For remote on-site viewing of system status and 
settings of any controller, use the RS-485 converter 
to connect a single PC (9 pin serial port) to the RS-
485 terminals on the Central Controller. This will 
allow communication between one PC and any of the 
ULTRAVAC™ controllers on the network. For RS-485 
converter wiring details 

see Page 31, Figure 16 and 

see Page 35, Section 5.5. Wiring between the RS-
485 converter to the controller should not be more 
than 400' (122 m) in length.

For communication cable requirements 

If multiple ULTRAVAC™ controllers are being used, the 
additional controllers communicate to controller #1 
through RS-485 communication wiring arranged 
in-series from one controller to the next. 

Section 5.5. This allows multiple controllers to be 
controlled from a PC through a single communication 
package at the central controller.
