1.6 Safety
WARNING
Ensure the mains voltage matches the voltage marked on the nameplate.
Ensure the device is provided with its own power supply line and electric fuse.
NOTICE
De-energize the device before working on it.
Switch on the power supply only after completing all works on the device.
NOTICE
Supply voltage may not exceed 33 V. Higher voltage can damage the device.
If the supply voltage is lower than 20 V DC, the device cannot operate properly but will
not be damaged.
NOTICE
If the device is brought from a cold to a warm environment, condensation may form
inside the device. To avoid damage to the device, keep the device in the warm
environment for at least 30 minutes before powering on.

2 Overview
MSD200 is intended for data monitoring and logging in industrial automatic control systems.
The device can operate as Master or Slave via Modbus RTU / ASCII or AKYTEC protocol over
RS485 interface.
The device can be configured with MSD200 Configurator software (free) over USB or RS485
interface (Sect. 4.2). The software can be downloaded from our homepage akYtec.de.
2.1 Basic features
– 4 analog inputs 0-5 mA, 0-20 mA or 4-20 mA.
– Scaling of measured value.
– RS485 (RS1) and USB interfaces to connect to PC.
– RS485 (RS2) interface to connect to other devices in Modbus network.
– Master or Slave in Modbus network.
– Monitoring of data received from other devices via Modbus over RS485 interface.
– Logging and storing the received data to a memory card in a CSV file.
– Remote access over external modem.
–MSD200 Configurator software provides the device configuration and visual tools for process
data analyzing.
– Real-time clock.
– 4 status indicators.
2.2 Design
The device is designed in a plastic enclosure for DIN-rail mounting (Sect. 6).
