BPM pioneered using socket adapters to increase the usefulness of their programmers. In the “old” days, you had to buy a programmer for each type of device needed . Socket Adapters are the mechanical “bridge” between the programmer’s programming site and the device to be programmed. A software algorithm is needed as well, which directs where the packets of data go. Most programmers sold in the last 15 years or so use adapters.
