：
ＣＬＳ
signal
：
Usually is high level. When magnetic cards with data swipe on the magnetic
head, CLS will output low level signal. After magnetic card swiping complete, it will restore
into high level. This signal is usually used to detect if there are magnetic cards swiping on the
magnetic head.
ＲＣＬ
signal
：
Usually is high level. When magnetic cards with data swipe on the magnetic
head, RCL will output impulse signal. After magnetic card swiping complete, it will restore
into high level. This signal is usually used to read data in the magnetic card. When RCL is
low level, data in RDT is effective. When programming, it usually read in negative edge.
Impulse width: 10us~60us.
ＲＤＴ
signal
：
Usually is high level. When magnetic cards with data swipe on the magnetic
head, RDT will output data signal of magnetic card. Please note that RDT signal level is
opposite to data. i.e., when RDT is high level, correlative data is 0; when RDT is low level,
correlative data is 1. Level feature is TTL (high level: >0.8* input voltage; Low level: <0.2*
input voltage).
Caution during operation
1 Cards should be inserted in the designated direction, and operation speed should be almost
same.
2 Cards using on the standard machine should comply with ISO7811.
3 Magnetic track of the card should not have foreign material, scratch or incompatible default
4 Cards should not put in the position close to magnetic iron to avoid degaussing card signal.
5 If you need to change the usage of products, please contact us or operate by technical
person.
6 If you swipe card too hard or have trouble in swiping card, please clean magnetic head (Use
cleaning cards).
