CGS Programmer-Sequencer: 10v pulse out

CGS Programmer-Sequencer: 10v pulse out

2014-12-11 by data2action

looking to revise the sequencer/programmer to be compatible w/ 10v triggers.

for the AEP and CPO pulse outs, i'm thinking i could just exchange the places of the 2k2 and 1k resistors, and get 10v pulse outs rather than 5... likewise with the individual stage pulse outs, swap the 680r and 820r to get 10v. right so far? finally, would I need to decrease the 470k shunt from the Ext Pulse In (stage select) to ground, to account for the higher trigger voltage?

thx!

Hi Bbob,
swapping the 2k2 and 1k would work. For the 680/820 pair, you will need to find a new ratio, as swapping them does not make a large enough difference.
No changes are needed for the inputs.
