 Serial Port Usage
* The BRX series has three serial ports: [S1/S2/S3]. S1 (Serial Port 1) is
used solely for debugging and maintenance while S2 (Serial Port 2) and S3
(Serial Port 3) may be used to connect various external devices such as GPS,
External IR receiver, Tachometers and the EMS Alert unit.
- SERIAL2 – DEVICE and SERIAL3 – DEVICE: Use the arrow keys to select
connected external device to activate.
- SERIAL2 – BAUD and SERIAL3 – BAUD: use arrow keys to select baud rate
from the following preset values: “4800/9600/19200/38400/115200”
＊ The baud rates for D-TEG products including EMS Alert unit, GPS, and
remote control is 9600.
 TACHO DATA
* The TACHO DATA settings are only accessible if either TACHO DONGSUN or
DT-STD is selected for use.
- GPS, SPEED, RPM, and SIGNAL: Depending on what data is being drawn
from the tachometer, GPS, SPEED, RPM, and SIGNAL can be activated by
using the arrow keys.
Note
1. To avoid repetitive device settings, the device selected for SERIAL2 – DEVICE will not
be available for selection for SERIAL3 – DEVICE and vice versa.
2. Since there are only two available serial ports, only two external devices can be used
at the same time.
3. Typically the EMS Alarm Display Unit is plugged into S2 and GPS into S3.
