supply
• level TTL0 or grounded clamp - battery supply
Maximal supply cable length is 3 m.
3.9. Information LED
Information LED diodes next to the supply connector:
• RF Tx — radio modem transmits RF frequency into antenna
• RS SYNC — radio modem received message header which was determined for it
• Three following LED (signal strength):
RSS -85dBm and strongerONONON
RSS -85 až -95dBmONONOFF
RSS -95 až -115dBmONOFFOFF
RSS -115dBm and weakerOFFOFFOFF
• POWER ON — radio modem is correctly supplied
3.10. Service Connector
The service connector RJ-12 serves for short-term connections of the service cable during local adjust-
ment of radio modem parameters. Upon attaching the connector (connecting to the RS232 link (RxD,TxD,
GND)) the radio modem automatically switches to service mode and the module slot 1 disconnects.
