Trilogy Touch Technology Trilogy Commander Digital Intercom 9 Manual Do Utilizador

 

 

The current version of PC connector plate, which is fitted on the rear right hand side of the 
Commander Matrix frame, provides either RS232 or RS422 connection capability. The 
factory default setting is RS232: this may be changed by removing the 4 fixing screws, 
withdrawing the rear connector assembly and moving the PCB mounted jumper links to the 
alternate position. Most computers are fitted with D9 fixed sockets for the serial COM port. 
For older models equipped with a D25, suitable adaptors may be easily obtained.
