TinyGate - User's manual and assembly instructions
1. External
The power supply for the CAT/CI-V port comes from the RJ45 X2 socket.
This power is reduced inside the TinyGate with a linear voltage regu-
lator (D2, T3) to about 5.1V. The TinyGate board is pre-configured for
the external power supply of the CAT / CI-V Port.
2. Internal
The electrical supply to the CAT/CI-V port is internally taken from the
USB port of the TinyGate.
CAUTION! Due to a common ground it is not possible to have a
galvanic isolation between the TinyGate (the PC) and the CAT
port of the transceiver if you use the internal supply!
The CAT/CI-V port and the SQL (COR) input use a common
ground (defined with the SJ9 bridge), as a result, they should both be
powered from the same supply (internal or external)!
