Double Channel input Pulse type Coin acceptor and bill acceptor to PC interface

The WF-702USB is an pulse to interface module for most models of coin acceptor and bill acceptor products. The WF-702USB has a built-in USB port on its uplink communication port to interface with USB port on a PC and a downlink port with inhibit line to interface with pulse type validators.

( For MDB type Coin validator and bill acceptor to PC, please check:MDB-PC adapter)

1.0 Introduction
The WF-702USB is an RS232 interface module for most models of pulse type coin acceptor and bill acceptor products. The WF-702USB has a built-in USB port on its uplink communication port to interface with the USB port on a PC and a downlink port with inhibit line to interface with validators.
With the WF-702USB, the end operator can treat all different kinds of pulse type validators as a standard RS232 device and can concentrate on the real operation of the validator rather than the tedious interface work of the hardware discrepancy. On the PC platform, the software developer can easily program the validators via the WF-702USB with common computer languages such as Visual Basic / C++.

2.0 Compatibility
WF-702USB is a successor of the WF-700 model.WF-702USB is 100% functionality compatible to WF-700. With the DIP Switch, a more versatile configuration can be setup to interface with over 90% of the most commonly used banknote / coin validators found in the market.

3.0 Communications
This interface is a double three wire interface using a Transmit line (TXD), a receive line (RXD) and a Common line. The Host machine is thought of as being the Master device. The WF-700-RELAY / WF-702USB is the slave device that responds only to the polls (or requests) from the Master.
In this polled system, the Master requests information from the WF-702USB at a periodic rate. This rate can be as fast as every 30 milliseconds or as slow as the elapse time defined by the Lockout Timer. Faster rates are more desirable since overall system performance (in terms of bills/coins per minute accepted) will be higher at high poll rate system.
WF-702USB has a “Lockout” Timer feature that it will disable the acceptor if the specified poll rate is not met. In another words, if the host system is too busy to keep up with the desired minimum poll rate, WF-702USB will put the acceptor into the Disabled mode. The acceptor will be enabled again once the communication resumes.
