The adapter for FX-485ADP RS485 or the adapter for FX is designed to link the data between PC and computer by using 485PC-IF. (1)Data exchange by request from computer Specified data can be exchanged by sending a request command from the computer to the PC. Except for few functions (global function, on-demand function), the program for data link is not needed at the PC side.
1.2 System configuration The system configuration of computer and PC is either 1 : 1 or 1 : n, and for communication with the computer, the RS-485 or RS-422 is used. (1) Computer and PC by 1 : 1 configuration Computer 485PC-IF (2) Computer and PC by 1 : n configuration...

The terminal lagout shown is diagrammatic only.
2.3 Terminating resistances The terminating resistances are resistances connected between terminals SDA and SDB, and between terminals RDA and RDB at both end stations of the circuit (or the interface when an interface such as 485PC-IF is used at both end stations), when connecting with the RS-485 or RS-422 circuit. For connection examples, see section 2.1 and 2.2.
