Appendix Q - 635 DPI Installation
[STEP 4] 635-DPI PREP: READER VOLTAGE
CAUTION!
Do NOT connect a 5V Reader directly to a 635-DPI board.
Install the voltage regulator before
connection 5V readers to a 635 board.
[STEP 5] 635-DPI PREP: DOOR SUPERVISION (resistors & settings)
NOTES:
If you are
not
using door contact supervision, you can skip this step
Enable door contact supervision in the System Galaxy
Reader Properties screen
. You
must choose the setting you are actually using (i.e. series, parallel, or series-parallel).
1. Install EOL resistors as follows:
The factory default value on the board is 4.7k ohms. You can keep this or change it
if you desire since the supervision resistor is mounted in a resistor socket.
The EOL resistor(s) must be the same value as the on-board socketed resistor.
The EOL resistors must be physically installed at the device. You may install the
resistor(s) in series, parallel, or series-parallel configuration.
