HD9625DSK Instruction Manual
2.3.7. PGM BUS LOCK
This button toggles the lock status of the output video. Transitions will be enabled while the
PROGRAM BUS is locked, however button presses on the PROGRAM BUS will be ignored.
2.3.8. BYPASS
Pressing the bypass button will force the relay on the input of the I/O module to disengage. This will
route the incoming video directly out through the relay bypass output connector. The LED above the
Bypass button illuminates to indicate that the unit is in manual Bypass. Pressing the button once
again energizes the relay allowing the input video to pass through the unit. The bypass relay will
disengage if the frame loses power preserving the video output stream. Note: Only the bypass output
connector is bypass relay protected, all other outputs will not function on a power loss.
