14 Chapter 2 - Controller Jumper Settings
Selecting the Data Transmission Rate
The E271-2200 and E271-2210 communicate with the host computer through a
serial port. Set the data transmission rate of the controller to match that of the
computer's serial port. Jumpers J0 and J1 control the baud rate as follows:
Baud Rate J0 J1
9600 none none (shipped setting)
2400 installed none
1200 none installed
300 installed installed
19200 ----cross connected----
The defaults for the other communication parameters are 8 data bits, 1 stop bit,
and no parity.
A software command may also be used to select a wider range of data transmission
rates and other communication parameters. All communication parameters can be
saved in NVRAM as a power-on default. See the Parameter command, page 95,
for details.
Selecting the Data Format
The E271-2200 and E271-2210 controller touch coordinate output may be either
ASCII characters or binary data. Jumper J2 controls the format, in combination
with the emulation mode jumpers J10 and J11 (see page 16). For details of the
standard Touch packet, see page 102. For other formats, including emulation
modes, see Appendix A.
If you are using Elo driver software, J2 must not be installed.
Format J2
Binary not installed (shipped setting)
ASCII installed
ASCII format is useful in troubleshooting installations with a dumb terminal or
modem software in local mode. Binary mode is more efficient for communication
with driver programs.
A software command may also be used to select a wider range of data formats.
The data format can be saved in NVRAM as a power-on default. See the Emulate
command, page 80, for details.
