Description
With the Flash/Net system, up to 24 computers (as many as 64 when adapters are used) can easily share up to 8 printers using inexpensive 4-wire telephone line in a Bus, Star or Tree topology. Printers can be selected using a manual controller (optional purchase), or software control. To cope with today’s speedy PC systems, Flash/Net has a throughput of up to 22 Kbytes per second – making it faster than any similar network.This advanced power-free printer network eliminates the need for multiple auto switches and heavy, tangled cables. Flash/Net comes in both Centronics and Serial models, which can be intermixed in the same network. Simple installation and ease of operation make this printer-sharing network suitable for all user levels. Simply plug a transmitter unit into the PC’s parallel or serial port; a receiver unit into the printer; connect the units with a 4-wire telephone line (straight-through) and you are ready to go.Features

The components that make up the Flash/Net system are the following:
| Component | Type | Purpose |
| ADP3356 | Centronics Transmitter | Connects to PC’s Parallel port; receives print jobs from the Parallel port and sends them to the Receiver |
| ADP3357&ADP3357-1 | Centronics Receiver | Connects to a parallel printer receives print jobs from the transmitter and passes them on to the printer. The ADP3357-1 has a 1-Meg buffer built into it. |
| ADP3351 | Serial Transmitter | Connects to PC’s COM port; receives print jobs from the COM port and passes them on to the receiver. |
| ADP3354 | Manual Printer Selection Controller (Optional) | Connects to a Transmitter; selects which receiver will get the print job. This provides the easiest selection method – eliminating the need for software. |
