The MAX14830 EV kit provides a proven design to
evaluate the MAX14830 IC. The IC is an advanced quad-
channel UART with each UART containing 128 words of
receive and transmit FIFO buffer that can be controlled
through SPI or I
through SPI or I
Each of the four UARTs can interface with an IO-Link
master transceiver or an RS-485/RS-232 multiprotocol
transceiver. The EV kit contains four on-board IO-Link
master transceivers, four RS-485/RS-232 multiprotocol
transceivers, and 8-channel DPDT switches to select
between the IO link and RS-485/RS-232 transceivers.
Jumper JU1 selects the IC’s operating mode. The operat-
ing mode is selectable between SPI and I
2 for JU1 shunt positions.

Jumper JU2 selects the IC’s output interface. The output
interface is selectable between the IO link and RS-485/
RS-232 transceivers. See Table 3 for JU2 shunt positions.
Jumpers JU3–JU10 connect or disconnect the IO-Link
signal (C/Q)/(DI) from their respective LED indicators.
Install shunts to connect or remove shunts to disconnect
the IO-Link signal from their respective LED indicators.
Table 4 lists the correspondence between jumpers
JU3–JU10 to their respective IO-Link signal and LED
indicators.
Jumper JU11 selects the destination for the CSN (chip-
select signal on the SPI/I2C header, pin 5). The CSN
chip-select signal can be set to serve either the UART
(MAX14830) or the four IO links (MAX14824) using JU11.
See Table 5 for JU11 shunt positions.
