[. . . ] The serial I/O signals are 3. 3V CMOS logic level and pins are 5V tolerant. For evaluation and prototype work, it is convenient to have an external RS-232 interface that can connect to the serial port on a PC. The WiPort Evaluation Board has one RS-232 and one RS-232/422/485 transceiver (level shifters) to implement this external interface (only the WiPort 485 supports the RS-422/485 interface). If desired, use the CPs to create a DTE or DCE-style interface using any 3 available CPs. To create these interfaces, connect the signals according to Table 2-3 and Table 2-4. Note: CPx, CPy, and CPz are any of the available CPs. WiPortTM Integration Guide 11 Description and Specifications Table 2-3.

WLAN Signals Pin Number 36 39 Pin Function WLAN Power LED (WiPortB only) WLAN Activity LED WLAN Power LED can be used to drive an external LED to monitor the status of the radio. When the WLAN Power LED is on continuously, it indicates the radio is on and in normal mode. WLAN Activity LED is also used to drive an external LED to monitor the status of the radio. When the LED is blinking, it is receiving or transmitting wireless data. When it is off, it indicates there is no wireless activity. WiPortB WLAN Power LED output can be used to drive an external LED to monitor the status of the radio. WLAN Activity LED output can be used to drive an external LED to monitor the activity of the radio. The output is active when an actual packet is received or transmitted. The LED shall be connected between the output and ground with a series resistor of 220 ohm. WiPortG Pin 36 is reserved. WLAN Activity LED output can be used to drive an external LED to monitor the activity of the radio. The LED shall be connected between the output and 3. 3V with a series resistor of 220 ohm.

[. . . ] CP2 and CP3 not connected to RS-232 transceiver; can function as general purpose I/O pins. CP0 connected to RS232/RS485 select CP1 connected to RS485 2-wire/4-wire select WiPort serial ports connected to RS-232 transceivers. WiPort serial ports 0 and 1 are connected directly to each other through the PLD. Can be used for loopback tests. Note: Other JP7, JP8 jumper configurations are not recognized by the CPLD at this time. [. . . ]
