9.12.1 Jumpers
Reader type is selected by the use of jumpers located in between the reader ports at W4-W5 and
W7-W14. Refer to each diagram of reader-types in Section 5 [Reader Connections] for the proper
setting of these jumpers. Four other jumpers, located at W1, W2, W3, W6, and W15 designate
chip selection, and are set at the factory. They should not be changed unless directed by
technical support.
The setting of the jumpers at W4 and W5 (4W or 5W) determines how the jumpers next to each
reader port is set. Also, when using a 5-wire, 12VDC reader, you can control the voltage at PIN 1,
by moving the #3 jumpers at W4 and W5 in conjunction with the reader port jumper setting.
