It is also possible to communicate with a controller in the system in single mode by sending it a command (with address) to clear the party flag and then communicate with it as in single mode (no line feed terminator) then reset the PARTY Flag when done.

Data Cable lengths greater than 15 feet (4.5 meters) are susceptible to signal reflection and/or noise. IMS recommends 120Ω termination resistors at both ends of the Data Cables. An example of resistor placement is shown in Figure 5.4. For systems with Data Cables 15 feet (4.5 meters) or less, the termination resistors are generally not required.

For more information and other RS-485 termination techniques, search the Internet for "RS-485 Application Notes".
