Serial or Telnet I/O Functions

4.1 Overview and Format

Shortly after power-up, the utility port will be ready to receive commands. To ensure the

unit receives data input accurately, wait until the message Searching for

Satellites...

has been on the front panel before entering any serial or Telnet

commands.

You can send data to, or request data from, the unit by sending serial or Telnet commands

using ASCII character strings. The general form of these commands is:

F<FUNC#><Enter>

where:

F = ASCII character F

<FUNC#> = two-digit function number

<Enter> = input line terminator

More specifically, the data input and output formats are:

F<FUNC#>[<SP><FIELD>]<Enter> (input)

F<FUNC#>[<SP><FIELD>]<CR><LF>

(output)

where:

F = ASCII character F

<FUNC#> = function number

<SP> = space

<FIELD> = data entry or request

<CR><LF> = output line terminator

[ ] = encloses a phrase that is repeated as often as

necessary

Output strings are kept to fixed lengths whenever possible. This means that numeric

values often contain many leading blanks. This user’s guide represents output strings in a

fixed font. For example:

F60 prn 14 good enabled sig level= +21.37<CR><LF>

1 2 ... 58 59 60 61 62 63 64 65 66 67 68 ... 147 148
