matching resistors (terminators) connected at the ends of transmitting lines are not required. In most cases
communication works with any cable type (standard telephone cable, shielded or unshielded twisted pair
etc.) but the recommended cable is unshielded twisted pair (U/UTP cat.5). Shielded cables should be limited
to installations subject to strong electromagnetic interferences. The RS485 communication standard used in
the RACS 5 system guarantees proper communication in a distance of up to 1200 meters as well as high
resistance to interferences.
Communication protocol on RS485 bus of MC16 controller applies proprietary encryption algorithm which is
based on 32b encryption key and it is protected against replication by third party devices.
Note: Do not use more than single pair in UTP cable for RS485 communication bus.
RACS CLK/DTA interface
RACS CLK/DTA interface can be used for communication of controller with older type PRT series terminals.
Up to 4 such devices can be operated via RACS CLK/DTA interface, each with unique address in range of
0-3. Prior to connection of PRT readers it is necessary to make low level configuration of the MC16 and
activate the operation with such readers.
Wiegand interface
Wiegand interface can be used for communication of controller with third party readers. The communication
is performed via controller inputs (IN1-IN8) and up to 4 Wiegand readers can be operated by MC16
controller. Prior to connection of Wiegand readers it is necessary to make low level configuration of the
MC16 and activate the operation with such readers. Input lines which are reserved for Wiegand
communication cannot be used for any other purposes. The controller can operated with Wiegand readers
also via MCX402 and MCX102 expanders.
LED indicators
MC16 controller is equipped with 8 LED indicators on it board. The function of each LED is explained in
table 3.
Inputs
The controller offers 8 general purpose parametric inputs type NO/NC/EOL/DW. Input types and electric
parameters such as response time and parametric resistors are defined within low level configuration
(RogerVDM). Input functions are assigned within high level configuration (VISO). It is possible to double the
number of inputs (3EOL/DW type) and to assign multiple functions to the same input at the same time.
The controller can monitor not only inputs on its board but also inputs located at peripheral devices (MCT,
MCX).
