10) Binary Format Phase Data Output on TXD2
11) Flexible input voltage levels of 3.6Vdc to 6.0Vdc with overvoltage protection in the -LVx versions,
and 6.0Vdc to 40Vdc in the -HVx versions.
12) FLASH based program memory. New software revisions upgradeable through serial interface.
1.3 Naming Conventions
The GPS 35LP Series TrackPack™ receivers are delineated with a three letter extension to designate
the operating voltage range and the serial data voltage specification.
High Voltage - GPS35-HVx designation indicates that the unit will accept a high input voltage. The
internal switching regulator will operate from a 6VDC to 40VDC unregulated supply.
Low Voltage - GPS35-LVx designation indicates that the unit is designed to operated from a low
voltage 3.6VDC to 6.0VDC supply. Operation at about 4VDC is the most power efficient mode of
operation for the GPS35LP receiver. The unit is protected if a high voltage is inadvertently applied
to the input.
RS-232 Serial Data - GPS35-xVS designation means that the two bi-directional serial data ports
are true RS-232 ports conforming to the RS-232E standard.
CMOS Serial Data - GPS35-xVC designation means that the two bi-directional serial data ports
use CMOS output buffers. The input buffers will accept either CMOS(TTL) voltage levels or RS-
232 voltage levels. This configuration is adequate for communicating directly with serial devices
over short cable lengths (less than 20 meters).
