MedLAN Connector (on the weld processor card):
WA R N I N G!
NEVER connect any of the communication ports
to the MDP- power wires. Damage to the ports or
other internal components may result.

Wire the MedLAN network ONLY in a “daisy-chain” method. NEVER
use “stub” wiring.
The maximum total length of the MedLAN network cable is 3,000 feet.
Up to 30 weld controls may be connected to a single MedLAN network.
The MedLAN cable wire ends terminate into MTSB (Phoenix)
connectors. Terminate the cable with this procedure:
1. Strip the cable jacket to 1 inch.
2. Remove foil shield strands outside the foil.
3. Cover the shield with heat shrink.
4. Cover the cable insulation end with one inch of heat-shrink tubing.
5. Strip 1/4 inch of insulation off each wire.
