PORT 2
Port 2 provides the second asynchronous channel with a simple handshaking
capability (only RTS and CTS). The baud rate for Port 2 can be set to 9600, 19200, 38400,
57600 or 115200 bit/s. Port 2 is the default port for using the M2M System Protocol.
However, if Port 1 is configured to use the M2M System Protocol, Port 2 cannot be used
for anything.
Note: A special RJ45-DB9F cable is required in order to connect the device to the PC. The cable is
supplied in the package.
4.3.3.
PORT 3
Port 3 provides the third asynchronous channel with no hardware handshakes. The
baud rate for Port 3 can be set between 1200 and 115200 bit/s.
Port 3 can be used to control external device by Java application. Also it can be
software configured to use with GPS.
Note: A special RJ45-DB9F cable is required in order to connect the device to the PC. The cable is
supplied in the package.
