5.2 RS-485 Converter for Central Controller

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 21, Figure 14 and see Page 25, Section 5.5

FIGURE 14: RS-485 PC Connection

For communication cable requirements see Page 12, Section 3.3.5.

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. See Page 25, Section 5.5. This allows multiple controllers to be controlled from a PC through a single communication package at the central controller.
