5.4. rin-LINK 
The optional rin-LINK 
cable can be used to 
transfer setup and 
calibration information 
from a PC (eg. 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 rin-LINK cable to the PC using the DB9 connector.   
•  Attach the rin-LINK head to the left side of the instrument display 
using the permanent magnet located within the head of the rin-
LINK.   
WARNING:  The rin-LINK head contains a strong magnet and care 
should be taken with its proximity to electronic media (eg. credit 
cards, floppy disks, etc.) and/or other electronic instrumentation. 
 
5.4.1.  rin-LINK Activation  
A long press of the <GROSS/NET> key will toggle the rin-LINK 
infrared communications On/Off.   
When the rin-LINK has been (enabled) the following will occur: 
•  The instrument briefly displays the prompt rin-L. 
•  The editing annunciators (ie. GRP, ITM, etc.) will flash for up to five 
minutes while the instrument searches for activity.  During this 
period, the R320 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 
rin-LINK will be disabled and the editing annunciators will stop 
flashing.  The R320 will also revert back to the normal RS-232 
communications (ie. the SERIAL:TYPE setting will be re-activated).
