The LogicBlock is a carbon fiber-nylon composite printed bracket that is used to attach wireless HD receivers to certain SmallHD and TVLogic monitors. 

The LogicBlock is 3D printed in-house using a strong, high-quality carbon fiber-nylon composite material that prints in a natural carbon color, without dyes. The LogicBlock is extremely light, and it won't crack or split. All necessary hardware is included.

SmallHD 702 Series: LogicBlock for SmallHD 702 Series monitors pass power directly through to the monitor without an external cable. Power the HD receiver is supplied via a thin 2-pin Lemo (0B.302) lead.

Universal Receiver: The Universal Receiver option allows most Teradek and similar wireless receivers to be mounted to the LogicBlock.

Lemo Hot-Swap: The 2-pin Lemo (0B.302) input is wired to a hot-swap circuit that automatically switches from the battery plate to the Lemo input (when 12V+ is available). The Lemo is wired Pin-1 GND to match Teradek, Arri, and SmallHD Lemo inputs.

*Batteries not included*

Great for 1st AC

Great product for using a bolt receiver together with a smallHD 503 monitor. Light weight and feels solid, looks like it should stand up to 1st AC abuse. Two minor complaints: - When I received the Logicblock, the cable that connects to the monitor hade been pushed inside the Logicblock and I couldn’t get it out. Support was quick to answer though, and it was an easy fix. - The screws are a bit hard to reach when installing/uninstalling, although a supplied ball end hex key helps.

Thank you for your review. I'm glad the you were easily able to get the 8-pin connector for your 703 out after speaking with our team. We push the connector into the cavity so that it doesn't get damaged in shipping. That connector is an internal board-to-wire connector and is not as robust as a Lemo, but is needed to power the monitor.
