Instruction manual
Auto-
Negotiation
The iMcV-Giga-MediaLinX ships from the factory with Auto-
Negotiation enabled on the twisted pair port. In this mode,
the twisted pair port negotiates for speed and duplex,
autosensing 10 Mbps Full-Duplex, 10 Mbps Half-Duplex,
100 Mbps Full-Duplex, 100 Mbps Half-Duplex with Flow
Control, or 1000 Mbps Full-Duplex with Flow Control.
Configure Auto-Negotiation by setting the DIP switch (for
unmanaged modules) or via the management software.
Selective
Adverting
Selective Advertising, when used in combination with Auto-
Negotiation, advertises only the configured speed and
duplex mode for the twisted pair port. This allows
configuration of both the twisted pair port’s speed (10, 100
or 1000 Mbps) and Duplex mode (FDX or HDX).
Selective Advertising (switch 7) functions only with Auto-
Negotiation (switch 1) enabled.
Selective Advertising Configuration
Desired Speed/Duplex Switch 2: Duplex Switch 3: Speed Switch 4: Speed
1000 Mbps FDX OFF OFF ON
100 Mbps FDX OFF ON OFF
100 Mbps HDX ON ON OFF
10 Mbps FDX OFF OFF OFF
10 Mbps HDX ON OFF OFF
Forcing the
Duplex Mode
The twisted pair port on the iMcV-Giga-MediaLinX can be
set to either Half- or Full-Duplex operation in 10/100 Mbps
(1000 Mbps is always FDX). Before manually setting the
duplex mode, disable Auto-Negotiation by setting DIP
Switch 1 to OFF.
•
The twisted pair port is configured for Full-Duplex
by default, which is the OFF position on DIP
Switch 2.
•
Configure the twisted pair port for Half-Duplex by
setting DIP Switch 2 to the ON position.
Forcing the
Speed
The speed on the twisted pair port (10, 100, or 1000 Mbps)
can also be manually configured. (The fiber port always
operates at 1000 Mbps/FDX.) Before manually setting the
speed mode, disable Auto-Negotiation by setting DIP Switch
1 to OFF.
•
Configure the twisted pair port for 10 Mbps
operation by setting both DIP Switches 3 and 4 to
5
