goTenna Pro-X2m Integration and Set Up
Introduction
The Pro-X2m is the modular variant of the Pro-X2 mobile mesh radio, designed specifically for seamless, rapid integration into third-party platforms. The Pro-X2m is intended to ease integration of the goTenna mesh networking capabilities across a wide variety of systems, making it ideal for adaptable communications solutions in demanding environments. The Pro-X2m’s modular mechanical design ensures easy installation and compatibility, enabling third-party platforms to integrate advanced connectivity with minimal modification. The Pro-X2m’s power system has been redesigned, removing the internal batteries and accepting 9-32 VDC nominal input voltage. This alleviates the need for complicated DC-to-DC converters or adaptation to USB 5v power. On land, at sea, or in the air—even with autonomous systems—the Pro-X2m makes goTenna mesh networking integration simple and reliable.
- Purpose: This document is meant to outline the Pro-X2m interfaces and methods of integration.
Audience: Intended for qualified integrators familiar with radio frequency (RF) compliance, thermal management, and electro-mechanical installation.
ICD Reference: Qualified integrators may contact support@goTenna.com for the full electro-mechanical ICD, if necessary for integration. It should be noted, however, that this not a board level product and disassembly will void any warranty and support for the product.

Safety and Handling Precautions
- Electrostatic Discharge (ESD): Ensure anti-static measures are in place.
- Handling and Orientation: Hold the Pro-X2m by its edges; follow orientation specifications to prevent connector damage.
- Power Off: Confirm the chassis and any connected equipment are fully powered down during initial mating.
Ingress Protection and Environmental
IP Rating: While the PCBs of this device are conformally coated, this device is not protected against intrusion. Ingress protection is the requirement of the platform integrator and the operational employer. The Pro-X2m device itself has IP30 rating, providing protection against foreign objects 2.5 mm in diameter and no water protection. Any requirements for a higher IP rating are the responsibility of the platform integrator.
Thermal Management: This device contains NO active heating, cooling, or pressurization features. The environmental hardening of this device is the responsibility of the platform integrator and the operational Employer.
Required Tools
Tools: There is no required tooling for the use and integration of this device. This device is meant to be integrated by hand with limited resources by the platform integrator. Be mindful of over torquing, if using wrenches on the antenna ports. Any additional integration reinforcement is executed at the discretion and risk of the platform integrator and the operational employer.
Stop-gap and Power Continuity
This device does not contain an internal battery. Power continuity for stop-gap operations is the responsibility of the platform integrator and operational employer. If power from the integration platform fails, operations of this device will subsequently fail until power can be restored.

Rail System 
Step-by-Step Mechanical Integration
Step 1: Prepare the Chassis
*goTenna’s Pro-X2m Reference Chassis is depicted here; integrator chasses will vary significantly 
- Cleaning: Clean mating interfaces from debris and obstacles
- Slot Preparation: Verify the slot matches tolerances, and remove any protective covers or dust.
- Dimensionality: Check to ensure that the Pro-X2m dimensions are compatible with the platform provider chassis. If the Pro-X2m and the Chassis are not compatible along all dimensions then an additional integration frame will be required. Additional integration requirements are the responsibility of the platform provider and operational deployer.
Step 2: Insert the Pro-X2m and Secure 
- Ensure alignment: Ensure The frontplane with RF out is exposed to the user while the backplane with power is aligned with the chassis power interface. Utilize a locking or latching mechanism to ensure the Pro-X2m remains properly seated.
- Guide Rails: Align with specified tolerances, ±0.05mm, ensuring a secure but low-resistance insertion.
- Insertion Force: The Pro-X2m should slide into the chassis with minimal force. Excessive force may indicate misalignment.
Step 3a: Connect Power Option-1 
- Connections: Insert power cable, 2×2 Molex (shown with guide marker toward the top of the device), per ICD specifications.
- Power Path: A four position (2×2) Molex Connector (Molex P/N 0015246043s) on the back of the Pro-X2m will connect to a locking cable harness assembly provided by the integrator (suggested mating connector Molex P/N 39013048).
- Route and Fix Cables: Ensure that all cables are routed and secured to avoid catching or accidental disturbance while in operation.
- Fastening Points: If the Integrator designed chassis secures the Pro-X2m via any of the threaded holes found on the side and bottom faces. Use designated #6-32 screws and torque them to a torque of 4in-lbs to secure the sled without over-tightening. The bottom four threaded #6-32 holes have a thread depth of 0.125 inches. The four threaded #6-32 holes located on the sides of the Pro-X2m enclosure have a thread depth of 0.175 inches. Lengths of screws need to accommodate the thickness of the Integrator designed enclosure.
- Verify: Check that all connections are secure.
Step 3b: Connect Power Option 2 
- Connections: Insert power cable, 2×2 Molex Power Connector and Mounting Panel, onto the back plane of the reference chassis ensuring the alignment of the plate , connector and cover, and tighten the four (4) #2-56 ⅜” screws to a torque of 3 in-lbs. The push-in connector is now installed.
- Power Path: A four position (2×2) Molex Connector (Molex P/N 0015246043s) on the back of the Pro-X2m connects to a push-in 4 position receptacle connector provided by the integrator (suggested mating Molex P/N 015247043) as shown above. Integrators must ensure this location relative to the Pro-X2m for proper connectivity (See Reference Chassis).
- Fastening Points: If the Integrator designed chassis secures the Pro-X2m via any of the threaded holes found on the side and bottom faces. Use designated #6-32 screws and torque them to a torque of 4in-lbs to secure the sled without over-tightening. The bottom four threaded #6-32 holes have a thread depth of 0.125 inches. The four threaded #6-32 holes located on the sides of the Pro-X2m enclosure have a thread depth of 0.175 inches. Lengths of screws need to accommodate the thickness of the Integrator designed enclosure.
- Verify: Check that all connections are secure. Integrators should ensure that the keep out zone on the back plane is free from obstruction.
Step 4: External Antennas / Cables 
- *The antenna depicted is merely an example. As the Pro-X2m is itself not environmentally hardened it is assumed that a wired antenna connection will be used for a band-appropriate antenna dislocated from the integrated chassis.
- Antenna Considerations: Ensure that the antenna is placed with optimal line of sight (LoS), free of RF obstacles, and away from other transmitters. When using a monopole antenna ensure that a ground plane is at least ¼ wavelength in radius of the operational frequency. If Bluetooth connectivity is desired attach external Bluetooth antenna to reverse polarity SMA connector on the right side of the front face. Attach RF antenna, or RF extension cable to an external antenna, to the SMA connector on the left. Hand tighten.
- *Antennas must maintain compliance with FCC Part 05.
