ExpertDAQ EX9188E5-M Embedded DOS Controller
Description
Overview
The ExpertDAQ EX9188E5-M is an embedded industrial controller based on the EX-9188 platform, combining a DOS operating environment with Ethernet LAN, 4 RS-232 serial ports, and 1 RS-485 port. It provides 512 k flash memory for the application and 512 k SRAM for runtime data, together with a real-time clock, making it a self-contained platform for data acquisition, protocol conversion, and front-end control applications in industrial networks.
Seven Star LLC supplies the ExpertDAQ EX9188E5-M controller for automation and instrumentation projects across the Sultanate of Oman and the GCC. Water and wastewater, power, oil and gas, and industrial plant rely on embedded controllers for data concentration and protocol conversion, and our team provides genuine ExpertDAQ hardware with regional delivery to Muscat, Sohar, Salalah, and beyond.
Operating Principle
Embedded controllers in the EX-9188 family run user-developed control and communication programs in a real-time DOS environment. The EX9188E5-M communicates with field devices over its serial ports — 4 RS-232 channels for instruments, serial devices, and terminal equipment, plus 1 RS-485 port for multi-drop sensor and I/O networks — and with the wider plant network over Ethernet LAN.
With Modbus support, the controller can act as a data concentrator: gathering values from Modbus field devices on the serial network and making them available to SCADA or the plant LAN, or converting between protocols. The real-time clock timestamps data and schedules control actions without host dependency.
Engineering Design of the ExpertDAQ EX9188E5-M
The EX9188E5-M is designed as a compact embedded platform for DIN-rail or panel installation in industrial cabinets. Its memory architecture — 512 k flash for program and configuration storage and 512 k SRAM for runtime operation — suits data acquisition and communication applications, and the battery-backed real-time clock keeps time through power interruptions.
The combination of Ethernet and multiple serial ports makes the controller a practical building block for small data acquisition systems, front-end processors, and remote terminal units. Programs are developed for the DOS environment, giving engineers direct control over serial timing and protocol handling, which is often required when integrating legacy field devices.
Key Features
The ExpertDAQ EX9188E5-M is specified for embedded control and data concentration applications. Its defining characteristics are:
- Embedded DOS controller from the ExpertDAQ EX-9188 family.
- Ethernet LAN for plant network connectivity.
- 4 RS-232 serial ports for instruments and terminal devices.
- 1 RS-485 port for multi-drop field networks.
- 512 k flash memory and 512 k SRAM for application and runtime data.
- Real-time clock (RTC) for timestamping and scheduling.
- Modbus support for data concentration and protocol conversion.
- Supplied by Seven Star LLC for automation projects across Oman and the GCC.
Industrial Applications
The EX9188E5-M is applied where field devices must be concentrated, converted, or controlled locally. Typical roles include serial-to-Ethernet data concentration for instrument networks, Modbus RTU master or slave front-ends for SCADA, and remote terminal units for monitoring stations in water, power, and process applications. Its multiple serial ports allow several legacy devices to be integrated into modern plant networks without replacing field equipment.
Seven Star LLC supports automation engineers across the Sultanate of Oman and the GCC with the ExpertDAQ EX9188E5-M and the complete EX-9000 series. We provide controllers on request with integration guidance, so that data concentration projects from Muscat to Salalah are built on documented components.

Integration Notes for the EX9188E5-M
Develop the application for the DOS environment with attention to serial port configuration: the 4 RS-232 ports serve point-to-point devices, while the 1 RS-485 port carries multi-drop field networks. With Modbus support, the controller can concentrate data from field devices and serve them to SCADA over Ethernet LAN. The real-time clock timestamps events and maintains time through power interruptions. Seven Star LLC provides integration guidance and genuine ExpertDAQ hardware for projects in Oman and the GCC.

About brand
ExpertDAQ is the name on the EX9000 series of remote I/O modules and converters made by TOPSCCC, a Taipei company founded in 1987. The modules add analog and digital channels to a PC or controller over an RS-485 bus. Seven Star LLC, an independent supplier in Oman, lists the EX9520 isolated converter, the EX9017F analog input module, the EX9044D digital I/O module and the EX9188E5-M embedded controller.
ExpertDAQ EX9000 module families
The manufacturer sorts the EX9000 modules by function: converters, digital input and output modules, relay and solid state output modules, analog input and output modules, and counter and frequency modules. They communicate on RS-485 using Modbus RTU, and a separate group of MTCP models has an Ethernet port. The EX9188 series are small embedded controllers that can run a program locally. A typical small system uses one EX9520 to connect the RS-485 line to a serial port and a row of I/O modules behind it.
Ordering ExpertDAQ modules: what we need
Send the full model number with every suffix letter, since suffixes separate versions with a display, a faster input or a different protocol. State the protocol your software expects, the signal types and ranges, and the number of channels. For expansions of existing panels in the GCC, tell us the modules already on the bus so the new ones are requested with compatible settings.
