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
20), 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™ Control-
ler or while troubleshooting at the controller using a
laptop 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 Figure 20. 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 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 Adapt-
ers 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.
