WIRING
Airow Station
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, or Paragon Airow Measurement Digital
Transmitter to the VCCX2 Control System. Wire the airflow
Measurement Digital Transmitter to the adapter board as shown in
Figure 12, this page.
Up to four EBTRON, GreenTrol, or Paragon MicroTransEQ Airow
Measurement Digital Transmitters can be attached to each Adapter
Board. Only one Paragon Multi-Trans Smart Ecosystem (MTSE)
can be attached.
Only the EBTRON GTC116 or HTN104 series, GreenTrol 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 airow station options.
The Airow Station’s baud rate needs to be set to 19,200 in order
to communicate with the VCCX2 Controller (excludes Paragon
MTSE).
When conguring the GTC116 or HTN104 Series, be sure to set
the parity to “NO PARITY, 1 STOP BIT.”
Paragon MTSE must be congured for MODBUS communication
with baud rate set to 57,600 and its MODBUS ID set to “9”.
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.
