BenQ Projector Binding

This binding is designed to interface with BenQ projectors that have an RS232 interface on them that accepts the commands documented by BenQ in [1].

Status

This binding is current in Beta state with the following commands implemented:

Command	Query	Set	Comments
Power	Y	Y
Mute	Y	Y
Volume	Y	Y
Source	Y	Y	Can be returned as either a string or number
Lamp Time	Y	N

Tested Devices:

• BenQ W1080

Transports

The binding has currently been developed using a TCP/IP to RS232 converter. A direct RS232 interface needs to be implemented.

Known working converter is the USR-TCP232-2.

Binding Configuration

############################# BenqProjector Binding  ########################################

# device interface
benqprojector:deviceId=<hostname>:<port number>

# set interval to refresh status from projector
benqprojector:refresh=15000

# following is default, non-network mode is not implemented
#benqprojector:networkMode=true

Item Configuration

Example of Item bindings:

Switch gf_lounge_multimedia_projectorPower "Projector Power" (gf_lounge, gf_multimedia) {benqprojector="power"}
Switch gf_lounge_multimedia_projectorMute "Projector Mute" (gf_lounge, gf_multimedia) {benqprojector="mute"}
Number gf_lounge_multimedia_projectorVol "Projector Volume [%d]" (gf_lounge, gf_multimedia) {benqprojector="volume", autoupdate="false"}
Number gf_lounge_multimedia_projectorSourceNum "Projector Source [MAP(ProjSourceNum.map):%s]" (gf_lounge, gf_multimedia) {benqprojector="source_number"}
String gf_lounge_multimedia_projectorSourceString "Projector Source [%s]" (gf_lounge, gf_multimedia) {benqprojector="source_string"}
Number gf_lounge_multimedia_projectorLamp "Projector Lamp [%d hours]" (gf_lounge, gf_multimedia) {benqprojector="lamp_hours"}

Example source mapping:

0=Computer
1=Computer 2
2=Component
3=DVI-A
4=DVI-D
5=Sky TV (HDMI)
6=Chromecast (HDMI2)
7=Composite
8=S-Video
9=Network
10=USB Display
11=USB Reader
-=Unknown
undefined=Unknown

Example sitemap:

	Frame label="Media" {
		Switch item=gf_lounge_multimedia_projectorPower
	}
			
	Frame label="Projector" visibility=[gf_lounge_multimedia_projectorPower==ON] {
		Selection item=gf_lounge_multimedia_projectorSourceNum label="Projector Source" mappings=[5="Sky TV", 6="Chromecast"]  visibility=[gf_lounge_multimedia_projectorPower==ON]
		Switch item=gf_lounge_multimedia_projectorMute visibility=[gf_lounge_multimedia_projectorPower==ON]
		Setpoint item=gf_lounge_multimedia_projectorVol step=1 minValue=0 maxValue=10 visibility=[gf_lounge_multimedia_projectorPower==ON]
