LED Outputs
Status LED¶
The status LED (STATUS_LED) indicates the status of TiMo module. The LED indicator pin is an output pin capable of sourcing 5mA at the VDD voltage. An appropriate current limiting resistor must be connected in series with the LED. This LED is also used when using the link switch based method of switching flex modes; please refer to page 25 for details.
Receiver¶
Constant off (0V): Not linked to any transmitter
Flashing: off (0V) 100 ms / on (VDD) 100 ms: linked to a transmitter,
but no active radio link
Flashing: off (0V) 900 ms / on (VDD) 100 ms: Active radio link, no DMX
present
Constant on (VDD): Active radio link, DMX data present
Transmitter¶
Flashing: off (0V) 900 ms / on (VDD) 100 ms: Active radio link, no DMX
present
Constant on (VDD): Active radio link, DMX data present
Flashing: off (0V) 100 ms / on (VDD) 100 ms: linking receivers
Flashing: off (0V) 200 ms / on (VDD) 200 ms: unlinking receivers
Linked¶
Receiver¶
The Linked LED (LINKED) indicates whether the TiMo is linked to a transmitter or if it’s available to be linked. High level (VDD) on this pin indicates a linked state; low level (0V) indicates that the TiMo module is not linked.
Transmitter¶
High level (VDD) on this pin indicates an ongoing linking activity; low level (0V) indicates that the TiMo module is currently not performing a linking activity.
RF Link¶
Receiver¶
A high level (VDD) on the RF Link LED output (RF_LINK) indicates that the receiver is within range from the transmitter it is linked to and that an active radio link from the transmitter is present.
Transmitter¶
A high level (VDD) on the RF Link LED output (RF_LINK) indicates that there is an active radio link.
DMX LED¶
The DMX LED (DMX_LED) indicates if a valid DMX stream is received. A high level (VDD) indicates that DMX is present, a low level (0V) indicates that no valid DMX is present.
RDM LED¶
A high level (VDD) on the RDM LED output (RDM_LED) indicates that the TiMo is performing RDM activity.
Radio level¶
TiMo has 5 output signals for controlling radio level LEDs in the form of a bar graph (RDI_LVL0 - RDI_LVL4). Operation of these, and suggestion of LED colors, can be found in the table below. These are only used for receivers.
| Signal name | Suggested LED color | On when signal quality |
|---|---|---|
| RDI_LVL0 | Red | below 10% |
| RDI_LVL1 | Amber / Yellow | above 20% |
| RDI_LVL2 | Green | above 40% |
| RDI_LVL3 | Green | above 60% |
| RDI_LVL4 | Green | above 80% |
