TRDS 4001
35 / 36 User Manual Rev. 4.0 - 23/03/01
The TRDS4001/SAT Encoder version, in the chief menu, is provided with a further
option, as follows:
O) STATION SELECTION
The RDS SAT version codifier provides the messages planning with a directely
connected Pc and with a remote connection of the PC to the UP-LINK transmitter.
In this case, the several codifiers are identificated by an internal 8 bits code (from
1 to 255) in EPROM memorized; when the user wants to modify a codifier message,
he has to know the relative code.
The several codes are listed into the record "STATION.DAT", which is realized
and modified by a standard EDITOR. The record provides 4 useful fields to the
encoder identification which are separeted by commas:
1) Code, 3 numerals number (from 1 to 255). The codes more shortly than
3 numerals have to be preceded by spaces;
2) Address, alphanumeral field at most of 30 characters;
3) Place, alphanumeral field at most of 25 characters;
4) District, 2 characters field.
The supplied management program uses only the field 1 for the encoder addressing;
the other ones could contain the informations that the user considers more proper.
The only bond to respect is NOT EXCEED the presetted characters limit. Into the
record STATION.DOC, two encoder could not have the same code.
