900 Series Industrial Ethernet Switches
The 900 Series Modular Industrial Ethernet Switches support high speed layer 2 switching between ports.
The 900B and 900N enclosures contain a three slot backplane that supports up to three modules. The
908TX, 902FX and 904FX modules are the available modules. The N-TRON Corp. 900B is housed in a
ruggedized steel enclosure, and can withstand industrial temperatures, as well as extreme shock & vibration.
The 908TX is an 8 port module that is capable of auto negotiating 10/100 Mb and half/full duplex
communications. The N-TRON 908TX also supports MDIX auto sensing (for auto connector of straight
through or crossover cables) and provides 8 Category 5 compliant 10/100-BaseT connections for high
performance network design, and hub/repeater upgrades.
The 902FX is a two port 100Mb module that supports multimode fiber. ST and SC connectors are
available.
The 902FXE is a single mode (laser) version of the 902FX, and can support distances of up to 80km.
The 904FX and 904FXE are four port versions of the 902FX and 902FXE respectively.
Key Features
•Full IEEE 802.3 & 100BASE-FX Compliance
•Extended Environmental Specifications
•Support for Full/Half Duplex Operation
•LED Link/Activity Status Indication
•Auto Sensing Speed and Flow Control
•Auto MDIX (908TX only)

902FX/FXE & 904FX /FXE HALF DUPLEX SETUP
All 900 series fiber modules are factory configured for full duplex operation. The setting is controlled
by jumper JP1 on the backplane.
Note: Most 100Mbit fiber systems will be compatible with this Full Duplex setting. If Half Duplex
operation is desired, then follow these steps using proper wrist strap grounding techniques:
1. Remove the power & power plugs from the unit.
2. Loosen all thumbscrews & remove all modules.
3. Remove the six screws holding the backplane
4. Remove the backplane.
5. Move the jumper JP1 from position 1-2 to 3-4
6. Re-install the backplane & modules & power plugs.
902/904 Note:
Rev. C & D boards are hard wired for Port1 = HDPLX,
Rev. B & E boards are hard wired for Port1 = FDPLX.
