Programming leads for interconnecting a PC serial port to a serially programmed two-way radio come in a wide variety of model-specific types, most of which contain active components (inverters, level translators etc) - sometimes referred to as a Radio Interface Box or "RIB". There are also a variety of radio connectors in use on the leads. Although in some cases a passive lead can be substituted effectively, the result of this diversity is the accumulation of a large number of active leads and the corresponding increasing investment in essentially duplicated gear.
The larger part of
the componentry - and cost - is (or can easily be made to be) common to
these leads and all the model-dependent attributes (polarity, connector
style, source voltage etc) can be accommodated in a simple
lead from the common interface.
The Skyline Engineering Services Adaptable Programming Interface provides that common interface. It features:
operation from 5V or 8-14V power, supplied at the radio connector. LED indicator to confirm power available.
support for full handshake operation. ‘idiot-proof’ automatic selection of signal polarity, handshake polarity and source voltage with each model-specific passive lead. easy user fabrication of additional passive radio leads as required.
Passive cables have been documented and tested for the following radio types:The version with the PC serial port connection via a 25-pin 'D' connector (left photo) is no longer manufactured. The new version (middle pic above) with a 9-pin serial port 'D' connector is now supplied. Note that the casing on these may be BLACK depending on parts availability at the time of production.
