9.2.2.

GPS Serial Port (NMEA)

This port is carrying out the GPS navigation data in NMEA 0183 format. The default
configuration is 4800 bps, 8, n, 1

It is available on the following pins:

BALL

NAME

DESCRIPTION

TYPE

F8

GPS_TX

GPS TX Data (NMEA)

CMOS 2.8V (GPS)

E10

GPS_RX

GPS RX Data (NMEA)

CMOS 2.8V (GPS)

GPS RX Lines and TX lines may need a dual supply isolation buffer like an FXLP34 to avoid
CMOS high states while in POWER SAVING.

9.3.

RS232 Level Translation

In order to interface the Telit GE/GC864-QUAD V2 AND GE864-GPSwith a PC com port or
a RS232 (EIA/TIA-232) application a level translator is required. This level translator must



invert the electrical signal in both directions



change the level from 0/+3V to +15/-15V

Actually, the RS232 UART 16450, 16550, 16650 & 16750 chipsets accept signals with lower
levels on the RS232 side (EIA/TIA-562), allowing for a lower voltage-multiplying ratio on
the level translator. Note that the negative signal voltage must be less than 0V and hence
some sort of level translation is always required.

The simplest way to translate the levels and invert the signal is by using a single chip level
translator. There are a multitude of them, differing in the number of driver and receiver and in
the levels (be sure to get a true RS232 level translator not a RS485 or other standards).

By convention the driver is the level translator from the 0/+3V UART level to the RS232
level, while the receiver is the translator from RS232 level to 0/+3V UART.

In order to translate the whole set of control lines of the UART you will need:



5 driver



3 receiver
