SP[Dev,Chan] Transmit single IR code pulse. This command will pulse the actual IR code. Pulse time is set by the CTON and CTOF commands. Variable: Dev = 1-4, Chan = 1-252 Example: SP[1,2] Transmits command number 2 pulses to device 1. RS-232 Protocol Commands (Channel Pulse Time) RS-232 Protocol Commands (Channel Pulse Time) Command CTOF(Dev,Time) Description Set the channel's off-time pulse in tenths of a second. Default time is 5 (0.5 second). Time is stored in non-volatile RAM. Variable: Dev = 1-4, Time = 1-255 Example: CTOF(1,10) Sets channel off-time pulse to one second on device 1. CTON(Dev,Time) Set the channel's on-time pulse in tenths of a second. Default time is 5 (0.5 second). Time is stored in non-volatile RAM. Variable: Dev = 1-4, Time = 1-255 Example: CTON(1,10) Sets on-time pulse to 1 second on device 1. RS-232 Protocol Commands (Carrier) RS-232 Protocol Commands (Carrier) Command CAROFF(Dev) Description Disable carrier from responding until a CARON command is received. This command overrides the DIP switch setting on the front panel. Variable: Dev = 1-4 CARON(Dev) Enable the carrier to respond according to DIP switch settings on the front panel.
