SRP-350/352plusA&C

Note: Minimum conductor construction must be stranded tinned copper.

To minimize end user termination problems, USB uses a keyed connector protocol. The physical difference in the Series A and B connectors insures proper end user connectivity. The A connector is the principle means of connecting USB devices directly to a host or to the downstream port of a hub. All USB devices must have the standard Series A connector specified in this chapter. The B connector allows device vendors to provide a standard detachable cable. This facilitates end user cable replacement.

Figure 2-10 illustrates the keyed connector protocol.

The following list explains how the plugs and receptacles can be mated:

Series “A” receptacle mates with a Series “A” plug. Electrically, Series “A” receptacles function as outputs from host systems and/or hubs.

Series “A” plug mates with a Series “A” receptacle. The Series “A” plug always is oriented towards the host system.

Series “B” receptacle mates with a Series “B” plug (male). Electrically, Series “B” receptacles function as inputs to hubs or devices.

Series “B” plug mates with a Series “B” receptacle. The Series “B” plug is always oriented towards the USB hub or device.
