Overview

The PTC-101-M12 industrial media converter is designed to provide

reliable and stable operation in harsh industrial environments. The

PTC-101-M12 converts between 10/100BaseT(X) and 100BaseFX. To

keep your industrial automation applications running continuously, the

PTC-101-M12 comes with a relay output warning alarm to help prevent

damage to your equipment.

The PTC-101-M12 has a wide operating temperature range of -40 to 85°C,

and is designed to withstand a high degree of vibration and shock. The

rugged hardware design makes the PTC-101-M12 perfect for ensuring

that your Ethernet equipment can be used with critical industrial

applications, such as in hazardous locations. The converter complies with

FCC, UL, and CE standards.

Wiring Requirements

ATTENTION

Safety First!

•

Be sure to disconnect the power cord before installing

and/or

wiring your PTC-101-M12.

•

Calculate the maximum possible current in each power wire

and common wire, and observe all electrical codes dictating

the maximum current allowable for each wire size.

•

If the current goes above the maximum ratings, the wiring

could overheat, causing serious damage to your equipment.

- 5 -

You should also pay attention to the following:

•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.

NOTE

Do not run signal or communications wiring and power wiring in

the same wire conduit. To avoid interference, wires with different

signal characteristics should be routed separately.

•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 that shares similar electrical characteristics can be

bundled together.

•Keep input wiring and output wiring separated.

•It is strongly advised that you label the wiring to all devices in the

system.

Grounding the PTC-101-M12

Grounding and wire routing help limit the effects of noise due to

electromagnetic interference (EMI). Run the ground connection from the

ground screw to the grounding surface prior to connecting devices.

ATTENTION

This product is intended to be mounted to a well

-grounded

mounting surface such as a metal panel.

Wiring the Redundant Power Inputs

The top five contacts of the 8-contact terminal block connector on the

PTC-101-M12’s top panel are used for the two DC inputs. Top and front

views of one of the terminal block connectors are shown here.

STEP 1: Insert the negative/positive DC wires

into the V

-/V+ terminals.

STEP 2:

To keep the DC wires from pulling

loose, use a small flat

-blade screwdriver to

tighten the wire

-clamp screws on the front of

the terminal block connector.

STEP 3:

Insert the plastic terminal block

connector prongs into the terminal block

receptor, which is located on the

C-101-M12’s top panel.

ATTENTION

Before connecting the PTC

-101-M12 to the DC power inputs,

make sure the voltage of the DC power source is stable.

Communication Connections

The PTC-101-M12 has one 10/100BaseT(X) Ethernet port, and one

100BaseFX (SC or ST type connector) fiber port.

10/100BaseT(X) Ethernet Port Connection

The 10/100BaseT(X) ports located on the PTC-101-M12’s front panel are

used to connect to Ethernet-enabled devices.

Pinouts for the 10/100BaseT(X) Ports

M12 (4-pin, M) to M12 (4-pin, M) Cross-Over Cable Wiring

M12 (4-pin, M) to M12 (4-pin, M) Straight-Through Cable Wiring

Auto MDI/MDI-X Connection

The Auto MDI/MDI-X function allows users to connect PTC-101-M12’s

10/100BaseTX ports to any kind of Ethernet device, without needing to

pay attention to the type of Ethernet cable being used for the connection.

This means that you can use either a straight-through cable or cross-over

cable to connect the PTC-101-M12 to Ethernet devices.

100BaseFX Ethernet Port Connection

The concept behind the SC port and cable is quite straightforward.

Suppose you are connecting devices I and II. Contrary to electrical signals,

optical signals do not require a circuit in order to transmit data.

Consequently, one of the optical lines is used to transmit data from device

I to device II, and the other optical line is used transmit data from device

II to device I, for full-duplex transmission.

All you need to remember is to connect the Tx (transmit) port of device I

to the Rx (receive) port of device II, and the Rx (receive) port of device I

to the Tx (transmit) port of device II. If you are making your own cable,

we suggest labeling the two sides of the same line with the same letter

(A-to-A and B-to-B, as shown below, or A1-to-A2 and B1-to-B2).

Redundant Power Inputs

The PTC-101-M12 has two power inputs, which can be connected

simultaneously to live DC power sources. If one power source fails, the

other live source acts as a backup, and automatically supplies all of the

PTC-101-M12’s power needs.

DIP Switch Settings

DIP No.

Function

OFF

Auto Negotiation

Enable

Disable

“ON”:

Enables the

“Auto Negotiation” function. The speed and duplex

states for each port link segment are automatically configured

using the highest performance interoperation mode.

“OFF”:

Disables the “Auto Negotiation” function. The speed and duplex

states depend on the

manual setting configuration.

Force TP Speed

100 Mbps

10 Mbps

(Only when Auto Negotiation is disabled)

“ON”:

Forces the Ethernet port to use 100 Mbps transmission.

“OFF”:

Forces the Ethernet port to use 10 Mbps transmission.

Force TP Duplex

Full Duplex

Half Duplex

(Only when Auto Negotiation is disabled)

“ON”:

Forces the Ethernet port to use Full Duplex.

“OFF”:

Forces the Ethernet port to use Half Duplex.

Link Fault Pass Through

Enable

Disable

“ON”:

Enables “Link Fault Pass Through.” The link status on the TX port

will inform the FX port of the same device and vice versa.

“OFF”:

Disables “Link Fault Pass Through.” The link status on the TX port

will not inform the FX port.

Operating Mode

Store-and-Forward

Pass Through

“ON”:

Selects

“Store-and-

Forward” mode. Begins to forward a packets

to a destination port after an entire packet is received. The latency

depends on the packet length.

“OFF”:

Selects “Pass Through” mode. Operates with the minimum

latency. Both transceivers are

interconnected via internal MIIs

and the internal switch engine and data buffer are not used.

Note:

With “Pass Through” mode enabled, the Ethernet port and fiber

port should transmit at 100 Mbps, which is equivalent to full

duplex mode.

Default DIP settings are all in the ON position.

ATTENTION

After changing the DIP switch setting, you will need to power off

and then power on the PTC-101-M12 to activate the new setting.
