RACS Format
When using RACS format, the PRTxxLT reader
communicates with the access controller via CLK/DTA
lines. Unlike in the Wiegand
and Magstripe formats, the
PRTxxLT unit using RACS format requires an individual
address (ID=0…3) to be set during configuration of
reader’s operating mode (Memory Reset procedure). In
RACS format, communications between the PRTxxLT
reader and the host is bidirectional which allows the
controller to monitor the communication. The reader’s
LED-s and the buzzer are controlled by the host unit.
When all LED-s are flashing it indicates that reader lost
communication with the host unit.
When in
RACS mode triggering of the IN1 disables
reading of the card and keypad. This input can be used
for temporary disabling of the reader. The IN2 is not used
in
RACS mode. PIN is transmitted as a whole when # key
is pressed.

ESET
The Memory Reset is a procedure which erases reader’s memory and restores factory default
settings. It also enables programming of operating mode and additionally it enables configuration
of IN1 and IN2 inputs in Wiegand and Magstripe Terminal modes.
Memory Reset procedure(variant 1 for RACS format):
1. Power down the unit.
2. Remove all connections from CLK and IN1 lines.
3. Make electrical bridge between CLK and IN1.
4. Restore power.
5. While LED OPEN (green) is flashing and is accompanied with continuous sound
disconnect CLK from IN1.
6. Wait till LED SYSTEM starts flashing.
7. Enter three digits which will configure the reader for required operating mode i.e.
[000].. [003]. Reader generates two beeps with every entered digit.
8. Once the previous step is completed reader automatically ends the Memory Reset and
switches to normal operation.
Note: When in step 7 an unknown operating mode is entered or no operating mode is entered for
20 s then reader will automatically exit the Memory Reset procedure.
Memory Reset procedure(variant 2 for Wiegand and Magstripe formats):
1. Power down the unit.
2. Remove all connections from CLK and IN1 lines.
3. Make electrical bridge between CLK and IN1.
4. Restore power.
5. While LED OPEN (green) is flashing and is accompanied with continuous sound
disconnect CLK from IN1.
6. Wait till LED SYSTEM starts flashing.
7. Enter three digits which will configure the reader for required operating mode i.e.
[020], [021] or [1xx]. Reader generates two beeps with every entered digit.
8. When LED SYSTEM is on, enter two digits to define the function of IN1 input:
[11]: Line off
[25]: LED STATUS control
[28]: Buzzer control
[29]: LED OPEN control
