RS232 EXTERNAL CONTROL
The X300 software includes external control via RS232 (rear connector) and provides two enhanced
features:
Files can be created and written into on the X300 hard drive. The files can also be read back.
The X300 can be controlled via Commands. This allows many playback and recording functions
to be carried out by an external device.
These two features are enabled under the SETTINGS > EXTERNAL EQUIPMENT > GSM / REMOTE
SETTINGS menu by changing the RS232 setting to a BAUD RATE e.g. 115,200.
Baud rates of 2400, 4800, 9600, 14400, 19200, 38400, 57600, 115200 can be selected. The external
commands operate over RS232 port 1 on the rear of the unit. This port is also used for GSM modem
control. GSM control cannot be performed at the same time as external control.
Connect the X300 RS232 port to a PC using a serial cable. Some modern PCs do not come with a
serial port, you can however use a USB Serial Adaptor. Two adaptors that we have tested here are:
NEWLink
– www.newlinkproducts.co.uk
FTDI - FT232R
– www.ftdichip.com
The COM port number will vary depending on your PC and which cable you have. For example on a
laptop the NEWLink cable was assigned COM10.
A simple test to check connectivity between PC and X300 you can try following with a Telnet client (e.g.
Putty, Termite);
Telnet (port 23) to 10.0.0.200 (default X300 IP)
Enter the username; user01
Enter the password; PASS01
