Some Examples of how a Diplomat jrN might be used

Example 1 - Connecting a legacy device to a standard PC

The intellectually challanged asynchronous device might be a Programmable Logic Controller, a Cheque Printer , a Telex Converter etc. I might be almost anything that has an RS232 connector on it!

Programming an application in Visual Basic, or other language able to use the MS Winsock control, is straightforward. A TCP or UDP connection can be made easily over a LAN or WAN to a Diplomat jrN which is connected to your legacy equipment via a RS232 port. The legacy equipment can now be controlled from your desktop Wintel PC.

Using a simple application running on the PC, you can re-configure a geographically remote Diplomat jrN as well as receive status information about the legacy device.

Example 2 - Controlling several remote devices

You may wish to control several old polled asynchronous devices which have RS232 connectors but do not have network interfaces. A Diplomat jrN provides this interface by connecting to the RS232 port on one side and the LAN or WAN on the other.

The application running on the PC simply has to talk to the COM port but the Diplomat jrN broadcasts the poll messages over the IP subnet using the IP/UDP protocol.

The individual jrN's supporting each legacy device, forward the messages to them. All messages sent back from the legacy devices are returned to the COM port of the PC. The application can examine the content of the message to determine which device sent it.
