SPYDER MODEL 5 ROOM CONTROLLERS − INSTALLATION GUIDE
Automatic MAC Addressing
In contrast to other controllers (e.g., WEB-8000 controllers,
whose MAC addresses must be assigned manually – done
using their two dip switches), the WEB-RxxN controller
features automatic MAC addressing.
The MAC addresses which the individual WEB-RxxN con-
trollers in the BACnet MS/TP channel assign to themselves
are not assigned in sequential order.
Rather, they assign those numbers (MAC Addr) in the range
of 1 to maxMaster currently not in use by another device in
the BACnet MS/TP channel (the MAC Addr of "0" is reserved
by default for the router / plant controller, itself).
All WEB-RxxN controllers are BACnet MS/TP masters.
Every master performs periodic polling for the possible
appearance of new masters. Each master "knows" the
identity of the "next" master (i.e., that WEB-RxxN controller
with the next-highest MAC Addr) on the BACnet MS/TP bus
and to which it must therefore pass the token. The polling
process includes a search for new masters which might
have MAC addresses lying between its own MAC address
and that of the "next" master.
The property maxMaster specifies the highest-allowable
address for master nodes. maxMaster is set to 32 by
default, thus guaranteeing that, on a BACnet MS/TP bus
with, e.g., 32 WEB-RxxN controllers, all of the other WEB-
RxxN controllers will be found. Both the property
maxMaster and the property MAC address are writeable
properties that can be changed.
NOTE: You should not attempt to program a MAC Addr
outside the range of 1 to maxMaster.

Fig. 12. Automatic MAC addressing
In the scenario depicted in Fig.15, some of the controllers
in the BACnet MS/TP channel do not feature automatic
MAC addressing; rather, their MAC addresses were
assigned manually (e.g., using their two dip switches). Thus,
when a new WEB-RxxN is added to the channel, when its
automatic MAC addressing function is triggered, it will
assign itself an available (i.e., unoccupied) MAC address.
During the automatic MAC addressing process, LED
behavior #7 (see Table 7) is displayed.

Service Button

The Service Button is used to trigger dedicated events.
It is important to distinguish different controller behaviors
which are elicited depending upon whether the Service
Button is pressed when the controller is powering up or
when it is in normal operation. See the following sub-
sections.
Pressing Service Button during Power-Up
During controller power-up, pressing the Service Button
until LED behavior #3 (see Table 8) is displayed will reset
the controller to its factory settings, which are as follows:
▪ The application is cleared from the controller.
▪ The MAC address will be set to 0xFF, meaning that the
