Model 263 Application Notes

The heavy manufacturing environment is replete with examples of machine tools, instruments and other devices being employed and often under the control of a PC. Such control can be effected by linking the PC and these devices by data communications. However, interface conversion is usually needed to effect the communications. Data generally comes into and out of the PC through an RS-232 interface. On the other hand the tools, instruments and other devices may employ the RS-422 interface, which uses differential signaling to combat the high electrical noise prevalent when high current machinery is in operation.

The Model 263 provides the needed interface conversion for the manufacturing plant. It provides the needed interface conversion, full duplex, at any allowed data transmission rate. The Model 263 will do this over 8,000 feet of twisted pair cable into a load of 120 Ohms. It has some additional features which make it attractive not only for the factory floor, but for other settings as well.

The Model 263 has built-in surge protection. It is also non-powered. It needs neither AC nor DC power, but powers itself from the connected RS-232 interface. This is particularly convenient when wall outlets are not readily available.

The illustration above shows a ready application for the Model 263 - a factory machine tool being controlled by a PC.
