Receiver Description
Bluetooth Antenna
A coaxial female connector (reverse SMA type) allowing you
to connect a Bluetooth antenna for wireless communication
with a field terminal or other device.
Cellular Antenna
A coaxial female connector (SMA type) allowing you to
connect a cellular antenna. A cellular antenna is required
when the HDS800 sends or receives RTK or differential
corrections data via its internal cellular modem (GSM).
Take care not to swap the Bluetooth antenna and the cellular
antenna. The picture below shows where the shorter and
longer antennas should be connected.
USB Host & Device
A nine-contact female connector (Fischer type). Depending
on how it is configured, the USB port can be used in two
different ways:
1. For a USB host, such as a mass storage device using
optional device cable P/N 702104.
2. For a USB device allowing HDS800 to be seen as a disk
from the computer connected to this port. In this
configuration, files can be transferred between the
HDS800’s internal memory and the computer using the
USB cable provided (P/N 702103).
Display Screen
The display consists of a 128 x 64-pixel, 1.5-inch
monochrome yellow screen using organic LED technology
(OLED).
Used in conjunction with the Scroll button, the display screen
allows you to view different pages of information. See
