Communications Protocol

The arrangement of the terminal assignment data permits you to assign all inputs in a single command. The example below shows a transmission to the inverter at address Node 1 to set the Forward command, Multi-speed 1 and Multi-speed 2.

0x0000000000000001

+ 0x0000000000000004

Sum the three data strings: + 0x0000000000000008 = 0x000000000000000D
