Option 6 - Quad 3-channel encoder isolate board with 4

40-cm (16 inch) cables to ACC-8D,8E,8F

Acc-8D Option 6 is a separate board designed to sit alongside the main Acc-8D board. Acc-8D Option 6 provides the capability to optically isolate four incremental encoders from PMAC’s digital circuitry. This can be important for signal integrity in noisy environments. (Usually, differential signals and cable shielding are tried first.) Because the encoders are isolated from PMAC, a separate 5V power supply is required for the encoders.

The encoder signals and the power (5V and GND) for the encoder side of the board are brought in through Terminal Block 1. The encoder signals are passed on to PMAC either through (provided) 10-line flat cables that connect JENC1 through JENC4 on Option 6 to J1A through J4A (see diagram) on the main Acc-8D board, or through discrete wiring that connects Terminal Block 2 (TB2) on Option 6 to the Terminal Block on Acc-8D or Acc-8P. For Acc-8P, this is the only connection choice since J1A through J4A connectors are not available. For Acc-8D, either discrete wiring (through TB2), or cable wiring (through JENC1 to JENC4) should be used. The power for the PMAC half of the board comes through this connection as well.
