Console Management

When there is a problem in a computer system, a majority of the system managers try to access to the device via a console port. Most of the IT equipment are equipped with a system console port, and console connection is a common method for managing the equipment.

The console port is available even though there is a network or system failures. Also, it can be directly connected through a serial port for controlling and monitoring the system. However, because the console port is based on a RS232 communication, it is limited to the communication distance.

Sollae Systems’ console servers, CSE-T16 and CSE-T32, can help you to connect your system console to a network. Therefore, if a network connection is enabled, you can escape from the constraint of distance communication.Console Management

Remote Carbon Dioxide Measuring System

Sollae Systems’ serial to Ethernet device servers can be applied with a remote carbon dioxide measuring system.

Carbon dioxide meters measure the concentration of carbon dioxide to maintain clean air for the quality of crops in a greenhouse, a big-sized refrigerator or in a cargo ship.

Sollae Systems’ serial to Ethernet device servers give a network function to gather the meter’s data at a remote site for real-time monitoring.Remote Carbon Dioxide System (3)


Output Port Pulse Control With User Webpage Javascript

Sollae Systems’ remote I/O controllers, except for EZI-10, enable users to upload their own webpages to monitor input ports and control output ports.

Basically you can control some special performances as well as basic ones on the webpages with Javascript. So, in this article, we will go through how to enable pulse control of output ports using Javascript.

Pulse output is generally to keep changing states – high or low- on a regular basis. But this time we will write a code to make it stayed for specified time as it set time and back to the original state.

For this demonstration, we will use an 1-port remote I/O controller,  CIE-H12 which comes preloaded with the following source code.

Let’s add Javascript above #head# as follows.

Now the output port of CIE-H12 will have an output value for specific time and get back to normal as it was.

“2000″ represents 2,000ms, which means 2 seconds, so the output port will stay ON for 2 seconds and back to OFF.

The video below will show you how CIE-H12 works in real.

You can also do pulse control with a ‘P’ tag supported by firmware ver. 1.5A.
