Reader Wiring Configurations
You can wire RM readers in a multidrop or star configuration. A
multidrop line uses an RS-485 bus to connect up to two readers and up to
four I8 Input Modules and up to four R8 Output Modules to the apC/L
reader port. See Figure 4.2 for an illustration.
The star configuration is the simplest way to connect readers to an apC/L.
An RS-485 bus connects each single reader to its own port on the apC/L.
