ROBERTS GORDON® ULTRAVAC™ CONTROLLER INSTALLATION MANUAL

SECTION 5: COMMUNICATIONS

One ROBERTS GORDON® ULTRAVAC™ Controller per building (called the "central controller) must have equipment for remote communications to a PC. This equipment consists of either a modem chip, an RS- 485 converter, or a TCP/IP communications module.

For remote on-site and off-sitecontrol and system status viewing the central controller (controller #1) is fitted with a modem chip. See Page 20, Section 5.1.

If only remote on-sitecontrol and system status viewing, two controller communications interface devices are available: an RS-485 converter or a

TCP/IP communication module.

An RS-485 converter is installed at a single PC, this PC can interface with any controller on the network of ULTRAVAC™ controllers. The RS-485 converter at the PC is wired directly to controller #1 using

shielded twisted pair communication wiring. See Page 21, Figure 14.

To interface with ULTRAVAC™ controllers through a Local Area Network (LAN), a TCP/IP Communication module is installed at controller #1. Controller #1 is wired to the LAN by an Ethernet cable. See Page 22, Section 5.3. Any computer on the LAN that has ULTRAVAC™ software installed can communicate with the controllers. Appropriate precautions must be taken to protect the Ethernet wiring from any possible electrical interference (noise) caused by surrounding machinery or equipment.

If multiple ULTRAVAC™ controllers are being used, the additional controllers communicate to controller #1 through communication wiring arranged in-series from one controller to the next. See Page 25, Section 5.5.

5.1Dedicated Phone Line for Central Controller Modem

The Central Controller is fitted with a modem chip. To use the modem, the controller must have a phone line for modem communications. Install a phone line near the location of the Central Controller. The phone cable is plugged into the phone connection in the corner of the control board. See Page 20, Figure 13. If the modem option is not used for everyday commu- nication to the controller(s), it can still be plugged into a phone line for troubleshooting or programming assistance. Contact your local Roberts-Gordon inde- pendent distributor for details.

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.
