Configuration - Spread Spectrum Radio

If the port type is set to SS_RADIO, selecting the Configure button will display the following options:

The spread spectrum radio uses extended AT commands to set or read various parameters.

Default String: The beginning of the initialisation string sent to the radio. When configured (ie the Default

String is not blank), the RTU automatically adds the Vendor ID, Destination Address and Hopping Pattern

commands to the end of the string and then sends the complete string to the radio in the format:

[Default String],[Vendor ID],[Destination Address],[Hopping Pattern],WR

Default Strings:

Radio Defaults <blank - no string sent to radio>

AUS/US (Point to Point): ATBR0,MT0

AUS/US (Point to Multi-point): ATBR0,MT2

International Radio AT

BR0: Data is transmitted between the radios at 9600 bps. Note: if a higher baud rate is used, the

transmission range may be reduced.

MT: Multi-Transmit mode (Australia / US only. Not required for the International radio). MT0 [default] = point

to point mode, MT2 = point to multi-point mode.

Vendor ID: (16-32767, default=13106) Sets the ID number of the Spread Spectrum radio. All radios on the

same network need to have the same Vendor ID in order to communicate with each other. It is

recommended that Vendor ID be changed to avoid interference with other radio networks. A setting of 13106

can be used to communicate with G3 spread spectrum radios (by default).

Destination Address: (0-65535, default=65535) Sets the Destination address of the Spread Spectrum

radio. All radios on the same network need to have the same Destination Address in order to communicate

with each other. It is recommended that Destination Address be changed to avoid interference with other

radio networks. A setting of 65535 must be used to communicate with G3 spread spectrum radios.

Hopping Pattern: (0-6, default=0) Sets the Hopping channel of the Spread Spectrum radio. All radios on the

same network need to have the same Hopping channel to enable them to communicate. To minimise

interference from another RTU using a spread spectrum radio, a hopping channel number that is different to

the offending radio should be used.
