4.2 - Wiring the user inputs for use as counters
GS120 user inputs can be congured to run in counter mode. To enable the counter
mode options, User input 1 must rst be set to Counter (see 6.4B). User input 1 is
always used as the count pulse input. Counter inputs are wired as shown below:

User input 2
User input 3

Sensor 1
Sensor 2
Sensor 3
Multiple sensors may be connected, and any combination of NPN, TTL and switch
contacts may be used for sensors 1, 2 or 3.

In counter mode, additional options become available:
›Slow debounced counter mode and Restore count at power on may be acti-
vated or deactivated (see 6.4C-D).
›Additional input functions will become available on user inputs 2 & 3: Count
direction, Gated count, and Reset count (see 6.4E-F and Appendix C).
Note that when using counter mode, it is advisable to set both the Com 1 and Com 2
inputs to Disabled (see 6.2D). If Com 1 and/or Com 2 are still active, then the count
value will be summed with the values obtained via the serial ports.

that are driven from a solid state output. Use the and buttons to select
either Yes or No, and then press .
Relays or mechanical switches will oen exhibit contact 'bounce' when the contacts open or
close, which may cause false count pulses to be registered. In debounced counter mode, the
GS120 will only accept an input pulse as valid if it remains active for 20ms or more. This limits
the maximum frequency to 25Hz.
D _ _ Restore count at power on scrolls across the bottom row, and the current
setting appears in the top row. Use the and buttons to select either Yes

AAPPENDIX A - SUMMING
Summing is enabled when both Com 1 and Com 2 serial inputs are congured to
receive serial strings. In this mode, the value shown on the display is the sum of the
input values from Com 1 and Com 2.
Although the counter mode is not intended to be used in conjunction with the serial
inputs, if it is, the value of the counter will also be summed with the value of the
serial input(s).
Disabling Com 2 and the counter will automatically disable Summing mode.
Appedix A notes
A In Summing mode the decimal point and units information will be taken from
the Com 1 string (if the display options are set to use decimal point and/or
units information from the incoming strings). Care should be taken in Summing
mode to ensure that both weighing instruments are outputting the same meas-
urement scale.

BAPPENDIX 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 de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 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 rst character in the string is not constant. If
the start character is speci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 specied, if they
are constant values, or set to Ignore if they are not xed.
The GS120 will check that all three leading characters match their values (if
speci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
