The 2-channel receiver card is used with the 6 ecg lead transmitter. At the factory, each receiver board is set to a specific frequency so as not to interfere with other channels. This board provides 2 analog ecg signals for iox software. Then, by using mathematical formulas from Einthoven model, 6 standard ecg leads (LI, LII, LIII, aVF, aVL, aVR) can be displayed and analysed. 

The front panel provides the following information/alerts:

• receiver and transmitter status
• transmission error
• low battery level
• signal strength

A BNC connector on the card receives either the receiver antenna or a BNC cable (linked to the antenna network).
