[QUOTE="persjere, post: 605, member: 199"] Thanks for the response. I tried three wiring configurations. The first was based on the outdated manual, with the DC voltage supply in series with the load. In the second configuration, I just added a fixed 250-ohm resistor across the fourth output to try the signal with a passive device. I noticed an excessive voltage across the resistor (something like 19V) when doing so. The final configuration was wiring all the signals without the DC supply in the loop. The final configuration worked as described in the previous post. The only thing that I can think of that would have damaged the 4th output is if I inadvertently touched the resistor's leads together, thereby shorting out the load. [/QUOTE]
