SPT

The SPT is available in two basic styles: the SPT-SXY and the SPT-SS. The SPT-SXY includes one serial port configurable for RS-232, RS-422, or RS-485 and a pair of X-Y control ports (X-Y Coax and X-Y Mini XLR). The serial port is used to communicate with other manufacturers' equipment, while the X-Y ports are used to communicate with Harris equipment.

The SPT-SS includes two serial control ports, one configurable for RS-232, RS-422, or RS-485 and the other fixed for RS-232. The SPTs can be configured for a number of different applications including:

Protocol Translation
With the SPT, Harris routing switcher systems can be controlled by other manufacturers' control systems. Conversely, other manufacturers' routers can be controlled by Harris control elements, including the wide variety of Harris control panels and control software.

System Expansion
The SPT can be used in a special Harris to Harris mode to provide source and destination offsets for expanded configurations.

Additional Serial Ports for Harris Routers
The SPT can be used in a special Harris to Harris mode that can be used as a serial to X-Y converter. In this configuration, the SPT provides additional serial ports in a routing system where the serial ports on router frames are already all used.

Utility
The SPT can be configured to simulate a Harris routing system to assist in debugging control software and hardware, or provide for an RS-232 to RS-422 electrical conversion.

The SPT is physically housed in a small plastic box and can be mounted to the side of a rack, or left in-line along a length of cable. All connections including the power connection can be locked so they remain secure.
