TR-HT2xx LED Controller - User Manual
The following pulse width and restrictions apply, whether a triniti chip is
connected or not:
Pulse output current Pulse width Duty cycle limit
≤ 25A 2ms 10%
≤ 30A 1.7ms 5%
≤ 35A 1.5ms 5%
≤ 40A 1.2ms 5%
≤ 45A 800μs 5%
≤ 50A 500μs 5%
13.2.4 Trigger timing
These timing assume that a single output channel is being used.
Simultaneous events on multiple inputs can cause some variation.
Typically this can vary the timing by up to 100μs for each input.
Pulse widths below 4ms are repeatable to within 1μs and are not subject
to variation even with other simultaneous events. Pulse widths above 4ms
are repeatable to within 100μs and are subject to variation.
PTT mode pulses in the following conditions have higher priority and better
timing:
Delay = 0, pulse width ≤ 4ms
Delay + pulse width ≤ 4ms and O flag not set
For example, with OP1 to OP2 all meeting the first condition:
OP1 has a delay of 6.5μs +/- 1μs
OP2 has a delay of 6.5μs +/- 1μs
The reply time of a simple Ethernet command (for example the GT
command) is around 1.8ms for UDP and 2.8ms for TCP.
In buffer mode there is a minimum delay of 20μs between the input
changing and the output changing.
13.2.5 Event codes
On receipt of a GT1 command, the TR-HTsends event messages over its
Ethernet connection when a light is connected or an error occurs. The
message format is:
Evt<channel>,<event code>
Some events are displayed on the TR-HT's front panel; these are also
shown.
