Transmission GPS Data through Modem

The SD-170E supports GPS data handling. That may help your implementation for a system related to GPS. If it is not

enough for your application, received position data from the GPS module placed in an SD-170E can be reprocessed by

your own application. The ACC-515E is a GPS module for the SD-170E, which releases 11 different output data according

to the NMEA-0183 format, which can be selected by you, the available data should be processed by your application.

Received data from the ACC-515E will be released via the DB-15 connector of the SD-170E and/or transmitted to another

system through an installed modem. More detailed information for the GPS option board is given in the technical manual for

the ACC-515E.
