APPENDIX D
Single Amplifier Configuration with N6143/N6081D Controllers
If operating in single amplifier mode, the remote interfacing becomes easier to provide. A
simple RS-485 link is required between the amplifier and the controller to give full func-
tionality. The dual amplifier controller (N6143) can still be used in this set-up as it is fully
configurable to either single or dual amplifier mode of operation. The N6081D is a low-cost,
single amplifier controller that also provides the amplifier parameter display (it uses the low
voltage DC supply from the amplifier, so it does not require a mains power connection).
Examples of the interface wiring for this method of control are as follows:
