Safety

confirmation_required_for: []
interlocks:
  - DIP switch 2 must be up for Video Shutdown Delay command to function
  - Only one fiber optic cable connected means RS-232 reports from controlled device will not be received
  - Install both fiber optic cables for full functionality
  - Daisy chain mode (DIP switch 1 up) supports up to 10 receivers

Notes

RS-232 over fiber supports up to 115200 baud. Timeout: pauses of 10 seconds or longer between command ASCII characters result in command abort. All SIS responses end with CR/LF (][). Error codes: E10=Invalid command, E11=Invalid preset, E13=Invalid parameter, E14=Invalid command for this configuration.
