FX-485ADP COMMUNICATION ADAPTER FX0N-485ADPCOMMUNICATION ADAPTER USER'S GUIDE JY992D53201C This manual contains text, diagrams and explanations which will guide the reader in the correct installation and operation of the FX and FX0N, 485 communication adapters. It should be read and understood before attempting to install or use these units. Further information can be found in the FX PROGRAMMING MANUAL, FX and FX0/FX0N series hardware manuals.
INTRODUCTION 1 The adapter for FX-485ADP RS485 or the adapter for FX0N-485ADP RS485 (both called 485ADP hereinafter) 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.

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.
