Accessory 8D Option 6
Introduction 1
INTRODUCTION
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.
Note:
The flat cables provide only a single-ended third-channel signal to the Acc-8D.
Because of the short distance, any difference in noise immunity should be minimal.
In this case, tie the complementary third-channel signals on the main Acc-8D
board to 2.1V with the appropriate jumpers.

Connectors 3
CONNECTORS
TB1
This is a 26-pin terminal block that brings in the actual encoder signals and the power supply to the input
side of the Option 6 board. See the pin definition listing for TB1 at the end of this manual.
TB2
This is a 26-pin terminal block which may be used to feedback the optically isolated encoder signals to
Acc-8D or Acc-8P terminal block. The power supply to the output side of the opto-isolator is also
brought in through this terminal block. See the pin definition listing for TB2 at the end of this manual.
JENC1
These are 16-pin (supplied) flat cable connectors which allow convenient connection from Option 6
output to Acc-8D J1A.
JENC2
These are 16-pin (supplied) flat cable connectors which allow convenient connection from Option 6
output to Acc-8D J2A.
JENC3
This connector allows the optically coupled encoder signals for the first encoder to be fed back to the
Acc-8D through its connector J1A. Either JENC connectors or TB2 connectors should be used for
encoder feedback to Acc-8D J3A.
JENC4
This connector allows the optically coupled encoder signals for the first encoder to be fed back to the
Acc-8D through its connector J1A. Either JENC connectors or TB2 connectors should be used for
encoder feedback to Acc-8D J3A.
