1. Introduction
Transition Networks hardened serial device server provides the ability to communicate secured serial data across
an Ethernet network.
The SDSTX3110-121S-LRT contains two 10/100 Fast Ethernet ports that can be configured to communicate to
one or multiple redundant servers. Security of the data transmission is assured through HTTPS, SSH, and SSL data
encryption.
The SDSTX3110-121S-LRT comes with COM port redirector software enabling communication of serial data to a
virtual COM port on a server, or can be used in pairs to provide serial tunneling across the Ethernet network.
The SDSTX3110-121S-LRT is a hardened device designed to operate in the harshest environments. It has a slim
IP-30 enclosure that can fit into space-constraining cabinets. The device accepts 12-48VDC power input and it is
also certified to operate in temperatures of -40°C to +70°C.

2.1.6 DIP Switch for RS 422/485 Termination
Termination is used to match the impedance of a transmission line to the hardware impedance of the interface it
is connected to. There is more than one way to add termination to an RS485/422 serial connection. The most
commonly used is DC Termination, accomplished by attaching a resistor between the signal lines on the extreme
ends of the transmission line.
Set DIP switch # 3 to ON (enabled) for long distance (>=100m) transmission to improve the quality of data
transmission. The default is Off.
SW No.

The SDS can be fixed to the wall via the wall mount kit included in the package. The wall mount kit dimensions
are provided below.
To install the device on a panel or wall:
1. Remove the Din-Rail clip by removing the three screws.
2. Use the screws included in the package to install the wall mount bracket.
3. Screw the two pieces of wall-mount kits to the top and bottom panels of the device. A total of eight screws
are required, as shown below.
4. Use the device, with wall mount plates attached, as a guide to mark the correct locations of the four screws.
5. Insert a screw head through middle of the keyhole-shaped aperture on the plate, and then slide the device
downwards. Tighten the screw head for added stability.

3.4 Wiring
Warning: Do not disconnect modules or wires unless power has been switched off or the area is known
to be non-hazardous. The devices may only be connected to the supply voltage shown on the type plate.
Attention:
1. Be sure to disconnect the power cord before installing and/or wiring your devices.
2. Calculate the maximum possible current in each power wire and common wire. Observe all electrical codes
dictating the maximum current allowable for each wire size.
3. If the current goes above the maximum ratings, the wiring could overheat, causing serious damage to your
equipment.
4. Use separate paths to route wiring for power and devices. If power wiring and device wiring paths must
cross, make sure the wires are perpendicular at the intersection point.
5. Do not run signal or communications wiring and power wiring through the same wire conduit. To avoid
interference, wires with different signal characteristics should be routed separately.
6. You can use the type of signal transmitted through the wire to determine which wires should be kept
separate. The rule of thumb is that wiring sharing similar electrical characteristics can be bundled together.
7. You should separate input wiring from output wiring.
8. It is advised to label the wiring to all devices in the system.
3.4.1 Grounding
Grounding and wire routing help limit the effects of noise due to electromagnetic interference (EMI). Run the
ground connection from the ground pin on the power module to the grounding surface prior to connecting
devices.
3.4.2 Redundant Power Inputs
The device has two sets of DC power inputs on the 4-pin terminal block located on top of the device. Follow the
steps below to wire the power input on the terminal block.
1. Insert the Terminal Block connector into the keyed receptacle on the SDS.
2. Insert the negative/positive wires into the V- and V+ terminals, respectively.
3. To keep the wires from pulling loose, use a small flat-blade screwdriver to tighten the wire-clamp screws on
the front of the terminal block connector.

3.5 Connection
3.5.1 10/100BASE-T(X) Pin Assignments
Depending on the link type, the device can use CAT 3, 4, 5, or 5e UTP cables to connect to any other network
devices (PCs, servers, switches, routers, or hubs). See the table below for cable specifications.
With 10/100BASE-T(X) cables, pins 1 and 2 are used for transmitting data, and pins 3 and 6 are used for receiving
data. Note that the + and -signs represent the polarity of the wires that make up each pair.
