NXC-VAI4 module

VA and VAI4

There is no VAI4 module, you will need to define the device and write associated code in the custom.axi file. Programming the VA14 is fairly simple, for more information and programming help, refer to the doc at this link:
http://amx.com//techdocs/0602313.pdf

VAI4 example code

Open the workspace in NetLinx Studio and then open custom.axi.
Under DEFINE_DEVICE
dvLIGHT = 5002:1:0

In the DEFINE_START section you should set the limit so the voltage does not go over 10VDC
SEND_COMMAND dvLIGHT 'P1X10V' (* Sets the maximum output level for I/O #1 to 10 Volts *)

In DEFINE_EVENT you may use SEND_COMMAND, Levels, or channels to control the lights.
SEND_COMMAND dvLIGHT, 'P1L50%' // ramps I/O 1 from its current value to 50% (mid voltage level) at the "CURRENT I/O 1 RAMP RATE".
'P2L255T30' ramps I/O 2 to maximum voltage level in 3 seconds.

CHANNEL examples:
ON[dvLIGHT,1]
Channel State Function

---

1 ON While channel 1 is ON the voltage on I/O 1 (Output 1)

will ramp up (increase) at the "CURRENT I/O 1 RAMP UP

RATE" . The voltage ramp stops if the maximum is

reached.

OFF Stop voltage ramping on I/O 1 at current value.

All of these examples are available in AMX PI (Product Information)
