NMEA / Barcode Device Interface Capabilities
- Two 9-pin RS-232 serial ports, PC/AT pinout.
- The Z33's PC5L has two waterproof DB-9 RS-232 serial ports (COM1: and COM2:) for communication with your PC as well as a variety of additional input and output devices such as:

NMEA 0183 output
The Z33's PC5L will send out a NMEA 0183 message, at an interval specified by you, to either COM1: or COM2:. This functionality allows the Z33's PC5L to output a GPS position to devices (i.e. digital cameras, sonar, etc.) that will accept a NMEA 0183 message. There is no need to change your instrument settings. The Z33's PC5L communications can be set to match your instrument. In the NMEA Setup screen, you have complete control over the baud rate and protocol settings.

Efficient Data Entry with Bar Code Input
Attach a bar code scanner to the Z33's PC5L and you can quickly enter data. Bar code menus can be set up in such a way that you never need to touch the PC5L keyboard.

The Z33 System package includes CMT's PC-Mapper software for comprehensive GPS project management and mapping. PC-Mapper provides functions for Mapping, Mission Planning, Batch Differential Correction, Static Point "Spread" analysis and Job Editing. The software also supports GIS layering, raster images (i.e. DOQs, DRGs, aerial photographs, satellite imagery), multimedia objects (OLE 2.0) and Microsoft® ODBC.
