LedMask command allows setting a bitmask which specifies which relays control the LED indicator used to display whether a relay is latched/powered. The order of the <bitmask> is from most significant bit (MSB) to least significant bit (LSB). Bit 15 (MSB) masks Relay16 through bit 0 (LSB) which masks Relay1, respectively. For each relay to be included in controlling the power LED, set its corresponding bit in the <bitmask> to 1. <bitmask> bits without corresponding configured relay components have no effect and can be ignored.

<bitmask> = bitwise value representing each relay. Values may be entered as either hexadecimal or decimal values (e.g., 0xFFFF = 65535).
0xFFFF (= 1111 1111 1111 1111) All relays control the power LED (default)

LedState must be enabled (i.e., != 0) in order for LedMask to take effect.


  • `LedMask 0xFFFD` Every relay, except Relay2, controls the power LED (0xFFFD = 1111 1111 1111 1101)
  • `LedMask 0x0002` Only Relay 2 controls the power LED (0x0002 = 0000 0000 0000 0010)
