INTRODUCTION

Description of Devices

The W7761A, Excel 10 Remote Input/Output device, provides auxiliary inputs and outputs for use with an Excel 10 Zone
Manager and Excel 10 controllers over the Echelon
tool. The W7761A device uses Echelon
transceiver (FTT) for greater network installation flexibility. The Excel 10 RIO device can be combined with the Excel 10 Zone
Manager (FTT), other Excel Controllers, and the Excel Building Supervisor, to provide a complete and low cost control solution
for small to large commercial buildings.
The Q7750A Excel 10 Zone Manager is a communications interface that allows devices on the E-Bus network to communicate
with devices on the standard EXCEL 5000® System C-Bus. Fig. 1 shows an overview of a typical system layout. The Q7750A
also provides some control and monitoring functions.
