Message Type 113, ULCP binary format, Digital Input/output (IO), modem ID, plus minimal GPS data
Header: 0x71 0xSS 0x06 0x00 0x00 0xNN 0x0000
Where NN is the message length - dependent on the Modem ID string length.
Message body:
| Hex | Description |
| 4 bytes | Time (based on number of seconds since 00:00:00 January 1st 1970 |
| 4 bytes | Normalized latitude (RMC latitude x 100,000) (little endian/bytes reversed) |
| 4 bytes | Normalized longitude (RMC longitude x 100,000) (little endian/bytes reversed) |
| 1 byte | Bit 7 = GPS data validity (1 = valid, 0 = invalid); Digital input state (0=off, 1=on): Bit 6 = Ignition status, bit 5 = output #6...bit 0 = output #1 |
| 1 byte | Bit 7 = input #8...bit 0 = input #1 |
| 1 to 15 bytes | Modem ID: ASCII string |
Note: ULCP binary messages should not be used for local serial report mode 1 and 2 in applications where timed message delivery is critical.
