# Instrument settings

To view the Instrument settings screen:

- Tap and select Instrument / Instrument settings.
- Tap and hold the instrument icon in the status bar.

Depending on the instrument that the controller is connected to, the following functions may be available:

Instrument details

The available instrument details depend on the connected instrument, but may include:

- Instrument name, Instrument type, Serial number, and Firmware version.

  These details are stored in the job file, and can be output to a report when exporting job data.

- Instrument configuration, which shows information such as the radio variant and the angular accuracy of the connected instrument.

For some instruments, you can tap Name to enter the instrument name.

Wi-Fi channel

If the connected instrument is a Trimble SX10 or SX12 scanning total station, select the required Wi-Fi channel. When connected using Wi-Fi you may see a connection drop of up to 30 seconds when applying this change.

Specifying the channel can be useful when connected over Wi-Fi in congested Wi-Fi environments.

To set the Wi-Fi channel, the instrument must have firmware S2.2.x or later installed.

Wi-Fi HaLow settings

If the connected instrument is a Trimble SX12 scanning total station with Wi-Fi HaLow™, fields for setting up Wi-Fi HaLow communication are shown. To set this up for the first time, connect to the instrument using standard Wi-Fi or using a cable.

To connect to an SX12 using Wi-Fi Halow, Trimble Access must be running on a Trimble controller that has an EMPOWER EM130 Wi-Fi HaLow module. Wi‑Fi HaLow uses a different frequency band to standard Wi-Fi and is available only in the United States, Canada, Australia, and New Zealand.

To configure Wi-Fi HaLow settings:

1. Select the Wi-Fi HaLow mode:

   - High bandwidth is the recommended setting for most situations as it provides the best throughput for large amounts of data, such as scan point clouds, images, and video streaming.

   - Low bandwidth may offer additional range in certain environments with reduced throughput. Low bandwidth offers additional channel options in some regions.

2. Select the Wi-Fi HaLow channel.

   The available channels are determined by the Wi-Fi HaLow mode you have selected. If you selected High bandwidth, available channels with 2 MHz bandwidth are listed. If you selected Low bandwidth, channels with 1 MHz bandwidth are listed.

   To automatically select the best channel in the selected band, tap Auto-select channel. The software scans and assesses the available channels and selects the best available channel, which may be the currently selected one. Once the new channel is selected, tap Accept to reconnect to the instrument on the new channel. If the instrument is currently connected using Wi-Fi HaLow then the connection is dropped while the software reconnects to the instrument using the new channel.

3. Tap Accept to apply your changes.

When connected to the SX12 using Wi-Fi HaLow you may see a connection drop of up to 30 seconds when applying any changes to the Wi‑Fi HaLow settings.

Instrument password

If the connected instrument is a Trimble SX12 scanning total station with firmware S2.8.x or later installed, and Trimble Access is connecting to the instrument using Wi-Fi or Wi-Fi HaLow, you may be prompted to enter the instrument password.

To change the password, tap the Password softkey at the bottom of the Instrument settings screen.

For more information, see Instrument Wi-Fi connections and Instrument password.

PIN lock security

To enable PIN lock security on the instrument, tap PIN and then enter and confirm the PIN. The PIN can be any 4‑digit numeric value except 0000.

When the PIN function is enabled, the Unlock instrument screen appears when connecting to the instrument. Enter the PIN and then tap Accept.

When the PIN has been set, tap PUK and record the number for the PUK (Personal Unblocking Key). Use this number if you have forgotten your PIN. Ten incorrect attempts to unlock the instrument using a PIN results in the instrument being blocked. If this occurs, you are prompted for the PUK code to unblock the instrument.

If the instrument is locked and you don't know your PIN or PUK, contact your Trimble distributor for help.

To change the PIN, tap Instrument / Instrument settings / PIN, enter the current PIN and then enter and confirm the new PIN.

To remove PIN lock security, tap Instrument / Instrument settings / PIN, enter the current PIN and then tap None. The software changes the PIN to 0000, which means that no PIN lock security is set.

PIN lock security can also be enabled using the Security option the face 2 display of the instrument.

Auto focus

When the Auto focus check box is selected, the instrument automatically focuses whenever it automatically turns to a point.

- For the Trimble SX10 or SX12 scanning total station, all cameras except the Telecamera are fixed focus. The Telecamera has auto focus or can be manually focused. See Instrument camera options.
- New instruments are shipped with auto focus calibrated in the factory. When upgrading from an older version of the instrument firmware, you must first calibrate auto focus using the Adjustment / Auto focus calib. function on the instrument face 2 display.
- If heights are not known, the computed slope distance cannot be determined and the instrument will be focused based on the horizontal distance instead.

Reticule illumination

Use the Reticule illumination control to illuminate the crosshair. This is useful when the crosshair is not easily visible, for example when in a tunnel.

Face 2 backlight

To enable the face 2 backlight, select Face 2 backlight.

Service information

Conventional instruments should be serviced regularly. To check when the instrument is due for the next service, tap Instrument / Instrument settings / Service. For some instruments, a service warning message appears when the instrument is due for service. When this message appears, you can still use the instrument, but you should contact your Trimble distributor at your earliest convenience to organize servicing.

Target test

The target test is used primarily in Survey Basic when measuring a distance that is to be displayed as a dead record.

If the instrument is moved more than 30 cm from where the last measurement was observed, the HA and VA are updated but the SD reverts to "?" to avoid mistaking the next target's distance for the previously measured target's distance.
