I. Brief Introduction
SU90 serial products are hand swipe operated magnetic card reading machine with RS232
interface, adopting high integrated magnetic card decoding chip. They have small electricity
consumption and strong interference resistance. They comply with ISO-7811、7812 magnetic card
decoding standard completely. It can read card bi-directionally, free to choose data with or without
enter key and has intelligent lights to alert if card data is read correctly. Exquisite magnetic
installation structure makes card reading more stable and reliable, which is our patented
technology. Reasonable product design makes products small and compact.
II. Technical Feature
Bi-direction card reading, high capacity program design, high card reading ability. Can
free to choose enter key between data of each track. Can customize tract starting character.
3-Dimensional magnetic head design makes magnetic head contact well with cards, and
ensures cards to have least abrasion.
Adopting arm suspension type magnetic head assembly method enables machine with
soft elasticity and good hand feel. Elasticity will not change in 10,000,000 times, which
greatly increases life span of magnetic head.
Installing magnetic head in the magnetic head box makes track position of magnetic

head more precise to ensure success card reading rate, and appearance of product looks more
beautiful.
Specific integrated circuits guarantee AMP 15% of the card can work properly.
Dual-track static current of the whole machine is below 4mA/5V.Strong interference
resistance.
Precise electric circuit disposition can read high magnetic card at 4000Oe completely.
Magnetic head adopts platinum manganese alloy material, which makes it life span over
800,000 times

VII Wire Connection and Operation
Wire connection refers to the below details information:.
1)Power connector, set the interface to the PC's keyboard interface (power DC5V)
2)Indicator: card swiping succeeds
Light display data is being uploaded (If data is in uploading process, you must wait for data
transfer is completed and then swipe card)
3)Data transfer interface, this interface to connect a PC's serial port (data upload)
Power interface and data transfer port, after the connection is completed, install the company's
Rxx installer (080 426).If the installation is successful, please select the serial interface, enter the
interface and open the serial port for testing. (Or use other serial port with serial assistant software
testing)

Lights indication:
1. When power connects well, indication light will show green.
2. When card swiping succeeds, indication light will blink one time.
When card swiping fails, indication light will blink continuously three times.
VIII Caution during operation
8.1 Cards should be inserted in the designated direction, and the speed of card inserting
should be almost same.
8.2 Cards using on the standard machine should comply with ISO7811.
8.3 Magnetic track on the card should not have foreign material, scratch or
incompatible default
8.4 Cards should not put in the position close to magnetic iron to avoid degaussing to card
signal.
8.5 If you need to change the usage of products, please contact us or operate by
technical person.
8.6 If you swipe card too hard or have trouble in swiping card, please clean magnetic head
(Use cleaning cards).
