General Information
In addition, your DG16 could have one or more of the following hardware options:
• A optional third RS-232 serial port
• TTL connections for Ports A and B and optional Port C instead of RS-232
connections
• A OSX RF connector instead of a right angle SMA connector for the RF
connector
• 3.3 VDC as the prime power instead of 5 VDC
Receiver Options
The DG16 has a number of available options. The options that are set in the
receiver will determine which commands and features you can use. For example,
if the photogrammetry option is not installed, you will not be able to use the
$PASHS,TTT command to output event time tags from the serial port.
The $PASHQ,RIO command queries for the receiver’s configuration. The
response message includes version numbers for the processor and channel
firmware, a list of installed options, and the receiver’s serial identification number.
The response is output in the format:
$PASHR,RIO,f1,f2,f3,f4,f5*cc
where Table 1.6 outlines the parameters.
The DG16 has 18 available options. Each option is represented by a letter or
number presented in a certain order. The presence of given option is indicated by
the associated letter or number. If the letter or number is displayed, the option is
installed. A dash (“-”) indicates that the option is available, but not installed. An
underscore (“_”) indicates a reserved option slot.
