SECTION 4 - SC-AP GATEWAY
To Change the Device Instance
The SC-EQ automatically creates the Device Instance
as 5000 plus the MAC Address switch setting. For ex-
ample, if the MAC address DIP switches are set to a
value of 6, the Device Instance is 5006. Some custom-
ers require the Device Instance to be something other
than the automatically generated 5000 series address.
The SC-AP can be used to change the Device Instance
to the customer desired address. Connect the SC-AP
to the SC-EQ and log on to the SC-AP using a WiFi
interface either from a Smartphone, a Laptop or Tablet
PC. Refer to
SC-AP Installation (Lit 24-10737-75)
and
SC-AP Quick Start (Lit 24-10737-87 ) for more infor-
mation on the SC-AP.
Note that any MAP 4.0 device may be used to connect
to the SC-EQ to change the Device Instance and to also
look at the communication port status. It is not able to
communicate with the Cloud though. When you first
click on a MAP 4.0 device, the Home page loads and
displays a "spinner" that never stops since it is looking
to connect to a Simplicity SE or a RTU controller and
can not find them. The user must just proceed to click
on a menu item on the left-hand side to view informa-
tion.
The MAP1810 device uses two MAC address of 2. So
a temporary change of the SC-EQ mac/node address 2
allows a CS port port mac/node# change as shown in
Figure 48 . The virtual MAC address is separate from
BMS. When it finishes, the address can return to 2.
1. Select the SC-EQ Device then select the SC-EQ
Data tab.

E-LINK REPLACEMENT
In BACnet autodiscovery, the E-Link transferred a list
of all possible chiller parameters to the BAS. Even
ones that did not apply. For example, if you had an
Electro-Mechanical starter, the parameters for a VSD
starter were shared by the E-Link and auto-discovered
by the BAS. The SC-EQ discovers what type of chiller
is connected and the chiller features and then exposes
only the relevant points to the BAS. If an E-Link is
replaced by an SC-EQ, the BAS shows the points that
were non relevant previously as Offline. To resolve this
you either need to delete the E-Link and re-discover
the SC-EQ or delete each of the inappropriate Offline
points.

BAS Commands
Points that are commandable show as Unreliable until
the BAS sends the setpoints.
