RDR2S-A ADDRESS MODE AND PERFORMANCE
The following graph presents RDR2S-A performance data in physical versus
legacy address mode. The data was derived by connecting a specified number
of modules on the RS-485 bus and measuring the response time between
reading two badges by two readers on the same module and unlocking two
doors.
