1. 41 Loading Firmware Loading new firmware to the Combolook is done using a Windows loader program called FDLDVB exe Also needed is the firmware hex file to load In the Combolook there are two different types of firmware used The main control firmware will have a name like CL HD 10 and the DVB module firmware has a name like SC DVB 1 3 bin Usually it will be necessary to only update the main control firmware Do not load any firmware without these types of name it will be for a different instrument and will not work on the Combolook Color HD Use the Version screen in the Setup Menu to determine the current software version In order to load firmware you must have a PC which supports an RS232 connection The firmware loading must be performed with the external charger connected The RS232 cable to be used is supplied as part of the kit with the Combolook Color HD Some laptops do not have an RS232 connection but a USB to RS232 adapter can be purchased at low cost Connect the Rs232 cable from the computer to the instrument Run the firmware download file FDLDVB exe Firmware Downloader Firmware Downloader Port About Exit Port About Exit Select Port Send Satlook Firmware Send DYB Firmware Select the RS232 port on the computer Normally the port is COM1 but some USB to RS232 will use some other port If desirable this USB to RS232 conversion device can be made to always
