5.4 GSE-LINK
The optional GSE-LINK cable can be used to transfer setup and
calibration information from a PC (e.g. to be stored for later use and/or
transferred to other instruments). It can also be used to download software
upgrades to the instrument from a PC.
• Attach the GSE-LINK cable to the PC using the DB9 connector.
• Attach the GSE-LINK head to the left side of the instrument display using
the permanent magnet located within the head of the GSE-LINK.
WARNING: The GSE-LINK head contains a strong magnet and care should be taken with its proximity to
electronic media (e.g. credit cards, floppy disks, etc.) and/or other electronic instrumentation.
5.4.1 GSE-LINK Activation
A long press of the <GROSS/NET> key will toggle the GSE-LINK infrared communications On/Off.
When the GSE-LINK has been enabled the following will occur:
•
The instrument briefly displays the prompt rin-L.
•
The editing annunciators (i.e. GRP, ITM, etc.) will flash for up to five minutes while the instrument searches for
activity. During this period, the instrument also disables the RS-232 communications.
•
Activity Located: If the instrument is successful in locating activity, the editing annunciators will continue to
flash during the entire period of communications.
•
No Activity Located: If the instrument fails to locate activity, the GSE-LINK will be disabled and the editing
annunciators will stop flashing. The instrument will also revert back to the normal RS-232 communications (i.e.
the SERIAL:TYPE setting will be re-activated).
6.0 CONNECTIONS
6.1 Cable Connections
•
All cable connections are made to the rear of the instrument using screwless terminals.
•
Wires must be stripped of insulation by at least 10mm.
•
To install, depress the orange lever beside the terminal required and push wire into the hole. Release the lever
and pull gently on the wire to ensure it is securely trapped in the terminal.
6.2 DC Power (DC PWR +, DC PWR –)
•
The DC supply need not be regulated, provided that it is free of excessive electrical noise and sudden
transients.
•
The instrument can be operated from a high quality AC wall transformer as long as there is sufficient capacity
to drive both it and the load cells.
