There are a few restrictions you need to be aware of when you are building your string.
You may not backspace or delete as you are building the string. Doing so will delete the
entire string you have constructed. You may not use the Windows “Paste” function to insert
more than one character at a time. Doing so will result in the string being deleted. You
may only insert a character at the end of the string. If you attempt to enter a string over
25 characters, your string will be deleted. This can be avoided by watching the “File
length:” indicator at the bottom of the screen. Any character input from the keyboard will
increment the File length by 1, same for a Control Character. A wait time will increment
the File length by 3.
Uploading to the HR-3P
After you have selected a baud rate, priority, No Input Active string delay, and strings for
each of the 7 strings, you can then click the “Save and Upload” button and this
configuration will be saved to the configuration file you created or opened at the start and
this configuration will be uploaded to the HR-3P. If you leave any of the strings blank then
a 0 length string will be used meaning nothing will be sent out the serial port for that
event. If you do not specify a delay for the No Input Active string then there will be no
delay before that string is sent out the serial port. The upload procedure should take 4-7
seconds. When it is finished you will see a message indicating the success or failure of the
upload procedure.
Loading or Saving Configurations
You can save or load a configuration file by clicking on the File menu and choosing the
appropriate icon. You can also create a blank, new configuration file from the File menu.
Putting the HR-3P into Operation
After you have successfully uploaded a configuration to the HR-3P, disconnect the HR-3P
from the computer and power it off. Connect the HR-3P to the projector via the serial
interface.
Important!
You may need to use a straight through serial cable (also know as a NULL-modem
cable) (not included) to connect the HR-3P to the device you want to control.
There are 2 types of serial devices:
1. DTE (Data Terminal Equipment) ex. Computer/ PC , HR-3P
2. DCE (Data Communication Equipment) e.g. Serial controlled projector,
modem
