Table 3: Byte Arrangements
3.2 Abbreviated ASCII
This message format is designed to make the entering and viewing of commands and logs by the user
as simple as possible. The data is represented as simple ASCII characters, separated by spaces or
commas, and arranged in an easy to understand format. There is also no 32-bit CRC for error
detection because it is meant for viewing by the user.
Example Command:
log com1 loglist
Resultant Log:
<LOGLIST COM1 0 69.0 FINE 0 0.000 00240000 206d 0
< 4
< COM1 RXSTATUSEVENTA ONNEW 0.000000 0.000000 NOHOLD
< COM2 RXSTATUSEVENTA ONNEW 0.000000 0.000000 NOHOLD
< COM3 RXSTATUSEVENTA ONNEW 0.000000 0.000000 NOHOLD
< COM1 LOGLIST ONCE 0.000000 0.000000 NOHOLD
As you can see, the array of 4 logs are offset from the left hand side and start with ‘<’.

Table 3
shows the arrangement of bytes, within each field type, when used by IBM PC
computers. All data sent to or from the OEM6 family of receivers, however, is read least
significant bit (LSB) first, opposite to what is shown in
Table 3
. Data is then stored in
the receiver LSB first. For example, in char type data, the LSB is bit 0 and the most
significant bit (MSB) is bit 7. Refer to the Section Channel Tracking Example in the
OEM6 Family Firmware Reference manual for a more detailed example.
