The TEF20 series of analysers were made by the Techron division of Crown and more recently by Gold-Line. The earliest TEF20 and TEF20A versions had only serial interfaces. Then came TEF20PC later called TEF20HI which added a high speed interface using a ISA card that fit in a Windows PC slot. More recently came the TEF20SHIP which added a parallel port interface capability to the serial and high speed interface ports. Today since parallel ports are getting rare on Windows PCs and in particular on laptops, there is a USB adaptor for all but the early serial port only versions of the TEF20. The USB adaptor will work with the current generation Windows based software modules, but not with the old DOS software modules.
