3. Quick start (Reader connected to PC via USB – Full R/W capability)
1. Connect the reader to the host via the USB cable, and switch the reader ON.
2. Windows will detect a new device. Install the “CP210x USB Composite Device”. This driver
can be downloaded from the manufacturer at Silicon Laboratories. Windows will detect
readers above serial number 5020016 as IPICO Proximity readers.
3. Data format: Refer to IPICO’s serial protocol document.
4. Quick start (Reader connected to Host via RS 422 - Full R/W capability)
1. Connect the reader to the host via the RS 422 cable, and switch the reader ON. The Host
can be a PC or any other field device like a PLC. If the host does not support RS422
interface, the user can use any commercial RS422/RS232 converter to connect reader to
the host.
2. Once connected the user can use HyperTerminal, Showtags or any other client application
that can communicate to the reader.
3. Data format: Refer to IPICO’s serial protocol document.
5. Quick start (Reader connected to Host via Wiegand™ - R/O capability)
1. Connect the reader to the host via the Wiegand cable, and switch the reader ON. Reader
will operate in Read Only mode.
2. The Wiegand settings will be hard coded during manufacturing as follows:
a. 26-Bit code. For a 24 bit ID, bits 16 to 39 of the IPICO Tag ID are used (least significant
24 bits excluding the CRC + 2 parity bits).
b. Tpw = 50us, Tpi = 1.8ms and a code retransmit rate of 100ms.
c. D0 and D1 are open-collector outputs. User need to supply external pull-up resistors
to VCC at the host device.
d. LED input can be driven by +5V signal from the host device.

3. Data format
The 26 bits of transmission from the reader to the panel consists of two parity bits and 24
code bits. The bits are transmitted in the order described. The first bit transmitted is the first
parity bit, P1, it is even parity calculated over the first 12 code bits. The last bit transmitted is
the second parity bit, P2, it is odd parity calculated over the last 12 code bits:
CODE FORMAT

P1: First, or even parity bit.
C: Code bits.
P2: Second, or odd parity bit.
E: Bits for calculation of even parity.
O: Bits for calculation of odd parity.
NOTE: Data format within the 24 code bits which include the partitioning of the bit, the
designation of the Most Significant Bit (MSB) or the Least Significant Bit (LSB) shall be subject
to definition by the panel and reader manufacturers and may remain proprietary.

6. Operations overview
The reader transmits CW carriers, which causes the tags in the RF beam to power up and start
backscattering their ID codes back to the reader. The RF unit receives the modulated backscatter
and decodes the tag ID’s. A time stamp is typically added by the reader for each tag read event
(Wiegand mode is 26-Bit ID only). The data from the reader is transmitted immediately
communication port to the host. No buffering takes place on the reader. When using the USB or RS
422 interface, additional data fields can be added. If more ID’s are received from the same tag
before its packet had been transmitted, a hit counter is increased. These hit counts are included in
the transmitted packet as “I” counts. The length of the tag ID data packet that is sent to the host
can be altered. The USB and RS422 readers can be used to WRITE USER DATA into EM4522 tags and
also setup these tags to operate in TTO mode. (TTO is a special operational mode of the tag in
which the tag will send its USER DATA pages in the presence of a RO or Non-modulating reader)
Refer to the instruction set in the serial protocol document or Showtags document – www.ipico.com.
7. Application notes
a. Read distances depends on the relationships between Tag size and Antenna
characteristics.
b. Electrical noise sources in close proximity to the reader may influence read performance. The
magnetic field produced by the unit may also cause slight interference with other sensitive
electronic equipment.
c. The USB interface allows the reader to be powered from the host as well as for bi-directional
communication between the host and the reader. An alternative isolated RS422 interface is
also available for integration into industrial point-to-point control applications. The reader is
typically used as a desktop registration reader, validation reader, printer programming head
or production line programming head, depending on how it integrates into the host
application.

8. Troubleshooting
Visual indicator guide
· GREEN Random flashing indicates valid tag ID’s are decoded.
· GREEN 1HZ flashing indicates Heartbeat (Shows Decoder is running).
· RED Steady indicates Power ON.
NOTE : in Wiegand mode the Greed LED will be under Host control
Table 1 Troubleshooting guide
9. Maintenance
This is a low maintenance device. The user must make sure that the reader is kept clean and dry
where possible. Do not use solvents to clean this unit. This unit will encase in a waterproof enclosure.
Do not use any switch mode power supplies unless approved by IPICO.
