3.10.  opto-LINK (Optional)  
A temporary infrared communications link can be established between the instrument and a 
PC using an optional opto-LINK cable. The optional opto-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.  
The PC end of the opto-LINK cable is a standard female DB9 connector, or USB connector. 
The instrument end of the cable consists of an infrared transceiver, which attaches to the left 
side of the instrument display. To facilitate a quick and simple connection, the infrared 
transceiver is secured in place by a permanent magnet located within the head of the opto-
LINK.  
Refer to opto-LINK Activation page 23 for more information. 
WARNING 
The opto-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.
