KB635: DT300 - Tetherless Operation

This article was last updated on July 31, 2011, 2:56 p.m. | Print Article | Leave Feedback

The DT300 is “InfraReady”. The DT300R can operate tetherless on radio or “infraReady.” Both units are also provided with a cable to attach into LocoNet when required. A 9 volt battery must be used to power both the DT300 and DT300R for tetherless operation. Using DT300 as a tetherless throttle is easy:

1. For Infrared operation, plug in at least one Digitrax IR receiver (UR90 or UR91) to your working LocoNet. Because infrared signals are line of sight, more than one receiver may be necessary for optimal performance in your layout room.

2. For Radio operation, plug in at least one Digitrax Radio Receiver UR91 to your working LocoNet. Most layouts only need one UR91.

3. Install a 9 volt battery in your DT300.

4. Plug your DT300 in to LocoNet and it will verify that at least one infrared and/or radio receiver is connected to LocoNet. The throttle will display either rA or Ir (depending on whether it finds an infrared or radio receiver first) followed by the current LocoNet ID.

This example shows that the DT300 has detected an infrared receiver and that the current LocoNet ID is 03. The throttle has loco addresses 03 and 1280 selected.

5. The DT300 will then log on to the LocoNet ID of the LocoNet it was plugged in to and will begin to operate as a tetherless throttle when you unplug it from LocoNet. When you unplug from LocoNet, the tetherless indicator will come on and the tetherless message will display for a few seconds indicating whether the throttle is running as Ir (infrared) or rA (radio). It will also display the LocoNet ID that the throttle is logged on to.

6. The connection display will be followed by a normal Lo (Loco) mode display with the tetherless indicator lit.
