Product Features
Front panel
The MIL-FT240TX has three 10/100Base-T(x) ports.
Auto-Negotiation
(selectable)
The Auto-Negotiation feature automatically configures the transceiver to achieve
the best possible mode of operation over a link. The transceiver broadcasts its speed
(10 Mb/s or 100 Mb/s)
and duplex capabilities
(full or half)
to the other devices and
negotiates the best mode of operation. Auto-Negotiation allows quick and easy
installation because the optimal link is established automatically—no user
intervention required.
In a scenario where the media converter is linked to a non-negotiating device, the
user may want to disable Auto-Negotiation. In this instance, the mode of operation
will drop to the least common denominator between the two devices
(e.g., 10 Mbs,
half-duplex).
Disabling this feature gives the user the ability to force the connection
to the desired speed and duplex mode.
Data Transfer rate
(selectable)
10Base-T data transfer rate: 10 Mbps baseband Ethernet
100Base-TX data transfer rate: 100 Mbps baseband Ethernet
Full-Duplex network
(selectable)
In a full-duplex network, maximum cable lengths are determined by the type of
cables used. The 512-Bit Rule does not apply in a full-duplex network.
Half-Duplex network
(selectable) (512-Bit Rule)
In a half-duplex network, the maximum cable lengths are determined by the round
trip delay limitations of each fast Ethernet collision domain.
(A collision domain is
the longest path between any two terminal devices, e.g., terminal, switch, or router.)
The 512-Bit Rule determines the maximum length of cable permitted by calculating
the round-trip delay in bit times (BT) of a particular collision domain. If the result is
less than or equal to 512 BT, the path is good.
AutoCross™
When the AutoCross feature is activated, it allows either straight-through MDI or
crossover MDI-X cables to be used when connecting to 10Base-T or 100Base-TX
devices. AutoCross determines the characteristics of the connection and
automatically configures the unit to link up, regardless if the cable configuration is
MDI or MDI-X. This feature is ON permanently.

Installation
CAUTION: Do Not install the MIL-FT240TX transceiver in location where it might be
exposed to wetness. Failure to observe this caution could result in damage to the
transceiver.
Set DIP Switch
Four (4) Dip Switches
• SW 1: Auto-Negotiation
• SW 2: Speed
• SW 3: Duplex
• SW 4: Not Used
Note
: See the diagrams below and use a very small flatblade screwdriver or similar
device to set the DIP switch.
When Auto-Negotiation is enabled
(switch #1 UP)
, the transceiver
advertises all rate and mode capabilities to the network: 100Mb/s full
duplex, 100Mb/s half-duplex, 10Mb/s full duplex, and 10Mb/s half
duplex.
Note:
Switches “#3” and “#4” are non-functional when switch “#1” is in the UP
position
(Auto-Negotiation enabled).
When auto-negotiation is disabled
(switch #1 DOWN)
, the transceiver
does not advertise rate and mode capabilities to the network.
100Base-TX data transfer rate
(switch #2 UP)
: 100 Mbps fast
Ethernet.
