AntiLogPro Multiple Unit Operation


AntiLogPro OEM units can log up to two RS232 data sources simultaneously. To log more than two channels at the same time, you can combine AntiLogPro units together to form one large multi-channel RS232 data logger.

Units are connected together via their Auxiliary serial ports to form a multi-unit communications bus. Each unit is configured to use the multiple unit mode using the built in menu system, and each unit is assigned a unique bus address value from 1 to a theoretical maximum of 255. With the addition of one RS232 level shifter, the whole system can be completely controlled from a single serial port terminal application on a PC.

The following example shows three units connected together to form a six channel data logger.


Using the multi-unit bus, you can switch between record and playback mode whenever you like and you can monitor progress during a recording session. Using the bus assigned address, you can extract data from individual units after a recording session and talk to each one individually by 'connecting' to their individual menu systems all down the one serial port.

Using the multiple unit mode with AntiTermPro

Our free to download and use AntiTermPro application has been designed to provide extensive support for all of our AntiLog product range. It provide a serial port terminal display (to access the unit's menu system) and a whole host of other features including data downloading, media data extraction, unit software upgrades and of course, multiple unit operation.

Simply click on the 'Multiple Unit' button on the side menu to open the multiple unit display. Once opened, you can select from a series of tabs to choose the parameters you wish to view in real time. The following example shows the result of clicking on the 'Media' tab in a system consisting of three AntiLogPro OEM units.
