Getting Acquainted

This chapter describes the standard components and accessories included with your receiver.

Communication and Power Port

Both the serial and Ethernet communication connectors of the MR-2 feature a power input.

Power Input

The serial and Ethernet connectors on the MR-2 accept an external 9 to 36 VDC power source. Connect the

MR-2 to a power source to turn on the receiver. When the LED is lit solid, the MR-2 is receiving power. Disconnect

the MR-2 from the power source to begin the shutdown process. The power LED will remain on until the end of

the shutdown process (see

“Turning the Receiver On/Off” on page 19 for more information).

Com Features

•

Supports serial data using EIA RS-232C-level signals.

•

Supports baud rates of 115,200 and higher.

•

Supports RS232 RX and TX signals.

•

Supports simultaneous output of position and status data along with input of control commands and/or

differential corrections for RTK.

•

Supports CAN

•

Supports GNSS board firmware upgrades.

•

Supports input of differential RTK corrections from an external radio source.

PPS Connector

Modern synchronization and time transfer applications require a highly-reliable timing source. The MR-2 supports

a 1PPS (pulse-per-second) signal, which provides a very accurate reference source for external devices. You can

program the period, offset, edge, and time reference of the 1PPS signal using GRIL commands.

The 1PPS signal has the following attributes:

•

Amplitude (on 50 Ohm load): >=2 Volts

•

Polarity: Positive

•

Normal pulse width: 3.3 ms

Ethernet Connector

Attach the Ethernet cable to the breakout, which splits the signal to the RJ45 Ethernet port and the SAE power

port.

Antenna Connectors

Figure 2 shows the antenna connectors for the MR-2. The primary antenna connector is used to connect a GNSS

antenna for precise RTK positioning. You can connect another GNSS antenna to the secondary connector for

heading and inclination determination. For more information, see

“Step 4: Connect Dual Antennas (HD2)” on

page 14.

For complete MR-2 operation, the external antenna supports at least GPS L1C/A, L2C, L2P (Y), GLONASS L1/L2,

and SBAS (WASS/MSAS/EGNOS) signal tracking and accept voltage at +4.75 to +5.10 VDC at 0-70 mA.

Topcon guarantees performance specifications of the MR-2 only when used with Topcon antennas, such as PG-

F1 GNSS antennas.

Option Authorization File (OAF)

Getting Acquainted

Option Authorization File (OAF)

Topcon Positioning Systems issues an Option Authorization File (OAF) to enable the specific options that

customers purchase. An Option Authorization File allows customers to customize and configure the receiver

according to particular needs, thus only purchasing those options needed.

Typically, all receivers ship with a temporary OAF that allows it to be used for a predetermined period of time.

When the receiver is purchased, a new OAF permanently activates the desired, purchased options. Receiver

options remain intact when clearing the NVRAM or resetting the receiver.

The OAF enables the following kinds of functions:

•

Signal tracking (standard L1 GPS; optional L2, signal tracking)

•

Update rate (standard 1Hz; optional 5, 10, 20, 50, or 100 Hz)

•

RTK at 1, 5, 10, 20, 50, and 100 Hz

•

RTCM/CMR Input/Output

•

2-D attitude determination

•

Advanced multipath reduction

•

Satellite Based Augmentation System positioning (WAAS/EGNOS/MSAS)

•

RS-232C (2x) connectivity

Twin Antenna System (HD2)

The MR-2 receiver includes a twin antenna system called HD2. It derives 2D attitude parameters, namely the

heading and inclination, of the baseline between two antennas mounted on a platform. For more information,

see “Twin Antenna System for Heading and Inclination Determination (HD2)” of the



B125 Integrator’s Guide

.

Visit the TPS website (or consult a TPS dealer) for a complete list of available OAF options, details,

and upgrades.

LED Indicators

The LED indicators able you to control receiver power and data recording. The LEDs display the status of the

power, Ethernet connectivity, and satellite tracking. This chapter describes the different LED blink patterns and

what they mean.

Figure 4: LED Indicators

Receiver Status LEDs

There are four status LEDs to provide you information about power Ethernet connectivity, and tracked satellites.

This section describes the color and behavior of each LED.

Power LED

The Power LED indicates whether the receiver is on or off, and to indicate the status and type of OAF loaded.

LED Color Description

When the LED is off, the receiver is off.

When the LED is blinking or solid, the receiver is

on and an OAF is loaded. See below for the types

of OAF.

When the LED continuously blinks between red,

green and yellow, a standalone positioning OAF is

loaded.

When the LED is solid green, an RTK-enabled OAF

is loaded.

Ethernet LED

The Ethernet LED indicates the status of the Ethernet connection.

Satellite Tracking (STAT) LED

There are two LEDs to indicate the status of satellite tracking. If your receiver has only one B125 board, only

the STAT LED for the primary antenna will operate (

Figure 4 on page 10). If your receiver has a second B125

board will both STAT LEDs operate. The number of blinks the LED makes indicates the number of satellites for

that constellation.

Table 5 describes the blink patterns.
