Page 13 This parameter relates to the output rate of the device driving the GS120. If the GS120 has not received an output string from the external device within the specifi ed time, it will treat this as an error and the display will change to show that it has lost communications.
Page 14: Display Setup
If you select a unit, a single character unit (K, t or L) will be displayed in the right-hand digit of the GS120. This feature does not perform any conversion calculations. _ _ Brightness scrolls across the bottom row, and the current display brightness appears in the top row.

Counter functions (including Gate Count, Count Direction and Reset Count) are only available if Counter is selected as your User 1 input function in 6.4B (see 4.2 for...
Page 16 Relays or mechanical switches will oft 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.
Page 17 If you selected Yes, connect a mA or volt meter across the analogue out- put connector (see section 4), and then continue to 6.5E.  If you selected No, skip to 6.5G now. Copyright © 2014 Gedge Systems GS120-MAN-14V05 (0307)

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. Copyright © 2014 Gedge Systems GS120-MAN-14V05 (0307)
Page 20 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.
Page 21 In this case, the 3rd to last, 2nd to last and/or end character may be specifi ed. Any/all of these characters may be set to Ignore if they are not fi xed. The GS120 will check that all three end characters match their values (if speci- fi ed), before the string is accepted.
Page 22 The GS120 will then treat this as the fi rst (or last) character, and ignore any un- wanted characters before (or aft er) it. As long as the distance between this char- acter and the weight string remains constant, the string will still be accepted.
Page 23 GS120 user inputs can be confi gured as Start/Stop controls for the traffi c light seg- ment, or as counter controls (if the GS120 is confi gured to run in counter mode). To enable counter mode options, User input 1 must fi rst be set to Counter in 6.4B (see 4.2 for more information on counter mode).
Page 24 Both Com 1 and Com 2 must be set to Disabled in 6.2D. The Com 2 port can then be used to connect the GS120 to your PC or PLC device. Com 2 will revert to a simple ASCII mode operating at 115,200 baud, 8 data bits, no parity, 1 stop bit.
Page 25 Text strings cannot be greater than 100 characters in length. The GS120 has a 7 segment display designed for numeric digits. Because of this, some alphabet and special characters are diffi cult to display, and a combination of upper and lower case letters are used.
