Introduction:
On the market sales of most of the access controller is mostly used in the Wiegand (Wiegand (WG) interface and a card reader connected, WG transmission to the nominal distance is 100 meters actually 20-60 meters in between, so we in the process of the implementation of the access control system often meet access controller and card reader device in long distance, this can cause the controller to receive the card reader information.
In order to solve this problem, we develop a Wiegand signal amplifier, the card WG output is converted to 485 signal, take advantage of 485 transmission, using twisted pair transmission line to the transmission distance of the WG signal greatly increased to 1200 meters maximum theoretical level. In addition to solve the problem of reliable signal transmission, but also has a very obvious cost advantage: converter. The price is reasonable. 2. Easy to install; 3. Transmission line without special requirements, ordinary super category 5 cable can easily reach 300 meters transmission distance with our scheme.
Matching WG to 485 converter with high anti interference MCU processing chip, built-in watchdog circuit, automatic detection equipment to do the state of the work, the work of automatic reset when the exception reset, to ensure that the converter will never crash. Converter appearance size: 70 x 41 x 23mm, the use of industrial connectors, to ensure convenient and reliable wiring, can be a long-term 7 x 24 stable work. Has been in the actual user site running 24 x 2 up to 7 years.
Amplifier can automatically identify the vast majority of the WG format, from WG26 to WG34 can be, including a variety of original WG card reader. Other applications that have special requirements, please provide information to assess the cost of custom, the cost of calculating the degree of ease of charge.
The installation and use of WG signal amplifier
The amplifier is composed of 2 WG converters, 2 WG converters are connected to the WG output / input of the reader and the controller, respectively. The converter's D0/D1 is connected with the reader / controller's D0/D1 one one. Power supply can be shared with reader / controller power supply. The converters are used to connect B-B A-A, as shown in figure:
Power supply:
WG converter using 9-15V power supply, the access controller can be directly used WG input port 12V power supply, static working current of about 20mA, also can be connected to the external 9-12v power supply adapter. Card reader terminal can share power supply with the card reader.
WG converter connection:
WG converter does not need to separate the transmitter and receiver to connect, any one can be based on the signal source for automatic identification and conversion, as long as the wiring can work correctly, greatly reducing the complexity of the construction. Transmission line in the 300 meters around the proposed general Super 5 types of network cable, one of the docking 485A/B, the other for the use of the visual reality in parallel as a power line. 300 meters above please refer to 485 information according to the actual situation in the field of wire selection and wiring planning.

Doing this way will save you 2.5-3.53% of netpay transaction charges and in case of out of stock will get full refund and dont need to wait around 2 week for NETPAY refund.
-No need to send us any email or sms after payment. Just remember to update your buynow order.
-For bulk order or quantity order can place order first and send us a pm to ask for best price.
SKIPPING NETPAY CHARGES (updated as of 20 JAN 2018)
Friendly reminder for those to avoid paying "NetPay" (2.5-3.5%) or preferably direct "Funds Transfer" (0%), please transfer your payment to one of our bank accounts above.
Once the transfer is done, kindly notify us by uploading the bank receipt to your order, we will then proceed your shipment once the payment has been verified.
NOTE:
a. Lelong charges extra 2.5-3.5% service fee of the total sales amount for every NetPay transaction, we recommend buyer to use Internet Banking (direct funds transfer), or Cash Deposit Machine to avoid charges.
b. PayPal charges up to 3.9% (local buyer) / up to 5% (oversea buyer) for service fees.
c. Payment clearance for cheque may take up 2 to 3 working days
d. Payment from third party bank may take up 1 to 2 working days
NetPay (via Credit card/Debit card)
-
It charges 3.5% service fee for every NetPay transaction
-
For example
Assuming, the total sales = Rm100,
NetPay service fee (3.5% + 6% GST) = Rm3.71,
Shipping fee Rm10 (+ 6% GST) = Rm10.60,
Total Price: Rm113.78
· P/S: If you pay using Credit Card via netpay, all out of stock item will not be fully refund because Netpay has charge 3.5%
example:
You have paid RM100. RM100 – 3.5% = RM96.50 will be refund only.
