Upgrading the Gecko firmware

The process of upgrading the firmware in the Gecko could not be easier. The firmware
upgrade file is called Rasbora.bin and simply needs to be copied to the root level of your
Gecko's SD card. With the Gecko turned off, insert the SD card, then apply power. After a
few seconds you will see a message indicating that it is "Upgrading Firmware", which only
takes a few seconds. The Gecko will then restart and the new firmware features will be
available.
A Gecko will only upgrade its firmware if the Rasbora.bin file has a later firmware number,
otherwise the file will be ignored. After the upgrade the Rasbora.bin file remains in the root
folder of the SD card so that the card can be used to upgrade other Gecko recorders, but it
can be deleted from the folder at any time with no adverse effect on the Gecko.
Always check your settings after an upgrade to be sure something has not unexpectedly
changed, which can happen when upgrading from much older versions of firmware.
Ports & Wiring

Power connector

The two-pin connector is the power input to the Gecko, with the pin 1 as the supply voltage
or battery positive, and pin 2 as the ground or battery negative. If a wired power cable with
a matching plug has been supplied, it will have bare wire ends (red or white=positive;
black=negative) for connection to an external battery.
Gecko Compact 4ch uses LTW connectors (above, left) and other models use LEMO connectors (above, right)
On Gecko models that use LEMO connectors, the cable plugs simply push in when correctly
aligned (look for the red mark) and are locked in place. Pulling on the plug's body will slide
it back to unlock and remove the plug. On the Gecko Compact 4-ch, larger LTW connectors
with bayonet or screw locks are used.
