Configuration Considerations

You should be aware of the following considerations if you intend to configure Digi One/PortServer TS 2/4 to

handle printers.

Using RealPort

RealPort, a feature that allows network-based host systems to use the ports of the Digi One/PortServer TS 2/4 as

though they were the host system’s own ports, is an easy and efficient way for printers to use Digi

One/PortServer TS 2/4 ports. For information on this option, see "Configuring Ports: Web Interface" on page 17.

Determining Your Printer’s Flow Control Requirements

If you set the Digi One/PortServer TS 2/4 flow control parameters incorrectly, the printer may not print all data

sent to it. Hardware flow control should only be used in environments with a lot of electronic interferance, such

as a machine shop or where a printer cable exceeds a range of 75 feet. Software flow control is used in most

normal printing situations.

Flow Control Tips

Here are some tips to ensure that your printer performs as expected:

• If flow control is necessary, ensure that the printer and Digi One/PortServer TS 2/4 use the same flow control

scheme.

• Some printers that use hardware flow control issue the DTR (data terminal ready) signal when they are ready

for data. If so, the DTR pin on the cable from the printer must be wired to an input on the Digi One/PortServer
