There are two transistor outputs (IO1 and IO2) available in the controller. The lines are of the open
collector type, i.e. in the normal (off) state represent high impedance and in the triggering state
(the output is on) they short to supply minus. The IO1/IO2 lines can switch current up to max 1A
DC while voltage connected to the output must not exceed 15V DC. In case of over-current state,
the IO1/IO2 lines are automatically switched off and the controller automatically restarts.
Note: If you observe that triggering IO1/IO2 output makes device to restart it might suggest that
current switched by the output exceeds its maximum allowed level.
RS485 Communication Bus
The RS485 bus consists of two signal lines A and B. In the RACS 4 any communication bus topology
can be used (star, tree or any combination of the two), in other words RACS 4 accepts free bus
topology. The matching resistors (terminators) connected at the ends of transmitting lines are also
not required. In majority of cases communication works without any problems using any cable type
(ordinary telephone cable, shielded or unshielded twisted pair etc. e) but the recommended one is
an unshielded computer twisted pair one. Using shielded cables should be limited to installations
liable to strong electromagnetic interferences. RS485 communication standard used in the RACS 4
guarantees a proper communication in a distance up to 1200 meters and features a high resistance
to interferences. For communication on longer distances, the UT-3 or UT-4 interface should be used.
A pair of UT-3 interfaces increases communication distance by additional 1200 m, and using an UT-4
interface makes possible to utilize communication through a computer network (LAN or WAN).
Connecting Readers and Extension Modules
The controller can cooperate with one additional reader of PRT series configured to RACS mode with
ID0 address. It can also cooperate with XM-2 I/O extension module. Both an additional reader and
an extension module can be connected to the controller using the same CLK and DTA lines. For CLK
and DTA lines any type of cables can be used as well. The guaranteed communication distance is
150 meters. Each device connected to CLK/DTA lines must have its individual address from 0–15
range. This address should be set up before particular device is connected to the controller.
Note: Devices communicating using the RACS Clock & Data standard (e.g. PRT readers) can be
connected to the controller with cables significantly longer than 150m (even up to 500m), but the
communication in such conditions is not guaranteed by the vendor.
Memory Reset
The Memory Reset procedure clears all existing controller settings, restores factory ones, and
enables for enrolment of the new MASTER card/PIN and new ID number (address) of the controller.
After
Memory Reset , the controller automatically switches to normal working mode.
Simplified Memory Reset Procedure (version 1)
This method clears entire memory and allows for programming of a MASTER card however doesn’t
allow for programming of the controller’s address (address is set to ID=00). This procedure doesn’t
require use of a keypad.
• Remove all connections from CLK and DTA lines
• Short CLK and DTA lines
• Restart device (switch power supply off and then on or short RST contacts for a while) – all
the LED indicators on the reader will be lit
• Remove the bridge between CLK and DTA lines — the LEDs on the reader will be off, and the
LED OPEN (green) will start flashing
• While the LED OPEN is flashing, read any card — this will be the new MASTER card
• The reader will restart automatically and return to normal mode of operation
