And what products are they?
The first of them is the DDC controller mark130 – a freely programmable controller with an ARM Cortex M4 processor and OS FreeRTOS and serves as a replacement for mark125. It is suitable for controlling smaller applications or as a terminal for displaying values from other mark process controllers with Merbon runtime. It contains 1x Ethernet port, 1x RS485 interface, 1x RS232 interface and external 8 MB RAM.
HT104 user terminal is an interface for controlling and monitoring DDC mark/wall controllers with the Merbon runtime, which replaces former HT102. It is equipped with an Ethernet interface. It is controlled by six buttons and a backlit LCD display of 4 × 20 characters. Ethernet can be used to communicate with the controllers. The PWR LED is used to indicate power supply and the RUN LED to indicate program run. DIP switch 3 in the ON position at start sets the default IP address and does not start recording the menu configuration, thus enabling service access to the terminal in the event of a damaged menu file (so-called INIT status). Switch 4 in the ON position at startup blocks web and FTP access. This feature can be used for higher network security.
