Your iOLab system is composed of one or two Remotes, a Dongle, and a computer running the iOLab application. The dongle communicates with the Remote(s) using a 2.4 GHz wireless link employing on a light-weight dedicated protocol, and the computer application communicates with the Dongle using a simple Virtual Com Port (RS232) serial protocol. The documents linked below describe this communication and the commands and functions understood by the system. You don't need the iOLab application to communicate with the DOngle and the Remote; as long as the virtual com port driver is enabled on your computer and have this documentation handy, you can talk to the devices using a simple terminal emulator.

The connectors on top of the iOLab device, providing analog and digital I/O pins as well as power and ground, are designed to hold user-designed expansion boards. A board to give the iOLab device 9-lead ECG functionality currently exists and is documented below.
