COMPUTER CONNECTIONS
RS-232
Connect the COM port on your computer to one of the 9-pin RS-232 connectors on the P4800 device using a male-to-female serial
cable, as shown in Figure 4.
NOTE: Use only a standard, 9-pin, RS-232 cable wired straight-through. Other types of serial cables that use fewer pins or crossed
wires will not work.

For cable lengths of 50 ft. or more, use an RS-422 serial connection. Unless you have an RS-422 serial port on your computer, you will
need an adapter for your computer’s RS-232 COM port, as shown in Figure 5.

Networked
Up to 16 ShureLink devices, including P4800s, DP11EQs, DFR11EQs, and UA888s can be linked and controlled from one computer.
Connect the ShureLink IN and ShureLink OUT of each device using 5-pin DIN cables (like the one supplied with the P4800), as shown
in Figure 6. The last device in the chain must be connected to the first device (the one connected directly to the computer) to
form a loop.
