Can I get more than 2 StartTrig and 2 REQ inputs from a PCI 6534 card ?

[kwolsen]

I have an application where I like to use one 6534 card to receive several digital inputs. The digital inputs are a clock, data and a start trigger pulse. I have 3 sets meaning that I need to receive 3 clocks, 3 start trigger pulses and 3 data inputs, all independent of each other. So, is there any way to configure the 6534 card to trigger on a pulse connected to StartTrig, then sample data on each clock but do this for 3 inputs. I'm using pattern generation in which I tie one clock to the REQ1 and another clock to REQ2 as well as connecting my start trigger pulses to StartTrig A and B inputs, repsectively. So, I've run out of starttrig and req inputs.

Can any of the all pu
rpose digital I/O pins be configured as additional REQ and StartTrig inputs or do I need another board ?

thanks

Hello;

Unfortunately, the 653x family only allows 2 different and independent handshaking groups. So, it's not possible to have three independent lines being clocked by 3 diferent clock signals.
