The Planet ICS-115A Serial Device Server (Serial over Fibre / Ethernet)  is specially designed to convert RS232, RS422 or RS485 serial communication to Fast Ethernet networking via Fibre SFP Modules to extend the network distance efficiently and inexpensively. 

There are 100BASE-FX single-mode (MFB-F20) /Multi-Mode (MFB-FX) SFP Modules available to work within the ICS-115A and its operating temperature ranges from -10 to 60 degrees C for your network needs. The ICS-115A is a time-saving and cost-effective solution for users and system integrators to quickly transform their serial devices into the Ethernet network with no need of replacing the existing serial devices and software system.

Extending Distance

The ICS-115A is able to extend the distance of deploying serial equipment and hosts. The selectable fibre-optic cables 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 Management 

As the ICS-115A provides an easy serial-to-Ethernet connectivity and connection to a TCP/IP network, the remote network system can thus be managed efficiently via its Web, telnet and VCOM management interfaces. It supports both application and serial operation modes for alarm or IP address connection, which saves the network administrator’s time in detecting and locating network problems without visual inspection of the cabling and devices.  Multiple connection options are available for large networking environment as well.

Easy Chassis Installation

The ICS-115A can be used as a stand-alone unit or a slide-in module to PLANET Media Converter Chassis (MC-700 and MC-1500/MC-1500R chassis). The media chassis can assist in providing DC power to the ICS-115A and can be DIN-rail or wall mounted for efficient use of cabinet space, without the need of replacing the existing serial equipment and software system.

Access Control System – Traditional System Application

Most of the enterprises and government use access control plate and Mifare or RFID to authorize entrance identity. Traditionally, the access control machines use RS232 or RS485 serial interface with their cables connecting to login server. By applying the ICS-115A Serial Device Server, the access control machine is able to extend the network over longer distances via Ethernet interfaces. In addition, the ICS-115A can be linked to an xDSL router to get the internet access capability so that the access control can be set and monitored over the internet.

Process Control

To monitor, configure and manage the robotic conveyer including other production machines, PLC (programmable logical control) is required to drive the above manufacturing process. The ICS-115A can be set to the TCP server mode and connected to the PLC.  Thus, the administrator can configure and set command settings through Fast Ethernet intranet to remotely control the PLC, without having to stand by the I/O machine.

RTU Data Collect – UDP Mode

Connect with RTU (remote terminal unit) to collect and monitor the data of waves, signal and power utilization. The ICS-115A can be used to set up UDP mode and send data over Fast Ethernet to local server or over Internet to remote server automatically.

Surveillance Motion Control – Pair Connection Mode

Using pair connection mode via the fiber optic patch cord, the ICS-115A can extend the distance of the deployed devices via RS232, RS422 and RS485 interfaces, making the remote management of these devices from the monitoring center easier and efficient.
