Topcon Euro 112T Board Specifications

Based on the small Eurocard format (112mm), this provides tracking of 20 satellites of dual frequency GPS and GLONASS and can be password upgraded to:
• GD mode (L1 + L2 GPS)
• GG mode (L1 GPS & GLONASS)
• GGD mode (L1 + L2 GPS & GLONASS)

The Euro-112T draws only 2.7 watts of power and provides all of Topcon’s exclusive and advanced GPS+ features. It includes USB (12Mb/s), Ethernet (10Mb/s), four high speed RS232 serial ports, and on-board power supply. You won’t find more accuracy in a larger board.
