APPENDIX B
REMOTELY MANAGING THE SYSTEM THROUGH AN RS-232 SERIAL INTERFACE

smarttech.com/kb/170911

This appendix includes detailed instructions on how to set up your computer or room control

system to remotely manage the SMART Board interactive whiteboard system settings through an

RS-232 serial interface.

Connecting a room control system to the ECP

By connecting a computer or room control system to the 4-pin connector on the ECP, you can

select video inputs, start up or shut down the interactive whiteboard system and request

information such as projector lamp use, current settings and network addresses.

NOTE

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 included with

SMART UF55 projectors.

Serial interface settings

The projector’s serial interface acts as a Data Communications Equipment (DCE) device, and its

settings can’t be configured. You must configure your computer’s serial communication program or

the room control system’s serial communication settings with the following values:

Setting

Value

Data Rate

19.2 kbps

Data Bits

Parity

None

Stop Bits

Flow Control

None

NOTES

Asynchronous mode is disabled by default in the projector.

All commands should be in ASCII format. Terminate all commands with a carriage return.

All responses from the projector are terminated with a command prompt. Wait until you

receive the command prompt indicating that the system is ready for another command

before you proceed.

The room control feature of the projector is always on.
