D.3.59 RXSTATUS Receiver Status
This log conveys various status parameters of the SPAN-SE receiver system. These include the
SPAN-SE Receiver Status and Error words which contain several flags specifying status and error
conditions. Receiver errors are handled differently based on where the error occurs. If an error occurs
on the SPAN system (shown in the Receiver Error word) the receiver will continue to operate as best
as possible. If an error occurs on either the internal OEMV-3 or OEMV-2 card (shown by the Error
Flag field in the corresponding status word), that card will idle all channels, turn off its antenna, and
disable the RF hardware, as these conditions are considered to be fatal errors. Shut down of either the
OEMV-3 or OEMV-2 in this way will result in some loss of functionality for the SPAN-SE.
The receiver gives the user the ability to determine the importance of the status bits. In the case of the
Receiver Status, setting a bit in the priority mask causes the condition to trigger an error. This causes
the receiver to idle all channels, turn off the antenna, and disable the RF hardware, the same as if a bit
in the Receiver Error word is set.
Receiver errors automatically generate event messages. These event messages are output in
RXSTATUSEVENT logs. It is also possible to have status conditions trigger event messages to be
generated by the receiver. This is done by setting/clearing the appropriate bits in the event set/clear
masks. The set mask tells the receiver to generate an event message when the bit becomes set.
Likewise, the clear mask causes messages to be generated when a bit is cleared.
If you wish to disable all these messages without changing the bits, simply UNLOG the
RXSTATUSEVENT logs on the appropriate ports. See also the UNLOG command on page 204.

1. Field #4, the receiver status word as represented in Table 76, is also in Field #8 of
the header. See the ASCII Example below and Table 76 on page 334 for
clarification.
2. Many OEMV status bits have been redefined to match SPAN receiver hardware.
Some bits (such as model, temperature, position solution) are mapped directly from
the OEMV-3.
When logging RXSTATUS, the SPAN-SE receiver data is displayed first (error bits
then status bits) then the OEMV-3 status bits then the OEMV-2 status bits.
In the event of a SPAN-SE receiver error, the LEDs flash the binary number of the
receiver error. Red is “1” and green is “0”. If you have an invalid auth code, the
LEDs will be green-green-red-green-red, which is 5 in binary and that means bit 5
of the receiver error word is set.

and Operation User Manual.
