GE mass-produced the DS215UCVEH2A EX2000 Ground Detector and Oscillator as a part of their Mark VI series of Speedtronic turbine system controllers. It is now considered to be a legacy series and no longer receives any support from General Electric. Though it may be hard to find, AX Control still attempts to keep it in stock.
The DS215UCVEH2A is a UCVE-type controller. This board has an Intel Celeron 300 MHz microprocessor and a QNX operating system. It has 32 MB of DRAM, 16MB of compact flash memory, 128 KB L2 cache, and a battery backup SRAM. This controller can also support Profibus.
The DS215UCVEH2A has many different features on its faceplate. There are three status LEDs that will glow when it detects different things. The first indicates when it detects a VME bus system failure. The second will glow when it detects flash activity. The third will glow when it detects power going to the controller. Below these LEDs is an SVGA port that is used as a GE monitor port. Below the port is an M/K connection that is used to attach a keyboard or a mouse. Below that are two miniature 9-pin RS-232C ports. One port is used for serial communication and the other is used to set up the controller. Below these ports is a LAN Ethernet port. This port has two status LEDs attached to it that will monitor the port’s active status and its link status. Below that is an RST LED indicator followed by a PC MIP and Mezzanine connection.
