External power

The MPS566 receiver does not have an internal battery and must be powered by an external power source. Sources of external power include:

AC power. See Accessories.
DC power:
- A 12 V DC source can be connected using the 7-pin LEMO or the DB26 connector on the back panel. See Cables.
- A external USB-PD power pack (see below) can be connected using the USB-C connector on the front panel. See Step 2. Connect the USB power.

The receiver does not support Power over Ethernet (PoE).

The Activity page on the receiver web interface displays the power source information.

Supported power cables

For information on the power cables that are available to purchase, see Cables.

External USB power pack

The requirements for a locally sourced USB-PD power pack are:

USB-PD (power distribution)
USB-C connector
Capable of at least 15 V at 2 A (30 W). As a general rule it should support USB-C laptops with PD (most laptops require 15 V to 20 V)

Troubleshooting tips for external USB power packs

Sometimes the power pack goes into 'sleep' mode and does not get used.

This sleep behavior is from the USB pack. Some manufacturers' packs go to sleep if there is no current draw. It is possible for the receiver to intermittently use power from the pack. Every manufacturers' sleep timer is different and is not standardized.

If a 5 V / 3 A (15 W) power pack is used:

the power profiles are not reliably detected.
the power pack can go to sleep and become ineffective if it is not the active power source.
the receiver operation may not be reliable under all operational conditions.

If a 15 V / 2 A (30 W) power pack is used:

the power pack can go to sleep and become ineffective if it is not the active power source.

Connecting the receiver to a vehicle battery

When connecting an external battery, such as a vehicle battery, to the receiver, be sure to use the Trimble cable with proper over-current protection intended for this purpose, to avoid a safety hazard to the user or damage to the product.

Use caution when connecting battery cable's clip leads to a vehicle battery. Do not allow any metal object or jewelry to connect (short) the battery's positive (+) terminal to either the negative (-) terminal or the metal of the vehicle connected to the battery. This could result in high current, arcing, and high temperatures, exposing the user to possible injury.
