Introduction
1.4.6. Connectors (J1 and J2)
There are two connectors on the MXH multiplier board; J1, which receives signals from a sinusoidal
encoder, and J2, that outputs the frequency-multiplied RS-422 pulses. The "multiplied" signals are then
taken to the controller through the breakout or interface boards. J1 is a 25-pin female "D" style connector. J2
is a 25-pin male "D" style connector. The pinouts for these connectors are listed in
The MXH box only uses the SIN, COS, and Marker signals. Hall effect, Limit, and the rest of the signals are
passed directly through the MXH box with minor or no modification. As with any high frequency signal
transfer over cables, strict guidelines for interconnecting cables should be followed for noise-less, properly
phased signal delivery.
