### Configuring a Digi One RealPort or PortServer for RealPort

Use this procedure to configure a Digi One RealPort or PortServer to use RealPort.

1. Access a root prompt on the PortServer using one of the two following methods:

   ##### Method 1 - Unconfigured PortServer:

   Use these steps to access a root prompt on an unconfigured Digi One RealPort or PortServer.

   1. Attach a terminal (or PC with terminal emulation) to port 1 of the Digi One RealPort or PortServer and configure the terminal for VT-100 emulation, 9600 baud, 8 data bits, 1 stop bit, and no parity. Both the PortServer and your peripheral device's power switches must be OFF.

      Note: The PortServer cable must be a crossover cable, if not a null modem cable must be used to connect to the pigtail provided with the PortServer. See the instructions included with the PortServer to properly connect the cable to the PortServer.

   2. Turn on the Digi One RealPort or PortServer and press Return or Enter.
   3. At the login prompt, enter:

      `root`

   4. At the passwd prompt, enter:

      `dbps`

   Note: `dbps` is the default root password. Enter your specific root password if it is different.

   ##### Method 2 - Previously-Configured PortServer:

   Use this method to access a root prompt on a previously-configured Digi One RealPort or PortServer.

   Login to the PortServer as root directly from an attached terminal or by using telnet.

   Note: If a port is configured to bypass the Digi One RealPort or PortServer login, you cannot directly log into the Digi One RealPort or PortServer from that port. Use another port that does not bypass the Digi One RealPort or PortServer login or use telnet to login to the Digi One RealPort or PortServer.

2. Set the Digi One RealPort or PortServer IP address with this command:

   `set config ip=[ipaddress]`

   where [`ipaddress`] is the IP address the Digi One RealPort or PortServer will use.

3. Set any other relevant Digi One RealPort or PortServer set config parameters such as name server, gateway, etc. See the Digi One RealPort and PortServer Configuration and Administration Guide for details on initial PortServer configuration.
4. Check the RealPort TCP port value with one of the following commands:

   Digi One RealPort/PortServer TS 2/4/PortServer II | PortServer I/PortServer TS 8/16
   set tcp | set config

5. The default value is 771. If it is some other port number, change it to 771 with one of the following commands:

   Digi One RealPort/PortServer TS 2/4/PortServer II | PortServer I and PortServer TS 8/16
   set tcp realport=771 | set config realport=771

6. Configure the Digi One RealPort or PortServer ports using RealPort to rp by using the set ports command. The following example configures ports 2 through 16 of a PortServer for RealPort:

   `set ports range=2-16 dev=rp`

7. If 8-pin RJ-45 cables are used on the Digi One RealPort or PortServer, the altpin option should be enabled. The following example enables altpin on ports 2 through 16 of a Digi One RealPort or PortServer:

   `set flow range=2-16 altpin=on`

8. Make sure that all other set flow options are "off". Enter this command to view all the set flow options:

   `set flow range=2-16`

   Use your own range of ports in the previous command. If other set flow options are "on", use a set flow command to change them to "off".

9. Verify the Digi One RealPort or PortServer configuration with these commands:

   `set tcp or set config
   set ports
   set flow`
