Title : Development of Application to Control Projector Remotely

Id : 38578314

Estimated Budget : upto 700 USD

Description :

We are Germany based company looking for experienced service provider to develop an application to control projector via RS232. We want an application so video projectors can be controlled remotely with an serial (RS232) connection between the projector and a computer. This remote control should include always an “on / off” –functionally and a number of other possibilities in respect to the device (like focus control, lamp hour reading, keystone…).

We want to integrate this functionality in our desktop-based c++ Microsoft windows application. A large number of projectors should be supported, reading the serial codes / settings out of a XML-database. This database should be open for future additions.

We want service provider to develop the application in below steps.

A) Implement a MS Windows compatible c++ routine for the communication over the serial (RS 232) line between computer and video projectors. Be aware of different serial (RS232) communication methods and of checksum control. Provide us with the code as a fully compiling MS Visual Studio project and the full rights to reuse it. Also include documentation. Do not use any library that has to be licensed commercially without asking
B) Build a matching XML –Database construct to read the needed data for different projectors
(Name, model, serial commands, serial communication, possible functions)
Provide an interface to choose the projector model by a drop-box.
Implement the following functionality:
- Turn on
- Turn off
- Choose input source (if available)
- Read lamp hour (if available)
Provide us with documentation.
C) Research several projector serial codes, checksum methos and serial communication standards (Baud rate, Bit…) for the following brands and integrate them into the database
a. EPSON
b. NEC
c. Optoma
d. Infocus
e. BenQ

Our approximate budget up to 700 USD and we are ready to make 20 % as an advance payment and the rest of the amount will be paid according the progress of the work via PayPal. Interested service providers are requested to contact us as soon as possible with their profile.

Note- No calls will be entertained, Please contact via email
