APPENDIX B - LAST RESORT
The last resort option can be used when trying to connect the GS120 with an instru-
ment which is not included in the device type list, or one which is using a custom
output string.
It allows the user to defi ne key characters in the output string, which enables the
GS120 to accurately extract the weight value from the string.
Start of string character / 2nd character / 3rd character
Many output strings contain a fi xed start character at the beginning of the
string. You may choose to either specify this start character, or select
Ignore
from the character options if the fi rst character in the string is not constant. If
the start character is specifi ed, the GS120 will wait until it receives this character,
and treat this as the start of the string.
The second and/or third characters in the string may also be specifi ed, if they
are constant values, or set to
Ignore
if they are not fi xed.
The GS120 will check that all three leading characters match their values (if
specifi ed), before the string is accepted.
Count from 1st character to start of weight string
This option is usually used in conjunction with the 1st, 2nd, or 3rd characters
from the start of the string. Once the start of the string has been detected, the
user can specify where the weight information is in the string, by counting the
number of characters from the 1st character to the start of the weight string. If
this option is not applicable, select
Ignore
from the count options.
Length of weight string
This is used to specify the length of the weight string in characters, and should
never be set to
Ignore
.
