| description | The utility model has the high communication speed, stability and reliability and high load ability. A EMC (electromagnetic compatibility) designs the circuit under the auxiliary of a universal PIC interface chip, a dual port RAM chip, a buffer, a microprocessor, a RS485 drive chip and a SRAM chip; the device can carry out the data communication downwards together with a plurality of intelligent controllers (equipment) connected with the device and is upwards connected with a PC computer through a PIC bus, achieving that the PC device carries out the high speed communication with the intelligent controllers (equipment) at the same time. The program designed and embedded in the intelligent converting device achieves the functions of the check data, conversion data and temporary storage data. |
