3.7. Service Connector
The service connector RJ-12 serves for short-term connections of the service cable during local adjust-
ment of MORSE router parameters. Upon attaching the connector (connecting to the RS232 link
(RxD,TxD, GND)) the router automatically switches to service mode and the module slot 1 disconnects.
Slots numbering see section Section 3.8, “View of Radio Modem”.
