An IR and RS-232 typical operating circuit is shown in
Figure 14. Since the MAX3110E/MAX3111E’s internal
UART has IrDA capability, a standard IR transceiver
(the MAX3120) can be used to provide the IrDA com-
munication. The two-driver/two-receiver RS-232 trans-
ceiver can be used with a software UART to provide
RS-232 communication.
The MAX3110E/MAX3111E support a common multi-
drop communication technique referred to as 9-bit
mode. In this mode, the parity bit is set to indicate a
message that contains a header with a destination
address. The MAX3110E/MAX3111E’s parity mask can
be set to generate interrupts for this condition.
Operating a network in this mode reduces the process-
ing overhead of all nodes by enabling the slave con-
trollers to ignore most message traffic. This relieves the
remote processor to handle more useful tasks.
