Re: Struggling JMC servo alarm wiring

Hi,
no i didn`t see this before. Do you know who drawing it? the wiring in this shematic doesn`t allow an clearing/Reset of the alarm. And the max input current of the ALM ports are 8mA...that means that a Resistor of 3kOhm is needed.

Assuming you are using Schematic S14986 for the PC55? Hi Marty, is there any way to connect the turret sensors to the acorn h...
