Use of the RS232 interface
The serial R232 interface of the receiver offers the facility for the connection of a PC.
Contact SmartSat for software tools to use this interface from any compatible PC
running a version of Microsoft windows.
Software is available for uploading / downloading and edition your channel list, for
remote control of the decoder by PC instead of infrared commander and for firmware
upgrades.
Do not use any prepared firmware upgrades other than those from SmartSat.
The use of prepared software updates which are not from us can damage your
Oyster Digital and will void warranty.
For the connection of the receiver to a PC you require a serial cable with 1:1 Pin
arrangement. That is all pins will be directly connected. On the PC side the cable has a 9
or 25 pole D-SUB socket, intended for the serial connection of your PC. A 9 pole D-
SUB plug is required on the receiver side. A “mouse extension cable” is supplied in this
form and can be used.
The receiver socket is occupied as follows:
1, 4, 6 – 9 Not occupied
2 TXD
3 RXD
5 GND
