9.11.1 Jumpers
Reader type is selected by the use of jumpers located in between the reader ports at W5 and
W11-W14. Refer to each diagram of reader-types on Section 5.0 [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 four jumpers at 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 leftmost jumpers at W5 in conjunction with the reader port jumper setting (see
Section 9.11.2 – next page).
