AdNotam CS-101 Display Frame Unit Control Spec

Summary

AdNotam CS-101 Display Frame Unit (DFU) supports remote control through an ASCII-based RS-232 protocol over null-modem serial cable. Spec covers full documented command set: power, boot behavior, signal-loss behavior, sleep timer, keypad and cursor input, volume, mute, media controls, OSD, source selection, picture and audio settings, level controls, and RS-232 acknowledgement control.

Notes

• Command frame: & header, three-byte case-sensitive identifier, optional : or ? separator, optional three-byte value, and CR (0x0D).
• Command and acknowledgement frames are always nine bytes including CR. Spaces are prohibited.
• Values shorter than three bytes are right-padded with *.
• Successful acknowledgement uses % header. Invalid or unavailable command response uses ! header.
• Wait 10 seconds after power-on before sending next command.
• Wait for response before sending next command.
• Wait at least 2 seconds before resending when no response arrives.
• Wait at least 500 ms between commands.
• Wait at least 5 seconds after sending 20 commands.
• Default baud rate is 38400. Baud rate is selectable through OSD service menu from 9600, 19200, and 38400.
• &EXT:*** contains three literal asterisks.
