ICS-105A RS-232/422/485 to 100Base-FX (SFP) Fibre Ethernet Media Converter 

Cost-effective Solution for RS-232 / RS-422 / RS-485 to Ethernet Application

PLANET ICS-105A Media Converter / Device Server can convert Serial RS-232 / RS-422 / RS-485 communication interface over Fast Ethernet networking. The ICS-105A has an SFP Slot for 100Base Mini-GBIC Fibre SFP Modules (LC type connectors) and can operate over single-mode/multi-mode Fibre depending on the SFP module selected for the customers needs. Ethernet signal allows the two types of segments to connect easily, efficiently and inexpensively. The ICS-105A converter can be used as a stand-alone unit or as a slide-in module to PLANET Media Converter Chassis (MC-700, MC-1500 and MC-1500R). It greatly saves time and expense for users and SIs without the need of replacing the existing serial equipment and software system.


Extending Distance

The ICS-105A extends the distance of deploying serial equipment and hosts. The selectable fiber-optic wires on the basis of distance are provided. Therefore, this product will perfectly satisfy the diverse demands while providing reliable and efficient network solutions based on the distance and budgets of installation.

Remote Manageable 
The ICS-105A enables the serial equipment to be connected via IP-based transmission. It also makes them able to connect to a TCP / IP networking immediately. The ICS-105A Web Smart media converter provides management through Web Interface. It supports application mode and serial operation mode, connecting alarm, IP address, etc. It helps the network administrators to reduce the amount of valuable time spending on detecting and locating network problems; otherwise, it requires visual inspection of cabling and equipment. For large networking environment, multiple connection options are available with the ICS-105A as well.

Access Control System – Traditional Installation

Most of the enterprises and governments use access control plate and Mifare or RFID to authorize entrance identity. With traditional deployment, access control machines use the RS-232 or RS-485 serial interface and cables connecting to login server. With connection with the ICS-105A Serial over Fast Ethernet Converter, the access control machine is able to be extended over longer distances via fiber optical interface. The distance can be up to 20km in a local range. The ICS-105A can also be linked to an XDSL router to get the Internet access capability; then the access control can be set and monitored over the Internet.

Process Control

The PLC (Programmable Logical Control) is required to monitor, configure and manage the Robot conveyer including other machines in the manufacturing process. The ICS-105A can be set to TCP server mode and connect with the PLC. Therefore, the administrator can remotely configure and set command settings through Fast Ethernet intranet to control the PLC, the administrators and workstations. There is no need for the administrators to be always by the side of the I/O machine.

RTU Data Collect – UDP Mode

The RTU (Remote Terminal Unit) may be applied to collect and monitor the data of waves, signal and power utilization. Connecting the RTU with the ICS-105A in UDP mode, the data can be sent over Fast Ethernet to local server or over Internet to remote server automatically.

Surveillance Motion Control – Pair Connection Mode

Using pair connection along with the fiber optic patch cord, the ICS-10x extends the remote central surveillance monitoring with the control keyboard/joystick via RS-232 / RS-422 / RS-485 interfaces.
