The green led is fixed, and signals the correct connection of the module.
The yellow led blinks when there is activity (data IN/OUT) on the net connection.
With RJ45 connectors, only twisted pair cables can be used.
Important Note. Connection to a 100BASE-TX hub for 100 Mbps operation requires Cat. 5
Unshielded Twisted-Pair (UTP) cable or Cat. 5 Shielded Twisted-Pair (STP) cable. The
maximum length between the 100BASE-TX hub and the adapter is 100 meters.
Connection to a 10BASE-T hub for 10 Mbps operation requires a Cat. 3, 4, 5 UTP cable or
Cat. 5 STP cable. Preferred maximum cable length between SpacePC 1232 module and
Ethernet adapter is 10 cm (4”)
The SpacePC 1232 module features a single-chip Fast Ethernet controller that provides 32-bit
performance, 10/100Mbps auto-sensing, PCI bus master capability, and full compliance with
IEEE 802.3u 100Base-T specifications and IEEE 802.3x Full Duplex Flow Control.
Net drivers
The available drivers are supplied in a CD-ROM coming with the SpacePC 1232 module. There
are several OSs supported by the RTL8139 Ethernet controller. Check the Parvus web site in
order to get the latest information on driver availability for your operating system.
