Motorola RIB Box & Cable Guide

Almoast all analogue Motrola two-way radios utilise the legnedary Motorola RIB box that can be used in conjunction with a RLN4460 test box or stand-alone.

However you intend to use the Motorola ROB box, one thing’s for sure, it’s an incredibly complex subject working out which cable you need for both programming and testing and which for just proghramming (sometime’s that’s the same cable).

This article is intended to guide you through the convolution and simplify this to ensure you find the cable you need.

Note: This article is intended for Australia and New Zealand users only.

Note2: This guide is about the classic RLN4008_ RIB box. RLN1015 SmartRIB is not covered here.
