Connectors and their Pinouts

All of VersaPNT's connectors are provided at the front panel of the unit, below the Status LEDs. The Advanced Military Connectors are keyed for foolproof connectivity and offer a push-pull locking mechanism. Since the connectors are keyed, you should not need to force connectivity. Inspect all connectors and cables for damage prior to connection.

Power connector pinout

Pin Signal
1 VMain (10 to 32 V)
2 -not used-
3 VStandby (10 to 32 V)
4 GND (to Standby)
5 GND (to Main)

This product is designed to handle a maximum voltage of up to 32 VDC. Power supplies with higher voltage or transient/ cranking power will require a power conditioner or surge blocker.

Caution: Reversed polarity can blow an internal fuse that protects the product from damage. Use care when building power cables.

Test any new cables to safely power the unit before connecting your VersaPNT to any other inputs or outputs (such as a GNSS antenna), and before grounding your unit to a vehicle.

Input/Output Connector

VersaPNT has a 26-pin input/output connector that offers 8 software-configurable CHANNELS, plus one fixed DCLS channel, and a USB interface. To learn more about types of interfaces and signals, and how to configure them, see Assigning I/O Pins.

Ethernet Connector

Note: View in mating direction from front.

The Ethernet connector provides two 1GbE network connections, using 8 wires (pinout below).

6 Ethernet_1 C– 14 Ethernet_2 C–
7 Ethernet_1 D+ 15 Ethernet_2 D+
8 Ethernet_1 D– 16 Ethernet_2 D–

It is also possible to wire your connector to 100MbE, using only 4 wires. Contact Tech Support for more information.

Optional I/O Connector

The Optional I/O connector is used in conjunction with the Option Board that is available for VersaPNT. If the unit is not equipped with an Option Board, this connector is not used.

Coaxial Connectors

VersaPNT offers five (5) coaxial connectors, three (3) of which can be configured at the factory to accommodate requirements for e.g., additional 10 MHz outputs. The minimum configuration includes the GNSS antenna and a 10 MHz sinewave output.

Unless otherwise ordered at the factory, all coaxial connectors (aside from the GNSS connection) produce a 10MHz output that can be all disabled through the Web UI..

All coaxial connectors are standard SMA connectors. Avoid tightening past the maximum torque.

Mating Connector Plugs

The table below lists the part numbers for the mating connectors. The connectors can be ordered through Spectracom or ODU-USA Inc. All connectors are circular ODU AMC® "mil-type" connectors.
