Com4-MATE   Expansion ModuleAll Data Aquisition Boards

High Performance Peripheral Device Controller

There was a time when the RS232 COM port was the dominate interface in PCs, but that has given way to the ubiquitous 'USB' interface. However (the traditional COM port is far from dead), there still exists numerous applications where control of multiple RS232 devices are necessary. The COM4-MATE provides 4 independent RS232 asynchronous communication ports. Many test solutions can be quickly built by connecting the COM4-MATE to a PC laptop or desktop, and then running our GUI software. No external power source is required, since power is supplied through the USB interface. Easy access to the hardware is made available through a convenient collection of boxheaders. There are two options for controlling the COM4-MATE (with a Host PC or embedded microcontroller). In the case of the PC, the COM4-MATE is connected by a USB interface and responds to a simple set of ASCII commands. Programming is easy using Visual BASIC,LINUX, C/C++, LabView, LabWindows or any language that allows access to through a serial port. For embedded operation, the COM4-MATE uses a standard OI interface to allow external control by most popular microcontrollers (i.e., ARM, PIC, AVR or STAMP). Try combining the COM4-MATE with other OI instruments (such as the MiniMATE 'embedded test controller', DVM-MATE 'digital volt meter', Relay-MATE 'signal switcher' and others). Use our ETS Series products to build unlimited test solutions quickly, reliably and affordably.
