RDT Radio Modem Setup
The RDT radio modems are setup to different configurations depending upon which protocol they are
required carry. The protocols currently available are the UVMS protocol, OTU protocol, NMCS2 protocol,
FP2001 protocol. It is not recommended to use the NMCS2 (or 5 byte) protocol over RDT radios unless
signal strength is exceptionally good.
Each protocol requires its own base station radio or channel.
Not all SIESPACE systems will use all the protocols. Systems which do not have any outstation equipment
connected for one of the protocols will not have any associated base station radio modems fitted.
OTU Protocol
To implement the OTU protocol the modems at the base station and the outstations need to be setup as
follows.
OTU Base Station
The base station modem for the OTU protocol requires to be fitted with at least software version "serial
V2.0" This software allows the instation to change the address and channel number of the outstation with
which it is communicating.
Power up the modem
Set all the DIP switches to OFF
Set SW1.1 = ON
Set the following switched as indicated
SW1.2 = OFF : Async Mode
SW1.3 = OFF
SW1.4 = OFF : RS232
SW1.5 = OFF : 500mW
SW1.6 = OFF
SW1.7 = OFF
SW 1.8 = OFF
SW2.1 = OFF :1200 baud
