Factory Default Settings for pcb A1:

S1,S2,S3 are used for computer interface.

They have been set up at the factory as follows.

Address = “A”

BAUD =  9600

{} message delimiters

Check Sum check byte returned

No parity

RS485 mode

Ignore bad Checksum

No CR or LF returned

Termination resistor not engaged

Therefore, 7 bit words.

S4-1 “Off” for 1:2 operation.

S5-1: “Off” for normally open fault inputs. (closure for a fault)

S5-2: “Off” ignore closure fault inputs.

S5-3: “On” Monitor amplifier current levels for faults. 

Factory Settings for pcb A3:

The DNL-5 assumes that all amplifiers draw less than 325 mA.

Therefor all Jumpers on A3 (The top analog pcb above A1 (main pcb)) are positioned accordingly.

Delta V set at 0.6 volts.

The “2.5V” potentiometer settings were set with a current draw of 240 mA.
