EN Camera
Series
If you set the PRE trigger filter to 10ms but the TTL trigger has only 9ms stable PRE condition, then
only “PRE Filter Noise count” must be incremented. However, all other counters remain the same.
If you set the POST trigger filter to 10ms but the TTL trigger has only 9ms stable POST condition,
then the “POST Filter Noise count” must be incremented. Unlike PRE trigger, “VINIT count” is also
incremented, because trigger pulse is sent to CCD anyway before finishing validation of POST
condition. Once FPGA invalidates the POST condition, FPGA does not generate IRQ to PowerPC.
Besides “POST Filter Noise count” and “VINIT count,” all other counters remain the same.
3.6.2 Firmware Upgrade
In the “Properties” window, right-click on the camera icon you want to upgrade. Select “Update
Firmware in Camera(s).”
You can update the five pieces of firmware inside the EN camera. Each piece of firmware has a
distinctive extension.
