Connecting your room control system to the
SMART UF70 projector
By connecting acomputer or room control system to the RS-232 serial interface of the SMART UF70
projector, you can select video inputs, start up or shut down your interactive whiteboard system and
request information such as projector lamp use, current settings and network addresses.
Pin configuration on the projector’s RS-232 connector
The following table provides the pin configuration on the SMART UF70 projector. This pin
configuration follows a three-wire connection so that a straight-through male-to-female RS-232 serial
cable connects to the projector’s serial interface in the following arrangement:
Pin number Projector’s female RS-232 connector
2 Transmit
3 Receive
5 Signal Ground
N O TE
On projectors with the RS-232 connector labeled Control 9v (rather than Control), pin 1 functions
as a +9V DC power source only for use with older model ECPs such as the ones shipped with
SMARTUF55 projectors.
Serial interface settings
The serial interface of the projector acts as a Data Communications Equipment (DCE) device and its
settings can’t be configured. You must configure your computer’s serial communication program
(such as Microsoft® HyperTerminal) or your room control system’s serial communication settings
with the following values:
Setting Value
Data Rate 19.2 kbps
Data Bits 8
Parity None
Stop Bits 1
Flow Control None
