The IRV-3702 SBC contains a Realtek RTL8139 highly integrated single-chip Fast Ethernet controller.  
The RTL8139 provides 10Mbps and 100Mbps auto-sensing operation, PCI bus master capability, and 
full compliance with IEEE 802.3u 100Base-TX specifications. The RTL8139 keeps network maintenance 
cost low and eliminates usage barriers. It also supports full-duplex operation, making possible 
200Mbps of bandwidth. Refer to Appendix D for connector location and pin assignments.  For more 
information on the Realtek Ethernet controller contact their web site at http://www.realtek.com.tw.

The IRV-3702 SBC contains a built in IrDA infrared interface port which supports Serial Infrared (SIR) 
or Amplitude Shift Keyed IR (ASKIR) interfaces. The IrDA port is addressed as COM2 and must be 
setup in the BIOS’ Peripheral Setup. When the IrDA port is enabled, the standard COM2 serial port is 
disabled. Refer to Appendix D for connector location and pin assignments.

 Key 1K-bit electrically eraseable memory. This memory is useful for 

storing user data such as password, terminal address, configuration parameters, etc. The memory is 
configured as 64 words, which can be accessed a word at a time, and uses the parallel port for the 
hardware interface. Software utilities are provided on the distribution disk that includes a demo 
program, and two C library functions for integrating into your application program.
