Receiver Commands
BIT: Operational Diagnostic Tests
$PASHQ,BIT,[c1]
This commands queries for the results of the periodic operational diagnostic tests,
where c1 is the optional port designator for the output of the response. If a port is
not specified, the receiver sends the response to the current port.
The response message is output in the format:
$PASHR,BIT,c1,c2,c3,*cc
Table 6.6 outlines the response message parameters.
CLK: Clock Status
$PASHQ,CLK,[c1]
This command queries the real-time UTC clock status, where c1 is the optional port
designator for the output of the response. If a port is not specified, the receiver
sends the response to the current port.
The time in the CLK command is UTC.
The response message is output in the format:
$PASHR,CLK,d1,d2,d3,d4,d5,d6,d7,d8
