3. Fail safe bias resistors are used to bias the TX TX and RX RX lines to the correct state when these lines are not being actively driven This is an important consideration since in a typical RS 485 installation the RS 485 drivers are frequently tri stated If fail safe bias resistors are not present the 485 bus may be floating and very small amounts of noise can cause spurious characters at the receivers 4 7KW resistors are used to pull the TX and RX signals to 5V and also to bias the TX and RX signals to ground Termination resistors in many installations are not required when cable lengths are less than 50 meters and the baud rate is 9600 or less Termination resistors may be required for reliable operation when running longer distances or at higher baud rates Termination resistors typically 100 150 ohms should only be installed at each end of an RS 485 transmission line In a multi drop application where there are several drivers and or receivers attached only the devices at each end of the transmission line pair should have termination resistors A read at I O location 0x2240_0000 bit 1 will return a 1 when the RS 485 option is installed 3 4 RS 485 Quick Start Procedure Perform the following steps 1 Check that the RS 485 option is installed in the TS 7200 required 2 Attach the RS 485 cable to the 10 pin header Adaptor cables to SubDB9Y connector are available from Technologic Systems 3 Set the COM2 UART se
