2400m. The MC250-4T/1CXT (BNC) coax performance is up to 100/65Mbps for asymmetric data rate within 200m and 31/4Mbps for asymmetric data rate at 2.4km. The IFS MC250-4T/1CXT Industrial Ethernet Converter is engineered in a slim metal enclosure that conforms to IP30 standards for deployment in demanding industrial environments. The IFS MC250-4T/1CXT provides a lower cost replacement and smooth migration for existing Long Reach Ethernet (LRE) networks.
Key Features The MC250-4T/1CXT provides the following key features: • Cost-effective VDSL2 Master / Slave bridge solution • -40º to 75º Degree C operating temperature • Redundant Power Design: 12~48V DC, redundant power with polarity reverse protect function • IP-30 metal case • One box design, Master / Slave selectable via DIP Switch • Defines Asymmetric (Band Plan 998) and Symmetric band plans for the transmission of Upstream and Downstream signals • Complies with IEEE 802.3, IEEE 802.
Hardware Overview The MC250-4T/1CXT provides 4 10/100 Mbps RJ-45, 1 RJ-11 and 1 BNC port for network line connection. The 4 RJ-45 ports will distinguish the speed of incoming connection automatically. This section describes the hardware features of the MC2504T/1CXT. For easier control of the MC250-4T/1CXT, it's recommended to get familiar with the LED indicators and port characteristics. Front panel illustrations in this chapter display the units LED indicators.

distance of connectivity. The following is a summary table of transmission settings, bandwidth and distance extensibility tested for AWG 24 (0.5mm) twisted-pair without noise and cross talk. DIP-1 DIP-2 DIP-3 DIP-4 Mode Channel Band Plan SNR OFF Master Interleave Symm 9dB ON (default) Slave Fast Asymm 6dB Master / Slave • Master (Central Office) – in Master device mode, usually the Master device will be located at the data center of the ISP or enterprise to link to the backbone.
• Interleaved mode provides impulse noises protection with a duration of less than 250 µs. Interleaved mode has a maximum end to end latency of 10m sec. Band Plan • User can switch the Band Plan to either Symmetric or Asymmetric based on the application. Symmetric band plan provides better upstream performance while Asymmetric band plan provides a better downstream performance.
Figure 2: Top Panel Installation Installing the MC250-4T/1CXT The MC250-4T/1CXT does not require any software configuration. Users can immediately use any feature of this product simply by attaching the cables and power plug. There is some key limitation on the MC250-4T/1CXT. Please check the following items: MC250-4T/1CXT: The device is used for Point-to-Point connection only (Master device to Slave device) and is equipped with one RJ-11 and one BNC connectors for VDSL2 port for network link connection.
MC250-4T/1CXT Application Connection Two sets of the MC250-4T/1CXTs could be used to link two local Area networks that are located in different locations. Through a normal telephone line or coaxial cable, 100/55Mbps (RJ-11) or 100/65Mbps (BNC) asymmetric backbone, can be setup with one media converter in Master (CO) mode and the other in Slave (CPE) mode.

Tighten the wire-clamp screws to prevent the wires from disconnecting. 1 - 2 Power 1 + 3 4 5 Fault 6 Power 2 - + Wiring the Fault Alarm Contact The fault alarm contacts are in the middle of the terminal block connector as the picture shows below. Inserting the wires, the MC250-4T/1CXT will detect the fault status of the power failure and then forms an open circuit. The following illustration shows an application example for wiring the fault alarm contacts.
1 2 3 4 5 6 Insert the wires into the fault alarm contacts Note: The wire gauge for the terminal block should be in the range between 12 ~ 24 AWG. The alarm relay circuit accepts up to 30V, max. 3A currents. Mounting Installation This section describes how to mount the MC250-4T/1CXT and make connections to it. Please read the following sections and perform the procedures in the order presented.
Mounting to a DIN-Rail The DIN-Rail kit comes assembled on the MC250-4T/1CXT out of the box. Please refer to following figures to hang the MC250-4T/1CXT on a DIN-Rail. 1. Lightly press the bottom of the DIN-Rail connector mount into the track.
2. Check that the DIN-Rail connector mount is tightly mounted on the track. 3. Please refer to following procedures to remove the MC2504T/1CXT from the track. 4. Lightly press the bottom of DIN-Rail connector mount to remove it from the track. Mounting to a Wall To install the MC250-4T/1CXT on the wall, please follows the instructions described below. 1. Loosen the screws to remove the DIN Rail from the Media Converter.
2. Place the wall mount plate on the rear panel of the MC2504T/1CXT. 3. Assemble the wall mount plate on the MC250-4T/1CXT. 4. Use the hook holes at the corners of the wall mount plate to hang the MC250-4T/1CXT on the wall.
Troubleshooting SYMPTOM: VDSL LNK LED does not light after wire is connected to the VDSL port. CHECKPOINT: • Verify that the length of the wire connected between two MC250-4T/1CXT is not more than 2.4km. Please also try to adjust the DIP switch of MC250-4T/1CXT to other SNR mode. • Please note you must use one MC250-4T/1CXT with Master mode and the other MC250-4T/1CXT with Slave mode. SYMPTOM: TP LED does not illuminate after the cable is connected to the port.
FAQs Q1: What is the voltage and current rating to power MC2504T/1CXT media converter? A1: 12 ~ 48V DC Q2: What is VDSL2? A2: VDSL2 (Very High-Bit-Rate Digital Subscriber Line 2), G.993.2 is the newest and most advanced standard of xDSL broadband wire line communications.
relative to background noise. The ratio is usually measured in decibels (dB). In digital communications, the SNR will probably cause a reduction in data speed because of frequent errors that require the source (transmitting) computer or terminal to resend some packets of data. SNR measures the quality of a transmission channel over a network channel. The greater the ratio, the easier it is to identify and subsequently isolate and eliminate the source of noise.
