity –ve, E/W channel

G

Mass position, vertical channel

J

Mass position, N/S channel

L

Mass position, E/W channel

M

– 12 V DC supply (3-way power option)

N

Signal ground

P

Calibration signal (all channels)

R

Calibration enable (all channels)

V

N/S centring motor (remote centring option)

W

E/W centring motor (remote centring option)

X

Vertical centring motor (remote centring option)

Y

Motor return (remote centring option)

b

Power ground

c

+ 12 V DC supply

These outputs are compatible with the CMG-3ESP, so you can use CMG-3ESP handheld control units and breakout boxes to monitor the low-gain velocity outputs and calibrate. Note: 40T-1 units with the optional additional high-gain outputs cannot be used with a CMG-3ESP breakout box. The pinouts for these sensors are given in the next section.

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