0x1a - Port Configuration Block - 14 bytes
This message configures the Port Assignment for Port A (Com1), Port B (Com2), radio, and
CAN bus as specified in Words 2, 3, 4 and 5.
1. Logical Assignment Definitions
B0: NCT-RTK / Diagnostic Port (Input or Output Only)
B1: Control Port (Input/Output Only)
B2: Data Port (Output Only)
B3: NMEA Port (Output only)
B4: RTCM Port (Input/Output)
B5: CMR input Port (Input Only)
B6: CMR output Port (Output Only)
B7-B11: Reserved for internal use. (Not available for users)
B12-B15: Spare
2. Logical Ports may only be assigned to 1 physical port.
3. Control and RTCM may not be assigned to the same physical port.
4. Diagnostic, Control, and Data port cannot all be assigned to the same physical port.
The logical ports are all formatted in NCT proprietary Format. The three also have
identical capabilities.
5. Port A (Com1), Port B (Com2) and Radio Port are nominally configured for input to
use NCT Proprietary input. This is true except when CMR input is assigned to a
Physical port. In that case, CMR format (and possibly RTCM) are the only formats
recognized. (RTCM can share with either NCT or CMR)
