Trying to connect 4 Serial Devices

[rayw751]

Hi All,

I am trying to connect 4 serial devices to a system. I do not have enough COM ports on my PC and need some device that will allow me to overcome this limitation.
Does any one know of a device which will help me connect 4 serial devices together?

What is this "system"?

A PC? http://www.neutronexpress.com/mfgst...172,4,4187,0&gclid=COaztIO4paECFRZ5gwodsg_bCw or google serial multiplexer

A AB PLC with ethernet? http://www.prosoft-technology.com/content/view/full/14578

if you have 4 devices that are communicating to one pc then you can use a black box splitter.

I recommend the I-7188E4 series module from ICP DAS USA, Inc.
Click the following link to find the details.
They have modules that support from 1 serial device upto 8 serial devices.

It essential acts like a serial port extender.

USB to serial converter. If you don't have 4 USB ports you could use a USB hub.

Some really good advice here but we dont actually know what the "system" is so its all conjecture !
