TinyGate - User's manual and assembly instructions
PWR Given the galvanic isolation of the interface CAT/CI-V it is necessary
to supply it with external power (8-15VDC / 20mA). This power
may for example be taken directly by some transceivers from the
microphone connector, the DATA or ACCessory socket. In the case
the CAT/CI-V interface of TinyGate is not used or in cases where
galvanic isolation is not required, it is not necessary to get any
power supply from the transceiver.
COR/
SQL
Input - Squelch
Certain applications, (e.g. Echolink) support and use for the carrier de-
tection and/or channel busy detection by this signal from the trans-
ceiver, but only some transceivers have this output available on a con-
nector. On several transceivers of this sort it is necessary to get the
SQUELCH signal from inside. The SJ6 and SJ13 bridges define
whether this signal should be interpreted with a positive or negative lo-
gic.
CW/
FSK
Output - CW or else FSK (max. 50VDC / 50mA)
It is a transistor output from a optocoupler. If necessary, you may
connect this output with a 1.5kOhm-resistor to +5V (Pull-Up)
through the SJ11 solder bridge.
GND Ground (GND), connected to the shield of the RJ45 X2 socket
and the RJ45 cable towards the transceiver. This ground is
separated from the USB-ground of the circuit on the board and
should be connected to the ground of the transceiver via the RJ45
patch cable or the CW / FSK cable.
GND Ground (GND), connected to the shielding of the RJ45 X2
socket and the RJ45 cable towards the transceiver. This ground
is separated from the USB-ground of the circuit on the board and
should be connected to the ground of the transceiver via the RJ45
patch cable or the CW / FSK cable.
The RJ45 socket X2 is exclusively provided for the con-
nection of a transceiver and not an Ethernet network
port. Hence, a network device, such as a DSL router or
similar device for example, must not be connected, other-
wise it may be damaged by the TinyGate and/or the con-
nected network device!
