Tenma 72-2540 low voltage power supply remote control syntax

Serial port settings

  • Baud rate: 9600
  • Parity bit: None
  • Data bit: 8
  • Stop bit: 1
  • Data flow control: None

Command format

  • COMMAND<X>:<NR2>
  • COMMAND<Boolean>

  • <X> Output channel (always 1 in case of a single channel supply 72-2540)
  • <NR1> Digits with an implied decimal point assumed at the right of the least-significant digit. Example: 273 (Integer number)
  • <NR2> Digits with an explicit decimal point. Examples: .273, 0.273
  • <Boolean>: Boolean value 1 or 0.
