The 4-channel receiver board is used with the 4-channel ecg transmitter (6 standard ecg leads + one chest lead + activity).

At the factory, each receiver board is set to a specific frequency so as not to interfere with other channels. This board provides 4 analog signals (3 ecg signals and 1 activity signal) for iox2 software. Then, by using mathematical formulas based on the Einthoven model, 6 standard ecg leads (LI, LII, LIII, aVF, aVL, aVR), one chest lead and activity can be displayed and analysed. 

• 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).
