FocusLynx Hand Control - Revision 4

Troubleshooting
Occasionally, the Hand Control screen may appear blank or locked in the “Waiting for Data” screen for
too long. If the screen is blank or the “Waiting for Data” message persists, first try simply unplugging
and re-plugging the coiled handset cable in the bottom of the hand control. If this does not solve the
issue try adding a ferrite core choke or contact Optec support. When changes are made in FocusLynx
Commander set up dialogs, the cable may need to be unplugged and then re-plugged to re-establish
communication between the hub firmware and FLHC firmware.
Contact Optec Technical Support (
) with any other issues concerning the
FocusLynx Hand Control option.
Upgrades
If the FocusLynx Hand Control firmware needs to be updated, a PIC chip replacement must be ordered.
Specify Optec #19695-FW to order a hand control firmware update. The firmware is provided in a 28-
pin DIP (dual in-line package) programmable integrated circuit
with the version number marked on the IC.
First unplug the coiled cable from the hand control. Remove the
FLHC back cover to expose the circuit board and IC socket. Note
the position of the notch indicating Pin 1. Gently pry the existing
firmware chip up and out of the socket and replace with the new
firmware PIC chip. Ensure that Pin 1 is in the same orientation as
the original. Re-attach the back cover and coiled cable. Connect
to the hub and watch for the firmware version number to appear.
Fine Focus Knob Upgrade
Owners of the first generation FocusLynx Hand Controllers may wish to upgrade to the second
generation which includes the Fine Focus Knob. This second generation upgrade requires returning the
hand control to Optec for addition of the rotary encoder and associated circuitry. Optec offers our
service item #17696 for the upgrade which includes the #19695-FW firmware update to the most
current version. Contact Optec for details and pricing.
