2.1.3 User LAN Ports
The WC-Serial has two User LAN ports presented on RJ45 connectors. The two
ports support 10/100BaseT with auto MDI/MDI-X crossover switching. The ports are
configured as a pair using the bit switches on the underside and therefore may be
manually configured with auto negotiation disabled.
The two LAN ports are connected internally via a wirespeed switch and so local
switching is supported.
2.1.4 Multi-Protocol Serial Port
The multi-protocol serial port is presented on a HD60 connector. The pinout is
compatible with Cisco, and as such uses the following conversion cables to present
the required DTE or DCE interfaces
DTE
DCE
X.21
CAB-X21-MT
CAB-X21-FC

Please note that DCE operating modes have a fixed data rate of 2.048Mbps and are
for lab testing purposes.
2.1.5 RJ45 Led Indicators
Each RJ45 connector has two LED’s, one green and one yellow and these are
combined to show the Link State, Link Activity and Link Speed as shown below:
The Green LED is used as a Link/Activity indicator. If the LED is off there is no link.
If the LED is on the link is up but there is no activity. If the green LED is flashing the
link is up and data is passing.
The Yellow LED is used to indicate port speed.
All LED’s off indicates the link is down.
