Projector Controller w/ Built-n VGA Splitter

Description

The Model HR-3P is a programmable serial device with 3 video inputs VGA, Composite
Video (CV) and S-Video (Y/C). The VGA input supports all PC resolutions to 1600x1200 and
the TV video inputs are NTSC, PAL, and SECAM compliant. The unit has a VGA splitter with
2 VGA outputs, but the CV and S-Video have only one output each (pass through). The
HR-3P can detect video on any of the inputs and issue preprogrammed serial commands
via its RS-232 port. It also features 1 discrete (digital or contact closure) input and 1
discrete output. The discrete input can be used to issue commands on its high-to-low, and
low-to-high transitions. The unit also keeps track of ON/OFF state of the projector and
outputs a TTL (hi/lo digital) signal on its discrete output line for controlling other external
devices such as lowering and raising a screen. The HR-3P is an ideal tool for the
automation of a projector.

The commands sent to the projector can be any ASCII (or non-ASCII) data with
programmable delays embedded in the string.

Hall Research Technologies, Inc. provides a powerful Windows™ based application that is
used to create the data files and upload it to the HR-3P.

Features

1. Compact, Rugged, Reliable, and Economical

2. High Resolution VGA Distribution amp can drive cables to 150 feet on outputs

3. Wide bandwidth supports resolutions to 1600x1200 at any refresh rate

4. Up to 8 user-programmable Command Strings

5. Allows multiple instances of user-defined delays within each string

6. Detects video on any input , or no video at all

7. Digital (discrete) input and output on screw terminals

8. Intuitive Operation

9. Comes with Windows™ software for programming

10. Made in USA

How to Obtain the Windows® Programming Software

The GUI (Graphical User Interface) needed to program the HR-1P can be downloaded at:

Setup to Program HR-3P

1. Connect the provided power supply to the power port on the back right side of

the device.

2.

Connect a crossover serial cable (provided) from a PC to the HR-3P.

3.

Install the HR-3P Programmer software on the PC.

Setup to Use HR-3P

1. Connect the provided power supply to the power port on the back right side of
the device.

2. Attach any VGA, Composite, and/or S-Video signals as necessary to the
appropriate input jacks on the back of the device.

3. Connect the output from the video signals to appropriate video display devices.

4. Connect the discrete inputs to an appropriate switch. Connect the discrete output
to a relay. These discrete inputs/outputs are not required for the HR-3P to have
some functionality, but usually you will want to use at least one of them. These
discrete input and output are intended to operate using the power from the HR­3P. Do not supply any power to the discrete input/outputs. You simply need to
open or close the circuit between a discrete and the ground connection provided
on the discrete input/output terminal.

5. Connect the HR-3P to the projector via a crossover serial cable or a straight
through serial cable depending on the projectors pinout.

Operation

The HR-3P is designed to send a string of commands that you create to a projector or
other device via a serial interface anytime 1 of 7 events occurs. The following is a list of
each event and the conditions necessary to facilitate each event:

1. When any video is first detected, the discrete output will be pulled low and the
Video First Detected

2. When Discrete Input transitions from a high to a low signal, the HR-3P will send
the Discrete OFF

3. When Discrete Input transitions from a low to a high signal, the HR-3P will send
the Discrete ON

4. When the VGA video input is selected, the HR-3P will send the VGA Input Active
string out the serial port.

5. When the Composite video input is selected, the HR-3P will send the Composite
Input Active string out the serial port.

6. When the S-Video input is selected, the HR-3P will send the S-Video Input Active
string out the serial port.

7. When no video inputs are active, the HR-3P will send the No Input Active
out the serial port and set the discrete output high.

Each of these 7 strings can have a maximum of 30 characters and minimum of 0
characters. Within each string wait times can be inserted. Each wait can be a maximum
wait time of 16 hrs, 59 min, 59 sec. Each wait takes 3 characters so a maximum of 8 waits
is possible per string. (3 characters x 8 waits = 24 characters) Non-printing control
characters may also be inserted into the strings. The following is a list of the possible
control characters and their corresponding hexadecimal values.
