TinyGate - User's manual and assembly instructions
Introduction
The TinyGate Interface was created by Martin, IW3AUT and it’s a compact
USB interface for transceivers, which a ows operation in digita modes via PC
such as for examp e: PSK31, RTTY, WSPR, SSTV, EchoLink, APRS, Pactor, ROS as
we as many others.
As a 3-in-1 interface it makes available via a USB port a sound card interface, a
C T / CI-V interface and a PTT / SQL / CW / FSK with a galvanic isolation
between the transceiver and the PC with transformers and optocouplers. The
TinyGate Interface can be used with a wide variety of software applications for
digital modes, which are available as freeware, shareware or as commercial
products. As a resu t, this provides the amateur radio operator with easy and
manageab e access to the wor d of digita modes, thanks to the wide f exibi ity
of adaptation of this interface to a most any transceiver.

This assemb y box is made exc usive y for radioamateur and educationa -ex-
perimenta use. As a resu t, it shou d be assemb ed and used by an expert with
experience in the assemb y of e ectronic circuits.
We do not accept any responsibi ity for bodi y or materia damage caused by
the construction and use of this assemb y box. As a resu t, assemb e and use
this kit at your own risk.
The operation may not be guaranteed, and even ess so its e igibi ity for use of
certain app ications. The user shou d verify its app icabi ity for their own ap-
p ications and is responsib e for the atter.
Errors of access and use are factors that are beyond our contro , we are there-
fore not responsib e for bodi y or materia harm caused by these errors or in-
experience.
The guarantee app ies exc usive y to the individua parts (on the condition that
these are assemb ed correct y) and not to the assemb ed product. The afore-
mentioned RF-SYSTEM reserves the right to make modifications and/or im-
provements to the assemb y box at any time, without updating this manua .
The two kits, once assemb ed, may not be reso d if the necessary ega author-
isations have not been previous y requested and obtained.
Before using with a transceiver or receiver, the bridges on
the JP1 socket must be configured correct y.
Incorrect configuration of these bridges may cause damage
to the TinyGate and/or to the connected transceiver or re-
ceiver.
· It is advised that the parts are kept out of reach of chi dren and away from
pets, as they are a choking hazard.
· Do not inha e the fumes from the we ding. Use a fi ter or device to remove
these from the work station.
· Aerate the room after the we ding activity.

•3-in-1 USB interface, just only one USB cable to your PC: built-in USB
2.0 Hi h speed Hub
•Full galvanic isolation between radio and USB interface
•Integrated USB sound device:
The power supp y from the USB host is fi tered additiona y to keep a ow
noise on the A/D and D/A converters
Supported by the fo owing operating systems: Windows XP, Windows 7,
Windows 8, Windows 10, Macintosh OS X and LINUX.
Comp iant with USB Audio Device C ass Specification v1.0, there are no
custom device drivers necessary.
•Provides 2 independant integrated USB COM-Ports:
1) CAT/CI-V serial interface:
Support for fo owing radio contro ports: CI-V, FIF-232, IF-232
(RXD+TXD)
Supported by the fo owing operating systems: Windows XP, Windows 7,
Windows 8, Windows 10, Macintosh OS X and LINUX.
2) TT/SQL/CW/FSK interface:
Sque ch(COR) input, positive or negative ogic (for Echo ink and remote
contro app ications)
PTT re ay output: direct keying contro without VOX circuit
CW/FSK so id state output (can a so be used as PTT: The smart jumper
system a ow to use either a re ay or a so id state output as PTT)
Supported by the fo owing operating systems: Windows XP, Windows 7,
Windows 8, Windows 10, Macintosh OS X and LINUX.
•Contro s for receiver and transmitter audio eve
•Quick change USB and Radio interface connectors
•RJ45 connector for transceiver connection with a f exib e pin se ection
jumper socket (attached to MIC connector, accessory or data port works
with virtua y a transceiver). A detachab e radio cab e can be made eas-

patch cab e and cut/remove one of both RJ45 connectors), where you
can so der a suitab e connector for your transceiver. Here as examp e the
cab e for a ICOM IC7400 transceiver:
•Leds for USB Audio device, PTT and CAT RXD/TXD activity
•All communication software which support a standard sound card
and a serial port for the TT can work with the TinyGate. Due the in-
dependent sound interface and COM-Ports it can be used a so with any
combination of CAT, remote operation and data software ike MixW,
Hamradio De uxe, DigiPan, MixW, FLDigi, RemAud etc.
