Acc5E Unavailable, Alternatives?

What are our alternatives to address the current unavailability of the ACC 5E. The Acc5E3 appears to address the dual handwheel encoder inputs, and it appears that the 16 bit I/O channel will work for emulating the JMux connector, however, there is no 32 bit J-I/O. Is the ACC-14E still available and does it work with the PowerPMAC? Are there any more effective solutions?

Just to clarify, there was a shortage of certain components involved in building an ACC-5E, but we now have the components and can resume building these units.

 

Thank you for this update Charles. In the interim while we wait for the pipeline to fill up again, can you give me an example of how to set up MUXIO with the ACC5E3?

Here is a typical set-up for an ACC-5E3 at index 0:

Sys.WpKey = $AAAAAAAA

Gate3[0].GpioDir[0] = $ff00

Gate3[0].GpioPol[0] = $0

MuxIo.Enable=0

MuxIo.pOut = Gate3[0].GpioData[0].a

MuxIo.OutBit = 8

MuxIo.pIn = Gate3[0].GpioData[0].a

MuxIo.InBit = 0

MuxIO.PortA[0].Enable=1;

MuxIO.PortA[0].Dir=0;

MuxIO.PortA[0].AutoParityCheck=0;

MuxIO.PortB[0].Enable=1;

MuxIO.PortB[0].Dir=1;

MuxIO.PortB[0].AutoParityCheck=0;

MuxIO.UpdatePeriod=48;

MuxIO.ClockPeriod=400;

MuxIO.PortB[0].Data=$0

MuxIO.Enable=1

 

See the "Power PMAC Users Manual" in the section "USING GENERAL-PURPOSE DIGITAL I/O WITH POWER PMAC" for details.

 

Note that we will be releasing a firmware version that corrects a clocking issue with the MUXIO that allows for full transmission rates very soon:

MuxIO.UpdatePeriod=1;

MuxIO.ClockPeriod=0;
