The Return Lever is used to return coins or clear jams . When pushed, the fly deck opens so that all objects within the Coin Validator are directed to the return cup . (See Figure 3 - 1 ) . Keypad The front of the Coin Validator is equipped with a five key touch - sensitive Keypad (See Figure 3 - 1 [ 4 ] ) which is used to dispense coins from an indi - vidual tube and to perform filling procedures to increase coin inventory before the unit is placed into operation (See Section 4 "Functions" and Sec - tion 7 "Operation" for further information) . Indicator Lights There are three Light - Emitting Diode (LED) indi - cator lights on the front of the Coin Validator posi - tioned beneath one another colored Green, Yellow, and Red, respectively (See Figure 3 - 1 [ 9 ] ) . These lights are mainly used for quick diagnostics, and current status indication (See Figure 3 - 1 ) . If the top Green LED lights or flashes, no faults are indicated and the device is working properly . If the middle Yellow LED flashes there is a definite gen - eral fault indicated that can usually be easily repaired . If the bottom Red LED flashes, a fault that must be remedied by a service technician is indicated (also see the Section 14 "Troubleshooting" appendix) . Interfaces There is a 40 - Pin Dual Inline connector on the back of the Coin Validator module (See Figure 3 - 2 [ 12 ]) . This module connects with the main chassis by means of a flat ribbon cable . On the top right front of the Coin Validator there is an 8 - pin RJ - 45 receptacle jack (See Figure 3 - 1 [ 2 ]) . It allows the Coin Changer to be connected to a Palm Pilot ® handheld device for configuration purposes . On the left side of the Coin Validator there is a direct 5 - Pin Printed Circuit Board (PCB) edge connector (See Figure 3 - 2 [ 11 ]) which previously allowed the Coin Validator to be connected to a program - ming PC or a JCM Test Station . DIP Switch Block Individual settings for inhibiting various coin types can be easily made by selecting the proper switches on the 10 - position DIP Switch Block located on the back of the Validator Module (See Figure 3 - 2 ( 13 ) as well as Section 7 "Operation" for detailed user information) .
