Important note to users of ComPact Dual Input models

Because of a bug in firmware revisions S to 31, the DC input will have high current draw during startup.  This is fixed by upgrading the firmware to revision 32 or higher. It is highly recommended to upgrade the firmware on all ComPact Dual Input units.  Please note that this bug is only present in Dual Input models, not in any other models.

Models affected:

More information is provided in the Technical Reference and White Paper – ComPact Dual Input – High startup currents

Firmware 32 (part of the ComPact Config Utility) and updated Technical Reference is included in download “ComPact Documentation and Support Software” below.  To upgrade the firmware, you also need the ComPact Communication Kit. If you do not already have this kit, please contact Comrod.

Remote control software

Comrod Power has remote control software called ComrodPowerSupport that customers can download and execute, which will give Comrod Power remote control access. This can be used for training/demonstration purposes.  When ComrodPowerSupport is started, it looks like the image shown.
