Getting Started
1.1 About the TPS-3882GT-M12-BP1 Series
The TPS-3882GT-M12-BP1 series, including the TPS-3882GT-M12-BP1,
TPS-3882GT-M12-BP1-24V models, are managed Ethernet switches designed for industrial
applications, such as rolling stock, vehicle, and railway applications. The switches boast
EN50155 compliance and M12 connectors to ensure tight and robust connections, and
guarantee reliable operation against environmental disturbances, such as vibration and shock.
All models feature eight 10/100Base-T(X) P.S.E. ports which are able to provide sufficient
power for power-hungry devices. Therefore, you can attach an IEEE 802.3af-compliant device
to the switch without requiring additional power. The devices also provide 1 set of bypass ports
that ensure constant network connectivity if power outage or node failure occurs. In such
situations, the device will bypass the inactive switch and continue to transfer network traffic to
the next switch in the relay. With complete support for Ethernet redundancy protocols such as
O-Ring (recovery time < 30ms over 250 units of connection) and MSTP (RSTP/STP
compatible), the switches can protect your mission-critical applications from network
interruptions or temporary malfunctions with fast recovery ability. Featuring a wide operating
temperature from -40oC to 70oC, the series can be managed centrally via Open-Vision, web
browsers, Telnet and console (CLI) configuration.

Instead of screwing the screws in all the way, it is advised to leave a space of about
2mm to allow room for sliding the AP between the wall and the screws.
3.2 Wiring
7. You should separate input wiring from output wiring
ATTENTION
1. Be sure to disconnect the power cord before installing and/or wiring your
switches.
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 a wire to determine
which wires should be kept separate. The rule of thumb is that wiring
sharing similar electrical characteristics can be bundled together
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.

8. It is advised to label the wiring to all devices in the system
3.2.1 Grounding
Grounding and wire routing help limit the effects of noise due to electromagnetic interference
(EMI). Run the ground connection from the ground screw on the power connector to the
grounding surface prior to connecting devices.
3.2.2 Relay Output
The device uses a M12 A-coded 5-pin male connector on the front panel for relay output. The
relay contacts will detect user-configured events and form an open circuit when an event is
triggered.
3.2.3 Power Input
The switch provides two sets of power supply on a M23 5-pin female connector to enable dual
power inputs.
Step 1: Insert a power cable to the power connector on the device.
Step 2: Rotate the outer ring of the cable connector until a snug fit is achieved. Make sure
the connection is tight.
3.3 Cables
3.3.1 Ethernet Connection
The series provide Ethernet ports in M12 connectors. According to the link type, the switch
uses CAT 3, 4, 5,5e UTP cables to connect to any other network devices (PCs, servers,
switches, routers, or hubs). Please refer to the following table for cable specifications.

3.3.2 Console Port
3.3.3 O-Ring/O-Chain
O-RING
You can connect three or more switches to form a ring topology to gain network redundancy
capabilities through the following steps.
1. Connect each switch to form a daisy chain using an Ethernet cable.
2. Set one of the connected switches to be the master and make sure the port setting of each
connected switch on the management page corresponds to the physical ports connected. For
infomration about the port setting, please refer to 4.1.2 Configurations.
3. Connect the last switch to the first switch to form a ring topology.
Coupling Ring
If you already have two O-Ring topologies and would like to connect the rings, you can form
them into a couping ring. All you need to do is select two switches from each ring to be
connected, for example, switch A and B from Ring 1 and switch C and D from ring 2. Decide
which port on each switch to be used as the coupling port and then link them together, for
example, port 1 of switch A to port 2 of switch C and port 1 of switch B to port 2 of switch D.
Then, enable Coupling Ring option by checking the checkbox on the management page and
select the coupling ring in correspondance to the connected port. For more inforamtion on port

setting, please refer to 4.1.2 Configurations. Once the setting is completed, one of the
connections will act as the main path while the other will act as the backup path.
Dual Homing
If you want to connect your ring topology to a RSTP network environment, you can use dual
homing. Choose two switches (Switch A & B) from the ring for connecting to the switches in the
RSTP network (core switches). The connection of one of the switches (Switch A or B) will act
as the primary path, while the other will act as the backup path that is activated when the
primary path connection fails.

O-Chain
When connecting multiple O-Rings to meet your expansion demand, you can create an
O-Chain topology through the following steps.
1. Select two switches from the chain (Switch A & B) that you want to connect to the O-Ring
and connect them to the switches in the ring (Switch C & D).
2. In correspondence to the port connected to the ring, configure an edge port for both of the
connected switches in the chain by checking the box in the management page (see 4.1.2
Configurations).
3. Once the setting is completed, one of the connections will act as the main path, and the
ohter as the back up path.

Redundancy
Redundancy for minimized system downtime is one of the most important concerns for
industrial networking devices. Hence, ORing has developed proprietary redundancy
technologies including O-Ring and Open-Ring featuring faster recovery time than existing
redundancy technologies widely used in commercial applications, such as STP, RSTP, and
MSTP. ORing’s proprietary redundancy technologies not only support different networking
topologies, but also assure the reliability of the network.
4.1 O-Ring
4.1.1 Introduction
O-Ring is ORing's proprietary redundant ring technology, with recovery time of less than 30
milliseconds (in full-duplex Gigabit operation) or 10 milliseconds (in full-duplex Fast Ethernet
operation) and up to 250 nodes. The ring protocols identify one switch as the master of the
network, and then automatically block packets from traveling through any of the network’s
redundant loops. In the event that one branch of the ring gets disconnected from the rest of the
network, the protocol automatically readjusts the ring so that the part of the network that was
disconnected can reestablish contact with the rest of the network. The O-Ring redundant ring
technology can protect mission-critical applications from network interruptions or temporary
malfunction with its fast recover technology.
4.1.2 Configurations
O-Ring supports three ring topologies: Ring Master, Coupling Ring, and Dual Homing. You
can configure the settings in the interface below.

Enable Ring
Master
Only one ring master is allowed in a ring. However, if more than one
switches are set to enable Ring Master, the switch with the lowest
MAC address will be the active ring master and the others will be
backup masters.
1st Ring Port
The primary port when the switch is ring master
2nd Ring Port
The backup port when the switch is ring master
Enable Coupling
Ring
Check to enable Coupling Ring.Coupling Ring can divide a big
ring into two smaller rings to avoid network topology changes
affecting all switches. It is a good method for connecting two rings.
Couple Port
Ports for connecting multiple rings. A coupling ring needs four
switches to build an active and a backup link.
Links formed by the coupling ports will run in active/backup mode.
Enable Dual
Homing
Check to enable Dual Homing. When Dual Homing is enabled, the
ring will be connected to normal switches through two RSTP links
(ex: backbone Switch). The two links work in active/backup mode,
and connect each ring to the normal switches in RSTP mode.
Apply
Click to activate the configurations.
Note: due to heavy loading, setting one switch as ring master and coupling ring at the same
time is not recommended.
