PT-Link II N2-3
®
Technical Guide
The OE368-23N-N2-3, PT-Link II N2-3
®
provides bi-directional com-
munication between your N2
®
MS/TP
protocol network and up to four*
of any of the following types of Orion controllers—VCM-X, SA, VCM,
MUA II, or VAV/CAV:
VCM-X Controller (SS1026, SS1032, SS1033, Y200920)
SA Controller (Y200921)
VCM Controller (SS1016, Y200409, Y200616, Y200822)
**VAV/CAV Controller (SS1003, Y200301) and
MUA II Controller (SS1004, Y200405)
To determine what controller you have, you must look at the label lo-
cated on the controller EPROM. If the controller label does not match
any of the SS or Y numbers listed above, your controller will not work
with the PT-Link II N2
®
.
*NOTE:
The PT-Link II N2
®
device can be used to connect to only
four Orion controllers. If more than four Orion control-
lers are present in a system, you will need one or more
additional PT-Link II N2
®
devices for integration with
an N2
®
protocol network.

NOTE:
Documentation is available for MUA II/VAV/CAV on
our Orion Controls website: www.orioncontrols.com.
Data Sharing
The PT-Link II N2
®
interface provides the following data sharing
capabilities:
•
Provides values from points on the Orion side of the
gateway to N2
®
devices as if the values were
originating from N2
®
objects.
•
Allows N2
®
devices to modify point values on the
Orion controller side of the PT-Link II N2
®
by using
standard
N2
®
write services.
Scheduling
•
Ability to allow N2
®
devices to send Schedule events
to the Orion controller side of the gateway by using
standard
N2
®
services.
