Digital Setpoint Source — RS485 Network, RS232
to RS485 Converter
(TESCOM™ Model #85061)
The USB protocol isn’t networkable, so applications requiring
multiple controllers must use RS485. RS485, wired through a
converter as shown in Figure 29, allows for up to 32 ER5000s to be
daisychained in a network.
WARNING
The controller must be disconnected from the power supply before
any additional wiring or change to jumper configuration is
performed. Do not reconnect the power supply until all additional
wiring connections have been made and are properly installed.
