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.

NOTE

The RE-S1 simply extends the operational range of
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.

RX/TX LED

Figure 1-2. RE-S1 Receive/Transmit LED

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.

Radio Modem Antenna Port and
Antenna

A spread spectrum reverse TNC radio antenna is required to receive/
transmit a radio signal. The antenna connectes to the antenna port on
the end of the RE-S1.

Configuration and
Usage

Once the RE-S1 is configured, it simply needs to be connected to a
power source to begin operating.

Installing Modem-TPS

Modem-TPS is a configuration program for the radio modem board
inside the receiver. Modem-TPS is available from the TPS website or
on the GPS+ CD.

Computer requirements for Modem-TPS are: Windows® 98 or newer
and an RS-232C port. Use Modem-TPS version 2.0 or newer to
correctly configure the RE-S1.

1. Navigate to the location of the Modem-TPS program and double-

click the Setup.exe icon.

2. Keep the default installation location or select a new location.

Click Finish (Figure 2-1).

To uninstall Modem-TPS, use the Start menu on your computer:

Click StartProgramsModem-TPSUninstall Modem-
TPS, and click Yes at the prompt. Then click OK when the
uninstall completes.

Configuring the RE-S1 as a
Repeater

After being configured as a repeater, the RE-S1 will pick up any radio
signal on the same channel and forward it to another radio modem.
All modems connected to the repeater must use the same protocol and
channel.

1. Connect the power cable to the RE-S1 and to a power source.

2. Using the RS-232 serial cable, connect port A of the RE-S1 to a
computer.

3. Open Modem-TPS and click Connect.

4. Select the protocol: FH915 Plus.

NOTICE

The Base, Rover, and Repeater must use the same
protocol.

5. Select your location: United States or Australia.

6. Select the operation mode: Repeater.

7. Select the output power: 1W or 250mW.
