Hey there fellow tinkerers.

Currently I need to come up with a solution so that I can run my lighting controller from a remote location. The Lighting controller runs off a RS232 interface;- thing is where the lights are mounted, I can not see the controller and vice -versa. I'm trying to come up with a solution so that I can run my laptop to a remote location and send RS232 commands from my remote location to the Lighting controller. That way I can see what effects my lighting shows have in real time Smile

The Lighting Instructions I give are over RS232 (standard 8N1) @ 19.2k.
The Packets I will be sending are few and far between (basic trigger patterns to trigger shows stored on the lighting controller itself). The Packet length is 10bytes.

What I am looking for is the best (most reliable and most cost effective solution) to doing this control- note it has to be wireless! Note - I am looking for a premade professional solution - not a Kit. Something as plug and play as possible.

I'm guessing a RS232 to RF module at each end may be the best solution, but I am open to other suggestions. (to be honest I don't know the 1st thing about stuff like 802.11b etc so any suggestions outside the circle would be most welcome.)

Also other peoples experiences with RS232 run lengths would be appreciated (ie how far)- note that this link is not permanent and is only for short term test
purposes. This particular RS232 link uses only RX,TX and GND connections.

Below is a picture of the current configuration.

Look foward to some stimulating suggestions.

thx,

You could think of Bluetooth. There are e.g. Bluetooth modules of Bluegiga. They can be used in a transparant RS-232 link. They can reach 100m but when using different antennas it will probably be possible to get better results.

Check out

I HAVE NOT used them, don’t know about price (probably high), quality etc.
I think Lynx also has similar products.

Hi,

Check out the WiPort from Lantronix.

Its a serial to WiFi gateway. Really easy to use.

Dave.

Spark Fun Electronics has some items that look interesting. See this link. The RF-KLP916 T/R pair for US$ 24.95 at the bottom of the page has a range of 300 feet and is capable of 200Kbps.

Note: I have no experience with any of these items. Has anybody played with any of them?
