Acuity Controls nLight ECLYPSE User Manual

For the ECLYPSE Controller, set the
Max Info Frames
to 20 in the screen shown in BACnet Settings of the Network MS/TP
Ports as this is a device that will make more requests for service from other devices on the network. In general, according
to the way a device is programmed, the
Max Info Frames
may have to be set to a higher value than for other devices. For
example, when Roof Top Unit Controllers are used with VAV controllers that use
specific code, they should also have their
Max Info Frames set to a higher value such as 5, as Roof Top Unit Controllers will poll many VAV controllers for informa-
tion.
To set the
Max Master
and
Max Info Frames
for BACnet MS/TP devices (for example, a BACnet controller), use a Supervi-
sor to do so.
Default Device Instance Number Numbering System for nLight ECLYPSE Controllers
By default, nLight ECLYPSE controllers automatically self-assign a Device Instance number generated from the unique
MAC Address assigned to the controller during installation. The Device Instance number is calculated as follows:
Device Instance number = 364 X 1000 + MAC Address
Where 364 is the nLight ECLYPSE controller’s unique BACnet Manufacturer ID.
This Numbering system is sufficient for a BACnet network that has only one nLight ECLYPSE Controller. For larger BAC-
net networks that have more than one controller (to form a BACnet intranetwork), set the MAC Addresses, Device Instance
Numbers and Network Numbers according to the numbering scheme below.
