DR4205K SPECIAL OPERATING FEATURE
TheDR4205K reader hastwomodes of operation, dependentonthe setting ofaddressswitch SW1,
(whichsets theupper byteof theaddress): theNormal Mode(SW1 =0 or 8), and the PIN/Key Mode
(SW1 = 4, 5 or 6 or C, D or E). These two modes are described below.
NORMAL MODE
Address switch SW1 set to 0, the DR4205K operates in its normal mode. Address switch SW2
is then set to the physical S-Net address of the DR4205K: 1 through 9 and A through F (addresses
1 through 15). In order to address the 16th reader in the normal mode, SW1 = 8 and SW2 = 0.
Example: SW1 = 0 and SW2 = 1 to F sets normal mode for nodes #1-15;
SW1 = 8 and SW2 = 0 sets normal mode for node #16.
Operation in Normal Mode:
nDKR portion only enabled: the key is sent as a key, and no PIN is expected.
nVIP portion only enabled: the PIN is sent as a PIN, with the number of PIN digits to be
entered set in the SYSTEM command. No key is expected.
nBoth DKR and VIP portions enabled: the key is sent as a key, the PIN is sent as a PIN.
Both key and PIN are expected (in either order). The number of PIN digits to be entered
is set in the PIN DIGITS entry of the SYSTEM command.
PIN/KEY MODE
Address switch SW1 set to 4, 5 or 6, the DR4205K operates in its 'PIN/Key' mode, where: either
a) the PIN will be sent as a key, or b) the key will be sent as a PIN. The number of digits in the PIN
number is determined by the 4, 5 or 6 of switch SW1, and, again, address switch SW2 determines
the physical S-Net address of the DR4205K for nodes 1 to 15. In order to address the 16th reader
in the PIN/key mode, SW1 = C, D or E and SW2 = 0. NOTE: C = 8 + 4, D = 8 + 5 and E = 8 + 6.
Example: SW1-SW2 set as 41, 51 or 61, i.e. SW1 = 4, 5 or 6 and SW2 = 1 set node #1 in 'PIN/
Key' mode, for a 4-, 5- or 6-digit PIN, respectively; similarly for nodes 2 through 15; but
for node 16, for a 4-, 5- or 6-digit PIN, SW1-SW2 = C0, D0 or E0, respectively.
Operation in PIN/Key Mode:
nSW1 set to 4, 5, or 6 (or C, D or E): determines the number of PIN digits, 4, 5 or 6, (which
must match the number of digits set in the PIN DIGITS entry of the SYSTEM command)..
nDKR portion only enabled: the key is sent as a PIN.
nVIP portion only enabled: the PIN is sent as a key.
nBoth DKR and VIP portions enabled: the key is sent as a key, the PIN is sent as a PIN.
Both key and PIN are expected (in either order). The number of PIN digits to be entered
is set both in SW1 and in the PIN DIGITS entry of the SYSTEM command. (Note that with
both the DKR and VIP portions enabled the operation is the same as for the normal mode.)
