You can stream other inputs besides the analog inputs of your LabJack. This is done by specifying special channel numbers when doing LJ_ioADD_STREAM_CHANNEL. The important part here is that even though the LabJack is actually streaming something other than an analog input, you MUST specify A to D for the I/O Type when creating your DAQFactory Channels to receive the data.
The available channel numbers are slightly different for each LabJack and listed here for your reference. Please see the LabJack device documentation for more detail:
U3:
193 EIO_FIO
200 Timer0
201 Timer1
210 Counter0
211 Counter1
224 TC_Capture0
225 TC_Capture1
226 TC_Capture2
227 TC_Capture3
UE9:
193 EIO_FIO
194 MIO_CIO
200 Timer0
201 Timer1
202 Timer2
203 Timer3
204 Timer4
205 Timer5
210 Counter0
224 TC_Capture0
225 TC_Capture1
226 TC_Capture2
227 TC_Capture3
227 TC_Capture4
227 TC_Capture5
227 TC_Capture6
You may notice that in DAQFactory, we have multiple TC_Capture channel numbers, where the LabJack documentation only lists one. This is to allow you to stream the high order word of multiple timers and counters and keep the data separate in separate channels. Internally, they are exactly the same, so you have to specify the appropriate TC_Capture immediately following its Timer or Counter channel #. In other words, to read the entire 32 bits of Timers 0 and 1, you'd do:
AddRequest(0, LJ_ioADD_STREAM_CHANNEL, 200, 0, 0, 0)
AddRequest(0, LJ_ioADD_STREAM_CHANNEL, 224, 0, 0, 0)
AddRequest(0, LJ_ioADD_STREAM_CHANNEL, 201, 0, 0, 0)
AddRequest(0, LJ_ioADD_STREAM_CHANNEL, 225, 0, 0, 0)
