KB01129 - Control system lock ups with CLSO-601

SKU affected: AT-UHD-CLSO-601

Scenario: A control system is sending a “PWON” command via telnet or RS232 (or any IP-based control system) which is causing the AT-UHD-CLSO-601 to freeze up (no response via RS232)

Troubleshooting: Test if the unit responds to front panel commands. If so, there might be a network or cabling issue preventing IP control or a cabling issue preventing RS232 from passing. If unit doesn’t respond to front panel commands, try performing a power cycle of the switch and see if control is restored. If removing the control system connection allows the 601 to work correctly, this is a sign that there may have been a control issue such as too many commands send in a short time period (a few milliseconds apart) and thus adding a delay of 100ms between each command is a solution.

Solution: In case the issue is not related to commands being sent in a short time period, there is a BETA firmware (1.2.05) that addresses this issue and all subsequent firmware versions will have this fix implemented. Please see attached file with BETA firmware, otherwise check the firmware tab for the most recent firmware.

CLSO-601 Beta Firmware is attached.
