1
Common voltage reference for the XE900S-500.
2
3.3 Volt power for the XE900S-500.
3 Transmit Data is the data input to the XE900S-500
4 Received Data is the data output from the XE900S-500.
5 Clear to Send provides hardware flow control from the XE900S-500. The XE900S-500
drives /CTS high to signal the host to temporarily stop the flow of data on the /TXD.
6 Request to Send provides hardware flow control from the host system. The host system
drives /RTS high to signal the XE900S-500 to temporarily stop the flow of data on /RXD.
7 DIO3 may be programmed as either a digital input or digital output. It connects directly to
the communications controller in the XE900S-500.
8 DIO2 may be programmed as either a digital input or digital output. It connects directly to
the communications controller in the XE900S-500.
9 DIO1 may be programmed as either a digital input or digital output. It connects directly to
the communications controller in the XE900S-500.
10 DIO0 may be programmed as either a digital input or digital output. It connects directly to
the communications controller in the XE900S-500.
11 Analog Input 1 to the XE900S-500 communications controller. ADC1 connects to an
internal 12-bit Analog to Digital Convertor. ADC0 may also be configured as a digital
input if no analog inputs are required.
12 Analog Input 0 to the XE900S-500 communications controller. ADC0 connects to an
internal 12-bit Analog to Digital Convertor. ADC0 may also be configured as a digital
input if no analog inputs are required.
