Tutorial<br />
By generating an Ethernet trigger (“All” and “HW Trigger” button on the EN setup video window), you<br />
can see only VINIT and IRQ counters are incrementing. This is because the first four counters are only<br />
for the hardware TTL trigger.<br />
By feeding the hardware TTL trigger, you can see “Valid Trigger count,” “VINIT count” and “IRQ<br />
count” register incrementing.<br />
If you set 1ms to “Trigger Filter Noise” register and the hardware TTL trigger pulse is less than 1ms,<br />
then the trigger is ignored as an invalid signal. Only “Trigger Filter Noise count” must be incremented.<br />
However, all other counters remain the same.<br />
If you set the PRE trigger filter to 10ms but the TTL trigger has only 9ms stable PRE condition, then<br />
only “PRE Filter Noise count” must be incremented. However, all other counters remain the same.<br />
If you set the POST trigger filter to 10ms but the TTL trigger has only 9ms stable POST condition, then<br />
the “POST Filter Noise count” must be incremented. Unlike PRE trigger, “VINIT count” is also<br />
incremented, because trigger pulse is sent to CCD anyway before finishing validation of POST<br />
condition. Once FPGA invalidates the POST condition, FPGA does not generate IRQ to PowerPC.<br />
Besides “POST Filter Noise count” and “VINIT count,” all other counters remain the same.<br />
3.6.2 Firmware Upgrade<br />
In the “Properties” window, right-click on the camera icon you want to upgrade. Select “Update<br />
Firmware in Camera(s).”<br />
TABLE 1.<br />
You can update the five pieces of firmware inside the EN camera. Each piece of firmware has a<br />
distinctive extension.<br />
