Driver - Spread Spectrum Radio
Rx Spread Spectrum Radio
Reads diagnostic information from a MaxStream XTend spread spectrum radio.
Comment: A 12-character description.
RTU # (1-255): Address assigned to the spread spectrum radio. Data returned from the radio is stored in
network registers corresponding to this address.
Destination Register: (#R1 to #R2045) Specified as a local register but indicates the first network register to
begin storing radio data from. The following data is returned (where #Rx is the configured Destination
Register):

scription
Register
Range
Units
Example
Board voltage #Rx 280-575 0.01 Volts 511 = 5.11 Volts
Signal strength of last
received message packet
#Rx+1 110 to 40
or 32768*
-dBm 63 = -63 dBm
32768 = Undetermined
Number of receive errors
(message packets)
#Rx+2 0 to 65535 Errors
Number of valid received
message packets
#Rx+3 0 to 65535 Successes
* Note: Signal strength returns 32768 (undetermined) when no message packets have been received since
the radio was powered up.
Communicating With A Spread Spectrum Radio
When using an Rx SS RADIO ladder block, the RTU should be configured as follows:
• First ensure that the Spread Spectrum Radio driver is supported by the type of RTU that is being used
and that the latest firmware and driver are loaded in the RTU (as detailed in protocols.pdf available from
www.cse-semaphore.com/mykingfisher)
• From Configuration, Port List set the port Type to SS_RADIO and Baud Rate to 9600 (for 9XTend US /
Australian radio) or 19200 (for 24XStream International radio). Pre Tx and Post Tx can be left set to 0.
Protocol can also be left set to Series 2. Note: port Type can be set to RS232 if the radio does not need
to be configured with an initialisation string. When using the SS_RADIO port Type, an initialisation string
can be configured by selecting the Configure button. Please ensure that the settings used for Vendor
ID, Destination Address and Hopping Pattern are the same for all radios in the network.
• From Configuration, Network List assign an address to the spread spectrum radio (this should be a
unique address in the RTU network). The network registers of this address will be used to store the
spread spectrum radio data. Set Port # to the spread spectrum radio port number and Timeout to 4000
ms.
• When communicating between RTUs using spread spectrum radios, the Timeout of the network link to
the remote RTU should be set to 2000 ms.
• Configure an RX_SSRADIO ladder block to poll the local SS radio. An example is shown below.
