GiS mbH TSHRW38 User Manual
TS-HRW38 Ethernet / USB HID / RS232
1. General:
The TS-HRW38 is a reader / programmer module with integrated antenna for communication
with contactless integrated circuit cards.
It is designed for using ISO15693, ISO 14443-3, Mifare Ultralight, Mifare Classic 1K and
Mifare Classic 4K Transponders, all operating at 13,56MHz.
Data transmission between the TS-HRW38 module and the host computer takes
place according the commands of
"GiS Programming Interface (SDK) for TS-HRW devices".

TS-HRW38 Ethernet / USB HID / RS232
2. Description:
The device is available in different variants. Depending on your needs it can be ordered as
automatic reading device (TS-HR38), as programmer device (TS-HW38) to modify contents
of transponders or as composite device (TS-HRW38) with both functions activated.
See also Section 6. Starting up for more information about the usage of the device and
controlling software.
2.1. Power Supply
The power supply depends on the interface used at the device.
If the USB Interface is used, power can be supplied by the 5V provided by the USB Bus.
If Ethernet or RS232 Interface is used, power is supplied by external 5V power supply.
2.2. Interface
The device uses a USB full speed interface 12MBit with hot plug support respectively a
Ethernet interface with 10/100 MBit or RS232 interface at 19200 Baud.
2.3. Contactless Transceiver
The MF RC632 handles the transceiver functionality for ISO15693 and ISO14443
communication at 13.56 MHz. Modulation is ASK with 0/100% (Type A).
2.4. Microcontroller
The microcontroller is a 8bit AT90USB1287. Is uses 128KB Flash, 8KB RAM and 4KB
E²Prom. It controls the MF RC632 via External memory interface and contains the USB
interface and the RS232 serial interface. When equipped with Ethernet interface, it controls
the XPort via serial interface. In order to avoid malfunction an external reset circuit is used.
2.5. Ethernet controller
The XPort embedded device server handles the Ethernet connectivity and communicates
through serial port with the AT90USB1287.
2.6. Oscillator
There are two oscillators on board. 8 MHz for AT90USB1287 and 13.56 MHz for
MF RC632. Frequency stability is both better than 100ppm.
