Ouput Numbering

[Warby]

I have a system with 2 slaves. I cannot seem to get OP1 to activate on the third (2nd Slave) Board to work. is this op33 even if we are using LEMs without OP\'s?
It is just turning on a sounder which is working on the other boards and if i connect the output to 0v it works so all cabiling is correct.
TIA

This could be related to a known problem which is fixed by a Slave firmware (unreleased as yet)
I will send you the firmware file by email as we would like to see if this fixes your problem
