Chapter 2 Installation In this chapter you will learn how to e set the module configuration switches e mount the Serial Communications Module e connect the cables e connect the SCANport link e connect the power supply Read this chapter completely before you attempt to install or configure your Serial Communications Module Double check all connections and option selections before you apply power Important Switch selections take effect only on power up If you change selections after power is applied cycle the power to use the new settings When making configuration changes to the Serial Communications Module use the addressing conventions of the PLC SLC processor or serial device through which you are communicating In all cases each serial device must have a unique address that the target processor can recognize ATTENTION When changing the switch settings use a blunt pointed instrument such as a ball point pen Do not use a pencil because the lead graphite of the pencil may damage the switch assembly ATTENTION Failure to check connections and switch settings for compatibility with your application when configuring the communications module could result in personal injury and or equipment damage due to unintended or undesirable operation ATTENTION It is recommended that when a system is configured for the first time you should disconnect the motor from the machine or process during the initial testing
