NTSC or PAL composite video images from TV cameras, video recorders, computers, etc. The SCT-50 can insert up to nine lines of twenty characters each into the video image to add source ID information such as camera number and location for security applications, add measurement data during video data collection, or to simply add text in other video monitoring and display situations. -

You can use any standard male-to-female, one-to-one DB9 cable 4. If you are connecting more than one SCT-50 to the serial port, use another DB9 cable to connect between units. You can also purchase special extra short 1' DB9 SCT-50 cables from HORITA. Routing of the serial cables to and between the SCT-50 units themselves can be in any order. -
Page 6: Power Up
SCT-50 is powered up. When the SCT-50 is initially powered up, it operates in the "display" mode to display the time and date and any user source ID information entered. The POSITION and CHAR switches operate to provide quick and convenient control of the display's... -
Page 7: Mode Flow Diagram Explanation
The SCT-50 can be operated locally using the front panel switches or from both the switches and the PC to enter text and setup information. Operation is first described for entering and changing "setup" data, then entering and editing text using the SCT-50 front panel switches. -

SCT-50 for serial communications with PC. Note that setting the SCT-50 address to "00" places it in the "promiscuous" mode which enables it to respond to all information sent via the serial port from the computer, ignoring any specific SCT-50 address. -

Y = Reset SCT-50 system System reset initializes all variable data in the SCT-50 to default values. A hardware selected SYSTEM RESET function is accessible by powering up the SCT-50 while holding the MODE switch in the "SETUP" position, then releasing it. -
Page 10: Time Setup Menu
When the starting position of the time display is changed via actuating the CHAR switch while the "START POSITION" menu item is selected, the SCT-50 temporarily exits the TIME SETUP menu to show the display screen. Further actuation of the CHAR switch moves the position of the time display on a character by character basis in a serpentine fashion so that you can observe its actual position within your normal video display. -

When the starting position of the date display is changed via actuating the CHAR switch while the "START POSITION" menu item is selected, the SCT-50 temporarily exits the DATE SETUP menu to show the display screen. Further actuation of the CHAR... -

4.11 Selecting Local Titling Mode and Entering and Editing Data. To select the text entry TITLE mode for the SCT-50, actuate and release the MODE switch to TITLE until the front panel LED flashes at about once per second and the screen displays a flashing cursor. The flashing cursor shows the position of where the next character will be entered. - Page 13 These switches operate in much the same manner as those found on the simple titlers on many camcorders. The POSITION "arrow" switches select a character's position, and the CHAR "+/-" switches select a particular character from various numeric, alpha, punctuation, and math symbols. You can actuate a switch for a single selection at a time, or hold it down for 2-seconds and cause automatic and rapid selection.

NOTE: At 9600 baud the number of SCT-50 units that can be operated by a single serial port is at least 100 units. Also note that there are active RS-232 repeater circuits in each SCT-50 and this requires that power must be applied to all of the SCT-50 units that are connected together and operating from a single PC serial port so that the serial data can proceed from unit to unit. -
Page 16: Serial Command Set
5.5 Serial Command Set The following list shows all of the serial commands and data that can be sent to operate an SCT-50 via its serial port. As can be seen, an address requires two (ASCII) bytes of data, a command requires two bytes, and any subsequent data itself can be none or one or more bytes. -

The serial data to be sent to the SCT-50 is: Escape, Address, Command. As described earlier, the DISPLAY OFF command is decimal "08", and assuming the address of the SCT-50 is set to "01", the sequence of serial data sent to the SCT-50 to turn the... -
