### Device Names

Use the information on this page to determine which device to use for a particular Digi port.

During the driver installation, Digi devices are created in the /dev directory. There are two device types: dial-in and dial-out. The table below shows the device naming conventions for EtherLite and SCSI Terminal Server.

Note: Not all operating systems support both EtherLite and SCSI Terminal Server.

Device Type | Format | Device Information
Dial-In: EtherLite | ttyNyz | tty is constant. N is constant, and always uppercase for Dial-In connections. y is the unit number, which is the numerical identifier assigned to each EtherLite unit as it is installed. z is the port number. Use 0-9 for ports 1-10; use a-v for ports 11-32. A ttyNyz device is usually a dial-in device. These devices wait for the carrier signal before opening. Example: ttyN23 is the third port on EtherLite unit #2.
Dial-Out: EtherLite | ttynyz | tty is constant. n is constant, and always lowercase for Dial-Out connections. y is the unit number, which is the numerical identifier assigned to each EtherLite unit as it is installed. z is the port number. Use 0-9 for ports 1-10; use a-v for ports 11-32. A ttynyz device is usually a dial-in device. These devices do not wait for the carrier signal before opening. Example: ttyn23 is the third port on EtherLite unit #2.
Dial-In: SCSI Terminal Server | ttyXyz | tty is constant. X is an uppercase letter from C-J, which identifies the SCSI bus. C specifies the first (or only) SCSI bus, D specifies the second, etc. y is the SCSI ID number for the SCSI Terminal Server. z is the port number. Use 0-9 for ports 1-10; use a-v for ports 11-32. A ttyXyz device is usually a dial-in device. These devices wait for the carrier signal before opening. Example: ttyC23 is the third port on a SCSI Terminal Server set to SCSI ID #2, connected to the first SCSI bus.
Dial-Out: SCSI Terminal Server | ttyxyz | tty is constant. x is a lowercase letter from c-j, which identifies the SCSI bus. C specifies the first (or only) SCSI bus, D specifies the second, etc. y is the SCSI ID number for the SCSI Terminal Server. z is the port number. A ttyxyz device is usually a dial-in device. These devices do not wait for the carrier signal before opening. Example: ttyc23 is the third port on a SCSI Terminal Server set to SCSI ID #2, connected to the first SCSI bus.
