Npaq® Hardware Manual
2.8.1. High-Speed Differential Outputs (J8)
The High-Speed Outputs can be used for general purpose user I/O or as special firmware features (Encoder
Echo and Clock and Direction).
Encoder Echo
The High-Speed Outputs can be used to echo up to three channels of encoder quadrature signals (see
). For more information on echoing encoder signals out of the Npaq, see the ENCODER OUT command
in the A3200 Help file.
Clock and Direction
High-Speed Outputs 11 and 12 (pins 7 through 10) can be used as clock and direction outputs for driving an
external device. For more information on using clock and direction outputs with the Npaq, see the
PULSE command in the A3200 Help file.
