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

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.
