1 INTRODUCTION
The Metrodata WC-Serial is a two port auto sensing 10/100BaseT Ethernet Switch
with a multi-protocol serial uplink. The WC-Serial can be used to extend two LAN
ports across a serial WAN link to a remote site. Each LAN port may be connected
to a single LAN workstation or to a hub or switch supporting multiple workstations.
The exact configuration will depend upon the user’s network design and workload
characteristics.
An example application is shown below, where a remote office with two users is
connected to the head office servers via a BT Kilostream X.21 service.
The WC-Serial Ethernet Switch can switch between local LANs connected to its two
ports, and the unit may thus reduce the need for local LAN hubs and switches. The
Ethernet switch has full wirespeed filtering so that the WAN serial port carries only
traffic destined for the remote WAN-linked site, and an efficient HDLC encapsulation
of packets ensures maximum throughput over the WAN link. There is internal packet
buffering to smooth out bursty traffic. WC-Serial units are used in pairs, one on either
side of a WAN link due to the proprietary encoding of the serial data.
The serial port uses a HD60 connector and is compatible with the Cisco HD60 cable
set to support DTE interfaces at X.21, EIA-530 or V.35.

1.1 WC-Serial
The WC-Serial is a compact unit as shown occupying half a shelf in a traditional
19inch rack. All connectors and LED status indicators are accessible from the rear
of the unit.
1.2 Safety
The WC-Serial must not be connected to cabling which would be required by
BS6701 to equipped with over voltage protection. The following ports on the
FCM5000 are designated SELV ( Safety Extra Low Voltage ) within the scope of
EN41003
Terminal RJ45
LAN Port(s) RJ45 10/100BaseT
These ports must only be connected to SELV ports on other equipment in
accordance with EN60950 clause 2.3
1.3 Electro Magnetic Compatibility
In order to ensure EMC compliance, all signal and data cables must be shielded and
use screened connector shells. The cable screens must be terminated to the
screened connector shell and not connected to any pins of the connector. Failure to
use the correct connectors may compromise EMC compliance.

1.3.1 EN55022 Statement
The WC-Serial is a Class A product. In a domestic environment, this product may
cause radio interference, in which case the user will be required to take adequate
measures.
1.3.2 FCC Declaration
This equipment has been tested and found to comply with the limits of the Class A
digital device, pursuant to Part 15 of the FCC rules. These limits are designed to
provide reasonable protection against harmful interference when the equipment is
operated in a commercial environment. This equipment generates, uses and can
radiate radio frequency energy and, if not installed and used in accordance with the
Installation and Operation manual, may cause harmful interference to the radio
communications. Operation of this equipment in a residential area is likely to cause
harmful interference in which case the user will be required to correct the
interference at his own expense.
1.4 WEEE Directive
The WC-Serial is covered by Directive 2002/96/EC ( OJ:L37/24/2003 ) on Waste
Electrical and Electronic Equipment ( WEEE ) Units must therefore not be disposed
of in standard landfill.
1.5 RoHS Compliance
The WC-Serial is compliant with the EU RoHS Directive 2002/95/EC. The RoHS
directive bans the use of six hazardous materials in products placed on the market
after July 1st 2006. The six banned materials are Lead, Mercury, Hexavalent
Chromium, Polybrominated Biphenyls, Polybrominated Diphenyl Ethers and
Cadmium.
The FCM5000 is manufactured using a lead free soldering process and as such is
fully RoHS 6/6 compliant.

2 INSTALLATION
2.1 WC-Serial Rear Panel
The WC-Serial is available with either AC Mains or DC power options.
2.1.1 Mains Power
The WC-Serial has an internal power supply and is supplied via an IEC mains power
socket. The WC-Serial operates over the wide range 100 to 250V AC and draws
less than 6 watts.
2.1.2 DC Power
The WC-Serial is available with an internal DC power supply with two variants
available,
DC -48V ( 36 to 72V DC )
DC 24V ( 7 to 36V DC )
DC powered units have an external earth stud which must be securely connected to
an earth connection to ensure EMC compliance.

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
EIA-530 CAB-530-MT CAB-530-FC
V.35 CAB-V35-MT CAB-V35-FC
V.36 (RS449) CAB-449-MT CAB-449-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.
