All letters sent with the serial transmission will be ignored except for those
used to separate the individual values.

Note:

For date and time, Isis uses the NMEA0183 standard. See ‘How

Isis Works with NMEA0183 Strings’ in Volume 2

As soon as you put Isis in Record mode, Isis will begin monitoring the serial
ports for transmissions. To test the interface, use the COM Port Test option
in the Tools menu (see ‘Com Port Test’, Isis User’s Manual, Volume 1) or
choose Test in the Serial Port Setup dialog box. Both access methods lead
to the same com Port Test dialog box.

Template entries are CASE SENSITIVE (that is, upper or lower
case entries are treated as unique entries) and must not contain
any space characters. Values are decoded as METERS except
where noted. For Isis to interpret northings and eastings as feet,
the template entries must include an upper case F.

D.3.2

Values Allowed Over Serial Interfaces and

Stored by Isis

Isis has a wide range of user-defined tokens that you can use in your
templates. When some of the user-defined tokens are surrounded by
delimiters, the meaning of the token changes. Isis can use and store many
character tokens over a serial interface (Table D-2).
Note:

In Table D-2, some tokens are enclosed in delimiters. Delimited

tokens are distinct from non-delimited tokens. In the table, we have used
braces as delimiters, but we could have used parentheses or brackets — all
are valid; Isis treats them the same. Both types of tokens (delimited and
non-delimited) are explained in the table.

value.)
