I set the SYNC frequency (the frame rate) for the H1 ITMX HWS to 1Hz rather than the default 57Hz. This was done by accessing the serial port of the camera, making sure the frame rate was set to 1Hz and then entering the command wus
to "write user settings" to the camera.
I confirmed this was working by rebooting the camera and verifying that the frame rate returned to 1Hz.
See the attached screen capture of the command window I used to do this.
(I also turned off the HWSX SLED).
