Claim:
An automatic linking system for multiple consoles, wherein one of the consoles is a master console and the remaining consoles are slave consoles, each console comprising: a master/slave communication end for conveying control command of the master console to the slave consoles; a serial input end for inputting data; and a serial output end for outputting data; wherein the master/slave communication ends of all consoles are in parallel connection; wherein the serial output end of one console is connected to the serial input end of another console to form a console series; wherein the consoles are configured to determine a first slave console if the serial input end of the first slave console is idle in the formed console series, the consoles are configured to determine a master console if the serial output end of the master console is idle in the formed console series; wherein the master console and the first slave console are at opposite ends of the console series; wherein the master console is configured to send a communication protocol data to all slave consoles to set up communication protocol for slave consoles; wherein the first slave console is configured to generate a serial number of one and send the serial number to the second slave console; wherein the second slave console is configured to add one in the received serial number and send the serial number to next slave console; the remaining slave consoles are configured to repeat the operation of adding one to the serial number and sending the serial number to next slave console; wherein the last slave console is configured to send the serial number to the master console whereby the master console identifies the number of slave consoles and assigns station number for the slave consoles.
