Roger RUD-1 Portable USB-RS485 communication interface
RUD-1 is an optional, universal, portable, hardware communication interface
(USB/RS485) dedicated to Roger access control devices. It is designed for
installers, who use laptops to configure and manage controllers and readers
made by Roger. It has small dimensions and can be easily connected to USB port.
RUD-1 includes built-in 12VDC/120mA converter, which can be used to supply
power to programmed device (controller or reader). RUD-1 also does not require
power supply unit as it draws power from USB port.
RUD-1 can be used in following scenarios:
- Communication with RACS 4 system as USB-RS485 converter
- Configuration and management of particular PRxx1 and PRxx2 series
controllers by means of PR Master software
- Configuration and management of PRTxxEM and PRTxxMF series readers by
means of RARC software
- Firmware update of PRxx1 and PRxx2 series controllers by means of Roger
ISP software
- Firmware update of PRTxxEM and PRTxxMF series readers by means of Roger
ISP software
- Third party applications as USB/RS485 or USB/RS232 converter
RS485 lines fully support RS485 electrical standard. The data flow
control is provided by the internal logic of the RUD-1 using following formula:
the RS485 circuit automatically switches to transmit mode when data comes from
the PC and returns to receive mode when transmission from PC completes.
TXD and RXD lines are used for serial communication between programmed
reader and PC in RS232 standard.
RTS and CTS lines can be optionally used for operation of RUD-1 with
RACS4 system and are intended to improve effectiveness of the data flow between
PR Master software on the PC and Roger Access Control System. These lines can
improve the transmission if the system consists of at least 15-20 controllers
and CPR-32SE network controller.
RUD-1 can be used in Roger system as well as in third party applications as
USB/RS485 and USB/RS232 converter.
RUD-1 is compatible with following version of software:
- PR Master v4.3 or newer
- RARC v1.3 or newer
- RogerISP v4.0 or newer
