Thanks for the response! Are there any non RS-232 options, such as RS-422, RS-485, canopen, etc?

I am working on a project with a power pmac cpu and a variety of cards. We have some serial devices we need to interface with the delta tau (two way communication). We have up to 6 twisted pairs to use for the physical layer and the link will be roughly 60 meters long. Has anyone in the delta tau community worked on similar problems? What serial communication solutions does delta tau offer? At this time, I have considered a ACC-72E card. Is this a good solution? Brett

What exactly does MacroControllerInit do? We are currently working on an issue that is solved by combinations of MacroControllerInit and MS$$$0. We are wondering what MacroControllerInit does to hopefully give us a hint why and how it is solving our issue.

We are using a Power PMAC CPU main rack that contains a Acc5E card that talks (over fiber) to a remote station with a 16-Axis Macro CPU. The remote station with the 16 axis macro cpu has 16 axis, 4 axis per each of 4 ACC-24E2A cards. We are using "AmpEnable(int)" and "AmpDisable(int)" from c routines operating in the servo interrupt and the realtime interrupt. These functions are included in RtGpShm.h but they are not documented. AmpEnable works as far as we can tell. However, issuing AmpDisable will cause the encoders to function incorrectly. Additionally, AmpDisable can cause the MacroStation itself to become unresponsive. As a temporary work around, we have found "MacroControllerInit" will clear the errors. We want to understand this issue better. What exactly do AmpDisable and AmpEnable do? Do they have conditions around when they can be called? For a macro system using an Acc5E card with a 16 axis macro cpu card, what firmware version should be on the Acc5E card and what firmware version should be on the 16 axis macro cpu card? Are there equivalent commands we could use in place of AmpEnable/AmpDisable? Are the AmpEnable/AmpDisable functions compatible with a macro station? If not, what functions should we be using?
