Radisys EXM Bus Components

Third-party add-in card vendors design and market additional types of EXM modules including motion controllers, SERIPLEX and SERCOS controllers, and LonWorks interfaces.

I have manuals for everything BUT the EXM-15/15A SERCOS controller. All files are in this directory. Not every file is linked.

Note: Due to what turned out to be a happy coincidence, we have the User documentation and C files for the Automated Production Controls (APC) SERIPLEX card, part number SPX-EXM-INTF -AND- the EXM-15 Runtime. -LFO

Some manuals date from 1992 (maybe 1990 on a few). So, they might be a bit outdated for modules made in the mid 1990s. Also, the version of Word used for the early manuals is Word 2.0, which is right out if you are using Word 2003. It requires adding a registry value to allow Word to open the old file...

EXM is a mix between ISA and VME. Thankfully, most modules act as ISA cards to any operating system. So you could probably install using common drivers and it should work. Most EXM do not have specific drivers, but there are a few based on old chips dating back to 1989 or so, and they may lack support from more modern operating systems.

One EXM of note is the EXM-13A, based on the NCR / Symbios Logic 77C22E+... We do have Radisys drivers, but that chip is shrouded in mystery... NT4 does have ncr77c22.sys, which MIGHT work, but I do not know the color depth.

Notice: I have NO personal experience with any Radisys EXM related system or components. All these files were retrieved via Internet Archive and were re-named to a shorter format. To me, there can only be one period in a file name, or you may get odd problems with web pages...

Use of any of the files or information on this page is AT YOUR OWN RISK. If you want a guarantee on this stuff, seek out any repair / service company that supports EXM / EPC devices.

If you have any files or experience with these devices, please reach to Louis Ohland.

Joe Oakden got an APC SPX-EXM-INTF running again (In a Biscuit factory, yum! -LFO).

There are four of these lines, but only two use a SERIPLEX module. The other [SERIPLEX] line had been turned off for the past three months and guess what... the battery had gone flat on this machine too!!

Luckily I managed to get the SERCOS card data from the two running lines and then got lucky guessing the SERIPLEX card. I got the ID from the attached manual and got lucky making a couple of educated guesses on the dual port RAM address.

When I was trying to set the correct base address for the SERIPLEX card I initially tried a base address of 0xD000 (as per the C example in the manual) and this ended up disrupting the SERCOS card so they must both operate by reading and writing to dual-port ram. I then set the SERIPLEX base address to 0xE000 and all worked.

SERCOS card ID: F0, in this configuration, OB1: 10 and OB2: 1C

Which doesn't quite tie in with what I expected! Maybe those settings could help someone [with a SERCOS] but I'm afraid I'm not sure exactly what they relate to!

Ed. My [Forlorn] hope is the SERIPLEX module is kinda like the SERCOS module. I have not found any documentation on the EXM-15x, so Joe scored on some good stuff. -LFO

Radisys EXM Compatible Modules / Devices

EMC-FDM (FDC, floppy, DE9 serial, DB25 parallel)
   EMC-FDM Manuals

WD37C65CJM Limited to 500Kb/s data rate by 16.0 MHz osc? Supports power down mode feature, standby ICC = 100 uA max.

Parallel port direction is OUTPUT for printing -OR- INPUT for scanners. Maybe. The TL16552FN is capable of Bi-Di, so this might be OUTPUT for compatible, INPUT for Bi-Directional (PS/2).

Parallel Port can use 378h / Int 7 (LPT1?) or 278h / Int 5, or disabled.
COM port can use 2F8h, 3F8h, or 2E8h. IRQ 3, 4, or 9.

Note: Only one floppy drive controller per system can be enabled at any one time. If the EMC system requires an EXM-16 or an EXM-MX running with the EXM-FDM, disable all but one floppy drive.

Port Conflicts
Avoid interrupt and address conflicts due to multiple serial or parallel ports with the same address or interrupt. Be sure to either disable unused serial or parallel ports, or set them to a value that does not conflict with other ports in the system.

Note that in general attaching a mouse to a serial port only works on COM1 or COM2.
