Setting the Communications Mode
(CASI Mode)
In CASI mode, the reader splits the serial number into two parts for
Wiegand formatting. The other communication modes return the number
resulting from this split format. In this manner, all five output formats
yield the same number to the system. This number will not match the
serial number provided by the card manufacturer.
The following steps are for setting the communications mode in
CASI mode.
NOTE: RS-232 mode for Revision B printed circuit boards and higher.
1.
Remove power from the reader.
2.
Place a mini-jump over both pins of JP4; JP3 is open.
3.
Add power to the reader and listen for the number of beeps.
NOTE: The number of beeps indicate current communications mode
set.
•
1 beep = Supervised F/2F
•
2 beeps = Unsupervised F/2F
•
3 beeps = Strobe
•
4 beeps = Wiegand 4001
•
5 beeps = RS-232
4.
Push and release the tamper switch the number of times that
correspond to the communications mode desired.
NOTE: If you exceed the number of pushed listed below, an error
response will sound and flash. Simply repeat this step.
Modes:
•
1 push = Supervised F/2F
•
2 pushes = Unsupervised F/2F
•
3 pushes = Strobe
•
4 pushes = Wiegand 4001
•
5 pushes = RS-232
5.
Wait 5 seconds and then remove power from the reader.
