	This is Tern's TD86 Embedded controller. It is based on the 186 processor. Including the TD keyboard known as a TD Pack They carry a diverse range of controllers.
	This is a view of it with the TD Pack removed. The TD86's technical information is here. or the manual here TD86 Specs: * Measures 4.8x3.4x0.5 inches * 16-bit CPU (186), x86 compatible * 40 MHz system clock * Power consumption: 190/130 mA at 5V * Power saving mode: 30/25 mA at 5V * Power input: +8.5 to +12V linear regulator, * +8.5 to +35V switching regulator * Temperature: -40 to +85 Celsius * 16-bit external data bus * Up-to 256 KW (512 KB) Flash, 256 KW SRAM onboard. * 16 ch. 300 KHz 12-bit ADC, 0-5V input * 4 ch. 200 KHz 12-bit DAC, 0-2.5V out * Four serial ports, supporting RS-232/RS-485/RS-422. * Six 16-bit timers/counters * 16 opto-coupler inputs, including 5 external interrupts. * Real time clock, battery, switching regulator.
This was used to build a custom data bridge between Fuji PYX9 Temperature controllers and the Automation Direct PLC control and data acquisition system. The TD86 communicates to the Fuji PYX9's using Fuji's communication protocol. It pulls the Set Value, Process Value and Deviation Value and stores them in its memory. Then it communicates to the Automation Direct P.L.C. using the K-Sequence protocol and puts the values into the P.L.C.'s V memory.
