Set the Network Type and Node Address Switches
Before you install the module, you must set the network type, drop number and drop
depth using the switches at the top of the module.
The two switches at the left set the drop depth, the two at the right set the drop
number.
The following table shows how to set the switches for each mode of operation.
Depth 10 Depth 1 Drop 10 Drop 1
DCS
Master
0 0 0 0
DCS slave Drop depth
10’s digit
Drop depth
1’s digit
Drop Number
10’s digit
Drop number
1’s digit
Remote
I/O Master
0 1 0 0
For example, to configure the 56AMXN/B as a DCS slave with drop number 17,
drop depth 5, set the switches to 0, 5, 1, and 7 from left to right.
Any other settings are invalid and result in the module going into “Thumbwheel
test” mode. In thumbwheel test mode, the display shows the current switch settings.
It doesn’t go out of thumbwheel test mode until you cycle power.
In thumbwheel test mode, the 56AMXN/B initially displays “Thumb Test Mode”
on the 4-character display, displays the switch settings for 5 seconds, then resumes
displaying “Thumb Test Mode”
For DCS slave operation, if the drop number and drop depth are individually valid
but the combination results in invalid drop numbers (for example, drop number 55,
drop depth 2), the module displays an error message on the 4-character display but
does not enter Thumbwheel test mode.
