Base/Rover or Repeater mode selection

You need to tell the radio how you intend to use it in your network:

  • Rover or Base

  • Repeater

  • Base with One Repeater

  • Rx Only

Select Wireless Settings/Radio mode menu.

Setting the transmit and receive frequencies

Your radio comes with your license frequencies already set in your Tx and Rx frequency tables. You can view these using the Wireless setting / Frequency table Rx (or Tx) menu. To set the frequency you want to transmit or receive on, use the Current Channel menu to display and change the current channel.

If you cannot select any channel except for '0', check your Tx and Rx table frequencies. If these are empty, request assistance from your dealer as your license frequencies should be in these tables.

Wireless mode

There are many protocols offered to suit situations where you do not control the base radio settings. You can select the wireless mode in the Wireless mode menu. The radio displays a list of the available wireless modes. Scroll down to your selection and press OK. You can press and hold the scroll buttons to continuously scroll down or up.

Trimble recommends to always use TTv1 at the lowest possible baud rate, depending on the size of the data you need to send. This optimizes range and data integrity.

An over-the-air protocol can be defined by a data format, a modulation, a baud rate, whitening or scrambling, and error correction.

You can select variants by changing each of these settings individually when available if required. See Menus.

The Legacy Protocol Name menu item shows you the description of the selected wireless mode.

For a more complete understanding of the effect of selecting protocols and their variants, see Recommended setup and configuration.

Once you have set your radio, you can save these settings in a profile (go to the Settings Profiles menu). The first setting cannot be modified; it is the default setting for your radio that has been recorded by your dealer.

Selecting the transmission power

Your maximum power transmission depends on your license and country regulations. You can set the transmit power to 1, 5, 10, 25, or 35 W. The higher the power, the bigger the range but the bigger the power consumption. Set the power to the minimum needed to achieve the range you need.

This help contains advice on how to set your power and other parameters to optimize your range, throughput and overall reliability of your radio link.

Your TDL450B radio should now be ready to operate. You can save these settings in a profile for future use by using the Setting Profiles menu.

Setting the radio to receive any frequency

You may require the radio to be set to a different frequency than the one for which you have a license to transmit. To do this, you can set the radio to Rx Only mode (Wireless settings / Radio mode / Rx Only) and select the Rx frequency in the Wireless settings / Rx Frequency menu. You can also select the channel spacing freely in the Wireless settings / Channel bw menu.

To enable transmission when in receive only, select one of the options in the Radio mode menu. This resets your receive frequency and channel spacing.
