8. OSDP Operation
Rosslare O2S readers that support OSDP operation are compatible
with most OSDP commands. The reader address is set using DIP
switches on the back of the reader.
The DIP switch settings are as follows:
DIP Switch 1
This switch is used to select the reader output (Wiegand or OSDP):
Off = Wiegand
On = OSDP
DIP Switch 2
This switch is used to determine what cards are read:
Off = O2S cards and CSN of non-O2S cards
On = O2S only
DIP Switch 3
This switch is reserved for future use.
DIP Switches 4 to 8
These switches set the address of the reader for OSDP protocol.
DIP Switch 4 is MSB and DIP Switch 8 is LSB. The address is the DIP
switch state +1.
Examples:
All the DIP switches in Off position, state is = 0 => address = 1
All the DIP switches in On position, state is = 0x1F => address =
0x20 = 32
DIP switches 4, 6, 8 in On position and 5, 7 in Off position, state
is = 0x15 => address = 0x16 = 22
