5.2 Connectors
Connectors are similar to the RTK Base Station. See section 4.2 for information on the connectors.
5.3 Electrical Specification
Make sure that your intended power supply for the RTK Transceiver does not exceed
the voltage limits of 12 – 24 VDC in order to prevent malfunction or damage to the
device. A protective fast fuse (10A) is mandatory for the external power supply.
Pinouts and voltage ratings for the POWER/SERIAL and DATA/POWER OUT connectors are set out in the table
below.
