The Cursor is where text entered on the keyboard will appear on the screen The cursor can be positioned through the Arrow keys up down left right or the Enter key starts a new line Normally the cursor is not visible but when a key is pressed including the Shift Control Alt or arrow keys the cursor becomes visible inverting the background and blinking the character at the cursor position After 5 seconds the cursor disappears for normal operation The cursor can be positioned through GPS data fields skipping across the fields Entering Text Text can be entered through the keyboard at the current cursor position moving the cursor left to right up to down to add static titling information to the display Editing Text Editing text is performed with the Backspace and Delete keys Backspace deletes the character at the current cursor position and moves the cursor to the previous character position Delete deletes the character at the current cursor position and moves the cursor to the next cursor position Text Background Text can be entered with a gray background by entering the two key combination Ctrl B and then entering the desired text at the desired position Entering Ctrl B again will toggle the background off again for further text entry Selecting Transparent Text or Opaque Text Mode Text can be displayed as translucent in which the background colors show through the characters or as opaque in which the character2. The supplied power connector permits the installer to fashion the cabling needed for the specific installation Video Source The video source must be NTSC combined video or S Video rather than RF While many devices may have an RF output on a particular TV channel number the VPC uses a true video signal to maintain high signal quality Thus the camera system video output should be connected to the VPC video input Since the VPC carries only video and not RF a separate audio connection to the VCR will be required Video Monitor The VCR video output is connected to the video input of the recording apparatus This IS NOT an RF connection and does not connect to an antenna terminal The monitor only has an antenna connection rather than a video connection then an RFU unit may be required on the video output of the VCR or the VCR may be able to generate a TV RF signal typically channel 3 or 4 An RF connection would then go to the Antenna Terminal of the TV VCR The VCR video input is connected to the VPC video output through a video connection The VCR video output is connected to the Monitor video input GPS Data Connection The normal RS 232 data connection uses the green and red wires Green as a signal ground to the GPS and Red as the data signal from the GPS to the VPC Cabling Cautions Video connections carry a signal between a signal source and a sink of that signal They typically have a characteristic impedance resistance
