Introduction

The RE-S1 is a 1W radio extension system using 915+ spread
spectrum technology. The RE-S1 can be used to enhance the
following survey-related systems:

• As a stand-alone repeater to increase the range between a Base
and Rover in spread spectrum systems, such as with the GR-3 or
HiPer Lite+ GPS systems.

• As a transmit/receive external 915+ radio for any Base system,
such as with the GB or Legacy series GPS receiver.

Obstructions—such as buildings, terrain, trees, etc—greatly affect the
usability and range of a spread spectrum system. The RE-S1 provides
radio repeater capabilites and increase the operational range and
effectivity of the system in unfavorable environments.

The RE-S1 simply extends the operational range of

NOTE

a spread spectrum system. It does not increase
range beyond the system’s OAF limitations.

Introduction

Getting Acquainted

The RE-S1 is a transmit/receive/repeat 915+ spread spectrum radio
modem. The RE-S1 is compatible with existing Topcon spread
spectrum radio systems (some older HiPer models may need a radio
modem upgrade), as well as Topcon base stations. Simple features
allow the RE-S1 to be easily adaptable to any situation, and make it
easy to use.

RX/TX LED

The RX/TX LED provides the following indications for the modem:

• Green flashes – modem is in receive mode and is searching for
radio link.

• Green solid – radio link established.

• Green solid with Red flash – modem is receiving.

• Red solid – modem is in transmit mode.

• Red flashes – improper configuration.

LED notes: The RX/TX LED will be solid green with a red flash

when the Base receiver is within radio range of the repeater system.
The red flash indicates the following:

• A data packet has been received from the Base.

• A data packet has been transmitted from the repeater system.

If the RX/TX LED flashes green for an extended period of time,
check the following:

• The repeater’s distance from the Base.
