Serial Interface
The M1280 is typically used with RS-232, RS-485 and IR transceivers. The following figure shows typical
connections from the UART to the different transceivers. For more information on RS-232 and RS-485/422
transceivers, go to www.exar.com or send an e-mail to uarttechsupport@exar.com.
