19-6127; Rev 1; 7/12 MAX14830 Evaluation Kit Evaluates: MAX14830 General Description The MAX14830 evaluation kit (EV kit) provides a proven design to evaluate the MAX14830 quad-channel universal asynchronous receiver-transmitter (UART) IC. Each UART contains 128 words of receive and transmit first-in/ first-out (FIFO) buffer that can be controlled through the SPI or I2C interface. Each of the four UARTs are selected through SPI or I2C in-band addressing. Each of the four UARTs can interface with an IO-LinkM master transceiver or an RS-485/RS-232 multiprotocol transceiver. The EV kit contains on-board IO-Link master transceivers, RS-485/RS-232 multiprotocol transceivers, and double-pole/double-throw (DPDT) switches are used to select between the IO link and RS-485/RS-232 transceivers.

System Setup Example 3 MAX14830 Evaluation Kit Evaluates: MAX14830 Detailed Description of Hardware The MAX14830 EV kit provides a proven design to evaluate the MAX14830 IC. The IC is an advanced quadchannel UART with each UART containing 128 words of receive and transmit FIFO buffer that can be controlled through SPI or I2C. Each of the four UARTs is selected through SPI or I2C in-band addressing. 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 Selection SPI/I2C Operating Mode (SPI/I2C) Jumper JU1 selects the IC's operating mode. The operating mode is selectable between SPI and I2C. See Table 2 for JU1 shunt positions. IO Link and RS-485/RS-232 Output Interface Selection (INA) 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. IO-Link Signal Indicators ((C/Q)/(DI)) 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. UART and IO-Link Chip-Select Signal (CSN) Jumper JU11 selects the destination for the CSN (chipselect 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. Table 2.
