Opto22 is one of the rarest companies, they made microchannel adapters which still work with current production components... As with anything from the mythical PS/2 era, you have to know WHAT works with WHAT in order to find usable stuff on flea-buy...

First, there are two main communications styles, Optomux, RS-422/485, using a DE9 serial port, and Pamux, using a 50 pin flat cable. You cannot directly hook one to the other. You have analog and digital I/O modules, which CANNOT be mixed on the same rack. Finally, the racks power requirements vary.

The AC32 and AC34 -DO- support the PB16HQ Quad I/O modules.

Now comes the Brainboards. B1, B2, B100, B200, E1, E2, and B3000 Brainboards are Optomux compatible. The E1 and E2 Brainboards have an Ethernet port and a RS-422/485 port, but the AC32 / AC34 lack Ethernet.

odtkR12a.exe OptoDriver Toolkit for mistic I/O and Optomux Compatibility: Win95, 98, ME, NT, 2k (SP4), WinXP Pro (32-bit SP2)

The OptoDriver Toolkit for mistic I/O and Optomux contains the drivers and documentation necessary for direct communication between application programs running on a PC and Opto 22 mistic and Optomux I/O systems. Applications can be developed using languages such as Microsoft C++ or Microsoft Visual Basic.

Note: Optomux users, the OptoDriver Toolkit does not support Ethernet-based brains and does not support communication over Ethernet with E1 and E2 brains. Although you can use this toolkit for serial Optomux communications with E1, E2, B1, B2, and serial B3000 brains, a newer toolkit that handles both serial and Ethernet Optomux is preferable for Windows 2000/XP systems: Optomux Protocol drivers and utilities. The Opto Driver Toolkit is useful, however, for those who have an existing Optomux application based on an older version of the OptoMWD driver for Windows 32-bit or Windows 16-bit systems.

Important: The OptoDriver Toolkit is available free of charge. To install it, however, you must supply this password: 12DROWSY98

Ladder Logic Flowchart Programming Differences and Examples

Note: The final Pamux brain board on the bus must be terminated with a TERM1 or TERM2 terminator board. A TERM2 board is identical to the TERM1 in size and function. The only difference between the boards is that the TERM2 offers lower line impedance than the TERM1. This may prove useful when using a cable that differs from recommended specifications.

B3000 Flash Firmware
If you have a B3000 brain that was manufactured after July 1998, your firmware can only be updated with a hardware upgrade. Older B3000 brains can be updated using special software.

Connecting Wire

This is the wiring between the D shell connector and the first OPTOMUX on the link.

Please note that the pin numbers are labeled on the connector.

Communicating With OPTOMUX

Before applying power to OPTOMUX Brain Board(s), set the baud rate and command protocol on the OPTOMUX Brain Board(s). The baud rate and command protocol are selected by the B group of jumpers on the OPTOMUX Brain Board(s). (Please refer to the OPTOMUX B1 and B2 Digital and Analog Brain Boards Operations Manual, Form 203 for additional information.)

For the checkout, remove all of the group B jumpers from one OPTOMUX Brain Board and disconnect all other OPTOMUX Brain Boards on the network. This will select a baud rate of 300, the four-pass protocol, and an OPTOMUX address of 255.

Connect the D shell connector to the AC34 card and turn on the power to the IBM PS/2 and the OPTOMUX. To test the link, enter the IBM BASIC interpreter and type in the following program. The underlined part of line ten must be changed to COM1 when using the AC34 card as communications port one.

10        OPEN "COM2:300,N,8,1,RS,CS,CD,DS" AS #1
20        PRINT #1,°>FFACD"
30        INPUT #1,B$
40        PRINT B$

When running the program, both the receive and transmit LED's on the OPTOMUX will flash. The IBM PS/2 will display the AFFACD on the screen. If nothing is displayed, verify that all the wiring has been done correctly.
