0566A03B-002/ EQT Medusa HID USB
REVISION 1.0, 2008-02-27
The Medusa 0566A03B-002 is a RFID Read-/Write-Device (short: reader) which is
compatible to all HID 125kHz prox cards. It provides an universal serial interface (USB) to
output or exchange data with a host computer (typically an Equitrac Page Counter Unit, a
printer or a copy machine) and a 125kHz inductive interface to supply power to and exchange
data with the HIDcompliant card (or other available form-factors such as tags, key-fobs). The
host computer can control a bi-colour LED and a beeper to interface with the user.
Mounting and Connection
The reader generates a magnetic field with the frequency of 125kHz which is influenced by
any electrically conductive material in close proximity to the device. When mounting the unit,
a distance to any such material of minimum 10 cm is required to ensure that there will be no
significant degradation of the performance in terms of read range and reliability. Mounting
the unit directly to metal would result in a severe reduction of read range down to zero
functionality. Care should be taken when testing the device after mounting at a problematic
environment: Read ranges and performance vary from card to card and very much from card
to tag or key-fob.
When mounting multiple readers, the distance between readers should be minimum 0.5 m in
order to avoid degradation of performance due to interference.
To connect the device to an Equitrac PageCounter, printer or copy machine, please make sure
the host system provides an USB socket intended for connection of the reader.
Operation
Whenever the device is connected to a proper power supply, it will switch on the internal
antenna and periodically scan for a card. Once a card has been detected, the card number is
read, the data converted and sent to the host system through the serial interface. To enable the
device to read cards, tags and key-fobs successfully, they should be placed centred above the
reader.

FCC:
Any changes or modifications not expressly approved by the party responsible for compliance could void the
user's authority to operate the equipment.
NOTE: This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant
to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful
interference in a residential installation. This equipment generates, uses and can radiate radio frequency energy
and, if not installed and used in accordance with the instructions, may cause harmful interference to radio
communications. However, there is no guarantee that interference will not occur in a particular installation. If this
equipment does cause harmful interference to radio or television reception, which can be determined by turning
the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following
measures:
-- Reorient or relocate the receiving antenna.
-- Increase the separation between the equipment and receiver.
-- Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.
-- Consult the dealer or an experienced radio/TV technician for help.
