Getting Acquainted
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.
