The Porter versatile, code activated switch allows one computer to send a code to select one of several devices. The Porter can be configured to match the type of equipment that you have. You do not have to have a PC to use the switch or to configure it. Easy to install, the Porter uses commonly available cables and works with any device with serial or parallel ports. The Porter's serial ports are DB25 and its parallel ports are Centronics.
Receive buffers accept data on all ports simultaneously.
This data can then be read from the master port one at a time. The Porter transmits from buffers on all ports simultaneously. The Porter s buffer is expandable to 256K bytes. The clear buffer command purges all data in a port s buffer. The broadcast feature allows you to send data simultaneously on all ports.
