ROBERTS GORDON® ULTRAVAC™ CONTROLLER INSTALLATION MANUAL

5.4 Direct Connect

For local viewing of system status and settings of any controller, a portable PC can be connected. Using the 9 pin adapter provided, (See Page 24, Figure 17), you may wire from your computer serial port to the RS-232 direct connect port on the control board via standard 4-wire phone cable. For identification of the RS-232 direct connect port, see Page 8, Figure 2. This can be useful when a PC is in close proximity to any ROBERTS GORDON® ULTRAVAC™ Controller or while troubleshooting at the controller using a lap- top PC. This type of connector should not be used if the phone wire is more than 50’ (15m) in length.

Plug one end of the phone cable into the RS-232 direct port, plug the other end into the adapter shown in on Page 24, Figure 17. Plug the adapter into a 9- pin serial port on your computer.

If a PC does not have a serial port, but does have a USB port, purchase of a USB to Serial Converter is required.

A USB to 9-pin Serial Cable will allow connection between the RS-232 device (ULTRAVAC™ Control Board) and the USB port on the PC. The USB to serial RS232 DB9 Cable Adapter will be used in con- junction with the PC Connection Cable Package (P/N 10080410). USB to Serial RS232 DB9 Cable Adapters can be purchased at a local computer store or on the internet for $20.00 or less. The converter should come with drivers and should draw power directly from USB, requiring no additional power adapter.
