Serial Interface

[b54so]

I know on the other thread (Thread: New GEOSATpro microHD Receiver) it was mentioned that the internal serial port header is used for emergency recoveries. Does the serial port also support remote commands such as channel up/down, menu, channel number, ect.? If so, will there be a command list available? I’m hoping I can get rid of the IR emitter running out of the xbmc box I have for a more reliable serial connection.

BTW – I’m pumped to get my hands on one of these little guys and finally dump my dying S10!!!

Thanks!

The serial port is a 4 pin header connector on the PCB. I have never explored the unit to determine if serial commands could control basic remote control functions. I have the impression that navigation and control is not possible via the serial port.

Serial port maybe used in the event that the USB is disabled by firmware error or for old school upload/download of firmware, user data and backgrounds. Serial logging programs can also display STB function routines.

Is this a standard cable I can buy easy somewhere if not, will the manual have a schematic showing which pins are tx,rx and gnd so I can make my own. I hope I never have to use it, but I like to be prepared just in case.

Thanks Brian!!

Here is the diagram for the 4 pin header on the PCB.

Thanks, Brian. I need to find a place I can put this so it is not lost.

You need to be careful about these serial setups that have 5VDC on them as they're typically not compatible with standard RS232-C.

They sell "USB TTL" adapters for cheap (<$2) on eBay.

Are the signals RS232 levels (+/- 12V) or TTL levels ( 0/5V) and require a TTL to RS232 level converter like the MAX232 line of ic's?

Thanks Brian.

HEADER == not connector. I am a newcomer to this kind of thing -- only since 1964. Header has always meant expect TTL or in rare cases a standard voltage level so check. RS232 means a connector --

RS232 means a connector --

RS-232 describes voltages. The voltages are +/- where TTL is high and low.

It has been implemented over any number of different connectors from DB to DIN and RJ12.
