VCCX2 Controller Technical Guide
EBTRON

, and Paragon
Airflow Measurement Digital
Transmitters
The E-BUS Adapter Board attaches to the VCCX2 Controller
with an E-BUS cable. The Adapter Board is used for connecting
the EBTRON
®
, GreenTrol
TM
, or Paragon Airflow Measurement
Digital Transmitter to the VCCX2 Control System. You must
wire the Airflow Measurement Digital Transmitter to the Adapter
Board as shown in
Figure 31, this page
.
Up to four EBTRON
®
, GreenTrol
TM
, or Paragon Airflow
Measurement Digital Transmitters can be attached to each
Adapter Board.
If using multiple E-BUS Sensors or Modules, the E-BUS Hub
(ASM01635 or G033970) or E-BUS Adapter Board (ASM01878)
may be required.
WARNING:
Observe Polarity! All boards must be wired
with GND-to-GND and 24 VAC-to-24
VAC. Failure to observe polarity will result
in damage to one or more of the boards.

NOTE:
Only the EBTRON® GTC116 or HTN104 series,
GreenTrolTM GA-200-N Module (with GF series
Airflow Station), or Paragon MicroTransEQ series
of MODBUS RTU transmitters are compatible
with the VCCX2 Controller. No other series of
transmitters will work for this application. Contact
AAON Controls for information on other airflow
station options.
NOTE:
The Airflow Station’s baud rate needs to be set to
19,200 in order to communicate with the VCCX2
Controller.
NOTE:
When configuring the GTC116 or HTN104 Series,
be sure to set the Parity to “NO PARITY, 1 STOP
BIT.”
