Host List Configuration
The XPress DR+ scrolls through the host list until it connects to a device listed in the host list
table. After a successful connection, the unit stops trying to connect to any others. If this
connection fails, the unit continues to scroll through the table until the next successful connection.
The host list supports a minimum of 1 and a maximum of 12 entries. Each entry contains an IP
address and a port number.
Note:
The host list is disabled for Manual and Modem Mode. The unit does not accept a
data connection from a remote device when the host list option is enabled.
To configure the unit's host list:
