After installation of the LAZ 5100 please follow this procedure for setting into operation the first
time.
No. Item Result
1. Installation check
1.1 Main supply (X3)
1.2 Transducer (X1, X2) – cable screening, cable laying
1.3 Printer (X7) – max. cable length 5 m
1.4 NMEA – Output (X8) – RS 422
1.5 NMEA – Input (X4) – RS 422
1.6 Start / Stop – Output (X8)
1.7 NMEA – Output (X6) – RS 422
2. Setting into operation
2.1 Disconnect Printer, NMEA - Input and Output
2.2 Only Main Supply and Transducer connected
2.3 Switch „ON“ the unit
2.4 Check and do basically settings

- draft, trim
- NMEA - Interface (4.800 baud, 8N1)
- date and time
2.5 Check the function of the unit
- depth recording
- LC - Display
