Radio Identification Code
A radio identification code ( RIC for short , in German radio identification number ) is a term from radio technology and is used in BOS radio to address and alarm digital radio signal receivers and sirens with digital control receivers. The transmission takes place in the POCSAG protocol. The counterpart in analog alarms is the 5-tone sequence .
construction
A RIC is a seven-digit, uniquely assigned number. The assignment is made either person-related, group-specific or vehicle-specific. Each RIC (e.g. 1234567 ) also has four so-called Sub-RICs ( sub- addresses) a - d . Thus, one RIC represents four “loops”. The alarm is always sent directly to a sub-RIC, never to a higher-level RIC. The assignment of the sub-RICs varies depending on the organization. A possible assignment could be:
(Sub) RIC | meaning |
---|---|
1234567 a | commitment |
1234567 b | Use without hurry |
1234567 c | feedback |
1234567 d | Test alarm |
Alerting
The transmission of the RIC and the message data takes place on a channel in the VHF or UHF range . Depending on the network structure and topology as well as the desired alarm speed , various baud rates are implemented in the BOS radio : 512, 1200 or 2400 baud.
particularities
In contrast to the analog 5-tone sequences, it is possible with a POCSAG telegram to send additional short texts (e.g. exact location, situation report, coordinates for navigation system) to the carrier of a digital radio signal receiver. However, the device must be suitable for this.
