Firmware BETA firmware for OptoControl-based controllers
OptoControl BETA Firmware
This download contains BETA firmware for Opto 22 controllers running OptoControl strategies.

Beta Version Disclaimer:

OptoControl is a legacy product, which is no longer getting new features and no longer going through official release cycles. Beta versions of the firmware are made available as-is for those who need the related bug fixes.

In general, beta versions will include bug fixes since the last official release, without adding new features. This usually enhances product stability without introducing unwanted side effects. Beta versions for legacy products have been through basic testing only, and will not be formally tested.

Ultimately, the choice will be up to the user as to whether the benefit of using the beta version is worth the risk. We simply want to make the beta version available so that you have options.

Firmware M4SENET-100 Ethernet Adapter Card Firmware
M4SENET-100 Firmware
This file contains the current release of the M4SENET-100 Ethernet adapter card firmware, which includes a Telnet interface for communicating with the card.

Important Instructions
If you are upgrading firmware on an M4SENET-100 card manufactured prior to August 2003 (or a card that has firmware prior to version 5.0) follow these steps:

1. Write down all settings that you have saved to flash, for example, security settings.

2. Important: Using the Operation Code in the Status Write area of the Web pages for the card, clear flash memory.

3. Now load the new firmware, following instructions in Opto 22 form #1156, the M4SENET-100 Installation Guide.

4. Using Telnet and following the steps in the M4SENET-100 Installation Guide dated June 2003 or newer, reset the settings you wrote down in step 1 and save them to flash.

If you did not clear flash memory (step 2), Telnet will not work with your card. In that case, you must reset the card to factory defaults and then assign an IP address to it before you can reset settings. Steps for resetting to factory defaults and assigning an IP address are in the M4SENET-100 Installation Guide.
