The supply line for each 1/4 J6/A is protected by a solid state circuit breaker (PTC Fuse)
rated for 1 amp. You should treat each 1/4 J6/A as an individual, and not cross the outputs or
supply lines from one 1/4 J6/A to the lines from another. Doing this won’t cause any damage,
but can reduce the protection for the outputs that the circuit breakers normally provide. A LED
and resistor on each 1/4 J6/A between the ground (pin #1 brown) wire and supply (pin #2
red) wire can act as an indicator which is lit if the circuit breaker is OK. The resistor should be a
value between 2.2 Kohms and 4.7 Kohms.
There is one adjustment on the FSK/RTU for setting the maximum analog voltage to be out-
put. This sets the gain for the Digital to Analog (D/A) converters on the board. To set it, pick any
output and set the minimum and maximum scaling to their minimums and maximums through
the configuration screen. When you send a full scale output command to this output, you
should then be able to adjust it for 10.00 volts using R11. The adjustments for the endpoints
on each of the 16 outputs are normally individually set through the setup screen software.
