PMAC2A PC104 Hardware Reference Manual

When used as non-multiplexed I/O, jumpers E7 and E8 on the Acc-2P board select the I/O lines direction of the JTHW connector. This allows configuring this port as all inputs, all outputs or half inputs and half outputs. If E7 is removed or E8 is installed then the multiplexing feature if the JTHW port cannot be used.

Acc-1P or Acc-2P Handwheel Port (JHW / PD Port)

This port provides an extra encoder input or a set of pulse and direction outputs. Jumpers E3 and E4 on either the Acc-1P or Acc-2P boards select the function of this connector between encoder input or pulse and direction outputs. The handwheel encoder input can be linked to a servomotor for manual displacement or used by a motor as a secondary encoder for dual-feedback applications. There is no C index channel input on the handwheel encoder port. The pulse and direction outputs can be used, for example, to control an external laser device but not a stepper driver\motor, since this would require more than eight axes of motion control.

Optional Analog Inputs

The optional analog-to-digital converter inputs are ordered either through Option-12 on the baseboard or Option-2 on the axes expansion board. Each option provides two 12-bit analog inputs analog inputs with a ±10Vdc range.

Compare Equal Outputs

The compare-equals (EQU) outputs have a dedicated use of providing a signal edge when an encoder position reaches a pre-loaded value. This is very useful for scanning and measurement applications. Instructions for use of these outputs are covered in detail in the PMAC2 User Manual.
