1 What is TWN4?
1 What is TWN4?
TWN4 is the name of a powerful and versatile series of RFID readers and writers. Here are
some of the outstanding features:
• Operation in two frequencies bands: 13.56 MHz (HF) and 125 kHz / 134.2 kHz (LF)
• Modular concept consisting of core modules, carrier boards, antennas and complete
devices in housing.
• Security features such as slots for secure access modules or cryptogrphic functions.
• Possibility to write programs which are running on TWN4 itself (Apps).
• Standalone or host-based operation.

The core module contains voltage regulator, control unit, RFID front ends and communication interfaces.
2.1.1 Dimensions
The dimensions of TWN4 Core Module are as follows.:
2.1.2 Connectors
The TWN4 Core Module has several connectors on-board. There are three connectors (A, B
and C) which connect either to a carrier board or to a host. Furthermore, there is a antenna
connector and a optional position for placing a coaxial connector.

The connectors A, B and C have identical pitch. Following type of connector is recommended:
• Dual row header
• Pitch 2.0mm
• Pin shape square
• Pin width 0.5mm x 0.5mm
• Length of pins appropriate to custom requirements
2.1.2.1 Connector A
The connector A is intended for connecting a cable to the TWN4 core module, which allows
communication with a host. Typically, such a cable is either type USB or RS232. Various
appropriate USB and RS232 cables are available from stock.
There is a right-angle connector mounted on-board, which is type Hirose, DF11 series.

A2 USB_D+ USB Data +
A3 UVCC USB VCC
A4 USB_D- USB Data -
A5 V24_RXD RS232 RXD (Input)
A6 GND Ground
A7 V24_TXD RS232 TXD (Output)
A8 MGND Cable Sense
Note:
If pin A6 and A8 are connected to each other this has two effects:
1. The firmware of TWN4 changes host channel to RS232
2. The integrated circuit, which is interfacing to voltage levels of RS232 is powered up.
Following order codes for connector A and mating parts:
• Pin header on TWN4 Core Module: Hirose DF11-8DP-2DS(24)
• Mating part (crimping socket): Hirose DF11-8DS-2C
• Mating part (crimping contact): Hirose DF11-22SC (22 AWG)

series resistance of the antenna should be lower than 10 ohms.
2.1.2.4 Connector HF1
HF connector 1 is a UMCC series 50-ohms output, which is connected internally in parallel
to pins C1 and C2.
2.1.2.5 Connector HF2
Position of HF2 offers the possibility to place another 50-ohm connector. It is connected
internally in parallel to pins C1 and C2. There are several series of RF connectors, which
can be used for position HF2, like SMA, SMB, SMC, MCX.

2.1.3 Jumpers
There are several jumpers on-board of the TWN4 Core Module. Depending on the requirements these jumpers can be soldered together.
Jumper Function
J1 The function is identical to pins A6 and A8. If J1 is closed,
the RS232 interface is turned on and the host channel is
assumed to be RS232.
J2 Same function like J1 but other side of PCB.
J3 This jumper must be closed, if TWN4 Core Module is pow-
ered via connector A, e.g. from USB. It connects VCC from
the Core Module to the on-board voltage regulator, which is
supplied from connector A. If TWN4 Core Module is mounted
on a carrier board, this connection can be avoided by connecting pins B3 and B4 at the carrier board, which results in
exactly the same functionality.
J4 This jumper is for internal purposes only.
2.1.4 Power Supply
The picture below is showing, how power is routed through TWN4 Core Module:
