2.5 DIP Switch and Link Type
Link Type
The BNC mode allows Industrial Ethernet Extender to connect and transfer data by using BNC cable.
The RJ11 mode allows Industrial Ethernet Extender to connect and transfer data by using telephone wire
DIP Switch
The Industrial Ethernet Extender provides a selectable 4-position DIP switch. Switch them on or off to obtain the best coaxial/RJ11 cable connection over a distance.
| DIP | DIP-1 DIP | -2 DIP-3 DIP-4 | ||
| Mode Transmission Band | Profile SNR Margin | |||
| OFF CO G.INP | Asymmetric 1 | 2dB | ||
| ON (default) | CPE Interleave | Symmetric | 8dB | |

Note
By default, the 4-position switches of the DIP switch, set at the "ON" position, are operated as "CPE". For operating as "CO", please turn DIP 1 switch to the "OFF" position. Then adjust other DIP switches accordingly to fulfill different network application demands.
■ DIP-1: Mode (CO / CPE)
| CO (Central Office) | The Master device mode, usually the CO device, is located at the data center of ISP or enterprise to link to the backbone. |
| CPE(Customer Premises Equipment) | The Slave device mode, usually the CPE device, is located at branch office, home or remote side as the long reach data receiver. The CPE can be connected to the PC, IP camera or wireless access point, or other network devices. |

Note
When the Industrial Ethernet Extender operates in CPE mode, DIP switches 2, 3, and 4 are without function.
■ DIP-2: Transmission (G. INP and Interleave mode)
| G. INP | Method of protection against bursts from other devices or lines to impact your xDSL connection. |
| Interleave | Method of error correction used on xDSL connection.Interleave requires additional latency to improve resilience to burst of error. |
■ DIP-3: Band Profile (Asymmetric/Symmetric)
| Asymmetric | The asymmetric mode provides more bandwidth than the other side. This mode provides the highest bandwidth in short range. |
| Symmetric | With the G.997 band plan supported, the symmetric mode can provide almost the same rate of downstream and upstream. |
■ DIP-4: SNR (Signal Noise Ratio) Margin
When the SNR margin is selected, the system provides 12dB/8dB SNR margin for all usable loop lengths. Better channel noise protection is made with the higher SNR margin.

Please power off the Industrial Ethernet Extender before making any transmission mode adjustment.

4. Applications
The Industrial Ethernet Extender does not require any software configuration. Users can immediately use any feature of this product simply by attaching the cables and turning the power on. There are some key limitations on the Industrial Ethernet Extender. Please check the following items.
4.1 Point-to-Point Application -- LAN to LAN Connection
One set of the Industrial Ethernet Extender could be used to link two local area networks that are located in different places. Through the coaxial cable, it could set up a 200/100Mbps asymmetric backbone, but one Industrial Ethernet Extender must be Master (CO mode) and the other one is Slave (CPE mode).

- The following application is connected by Coaxial cable, you have to transfer the 2-Position DIP switch to the BNC mode. The other connection type must be transferred to RJ11 and connect by RJ11/telephone wire.
- Only one wire can be connected at a time, coaxial or RJ11.

7. Troubleshooting
SYMPTOM:
VDSL LNK LED does not light up after wire is connected to the VDSL port.
CHECKPOINT:
-
Verify the length of the coaxial cable (not more than 1.2km) connected between the two IVC-234GT units. Please also try to adjust the DIP switch of the IVC-234GT to the other SNR mode.
-
Please note you must use one IVC-234GT in CO mode and the other IVC-234GT in CPE mode to make connection to each other work.
SYMPTOM:
TP LED does not light up after cable is connected to the port.
CHECKPOINT:
- Verify you are using the Cat.5e or better cable with RJ45 connector to connect to the port.
- If your device (like LAN card) supports auto-negotiation, please try to manually set at a fixed speed of your device to solve this issue.
- The IVC-234GT and the connected device's power are on or not.
- The port's cable is firmly seated in its connectors in the switch and in the associated device.
- The connecting cable is good and with the correct type.
- The connecting device, including any network adapter, is functional.
8. FAQs
Q1: What is VDSL2?
A1: 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.
Designed to support the wide deployment of Triple Play services such as voice, data, high definition television (HDTV) and interactive gaming, VDSL2 enables operators and carrier to gradually, flexibly, and cost efficiently upgrade the existing xDSL-infrastructure.
Q2: What is SNR and what's the effect?
A2: In analog and digital communications, Signal-to-Noise Ratio, often written as SNR, is a measure of signal strength 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.
Generally speaking, the higher SNR value gets, the better the line quality gets, but performance is lower.
Q3: What is the best distance for IVC-234GT?
A3: In order to guarantee the stability and better quality of network, we suggest the distance should not exceed 1.2 kilometers.
