A      TRIMBLE STANDARD INTERFACE PROTOCOL (TSIP)

1 6 8      Copernicus GPS Receiver

This packet requests Packet 0x8F-2B or marks it for automatic output. If only the first 
byte (packet sub-code 0x2B) is sent, an 0x8F-2B report containing the last available 
data will be sent immediately. If two bytes are sent, the packet is marked/unmarked 
for auto report according to the value of the second byte as shown in below.

To retain the auto-report setting for this packet, first set the setting accordingly and 
then save to non-volatile memory by issuing the packet 0x8E-26.
