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

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.

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

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

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.

System Setup

Before using the MR-2, you will need to connect the necessary cables and antenna(s), and install the Topcon
software, which enables you to configure the receiver. This chapter describes how to set up your new receiver.

Cable and Antenna Connections

The MR-2 receiver is designed to use either a serial cable or Ethernet cable for full operation. The cable and
antenna setup for serial and Ethernet is described below.

Serial Cable Setup

Step 1: Power the Receiver

You can apply power to both ports at the same time. The receiver draws power from the port with the higher
voltage. If both voltages are the same, power will passively switch between both ports. The switching happens
within operating range, and causes no drop in power. The receiver will work without interruption.

1. Mount the receiver to a suitable hard surface where the LED is visible and the ports are accessible. See also
“Mounting the Receiver” on page 9.

2. Connect the supplied serial cable harness to the power/communication port (Figure 5).

Figure 5: Connecting the Serial Cable Harness to the Receiver

3. Connect the adapter cable to the power connector of the cable harness, as shown in Figure 6.

4. Connect the other end (SAE connector) of the power adapter cable to a 9-36 VDC power supply unit with
an SAE connector, as shown in

Figure 7: Power Adapter Cable to Power Supply Unit

Figure 7.

You can also create a custom cable to connect a 9-36 VDC directly to the 3-pin Deutsch connector on
the break-out harness.

5. Verify the power supply is on and supplying power.

6. Make sure the MR-2 LED is lit solid, which indicates it is receiving power.

System Setup

Step 2: Connect to a Computer or Display Unit and RTK Correction Source

1. Connect the COM1 serial port connector on the cable harness to the serial port on the computer or display.

2. (Optional) If the MR-2 is RTK enabled, connect the COM2 serial port connector to the serial port of the RTK
correction source.

Figure 8: Cable Harness – COM1 and COM2 Serial Ports

Step 3: Connect a Single Antenna

To connect a single external antenna for precise positioning:

1. Mount the GNSS antenna on a rigid surface.

2. Connect the antenna cable to the primary antenna connector circled in red in Figure 9.

3. Make sure the antenna cable is connected to the antenna.
