Multiple Unit Connection
The PPX power supplies can have up to 31 units daisy-chained
together using the 8 pin connectors (IN OUT ports) on the rear
panel. The first unit in the chain is remotely connected to a PC
using GTL-260 (RS485 cable with DB9 connector).Each subsequent
unit is daisy-chained to the next using a RS485 local bus.
Each unit is assigned a unique address and can then be
individually controlled from the host PC.
