Other Non-Supported Devices
Devices that conform to Hewlett-Packard’s asynchronous protocol and are capable of
being physically connected to the DTC can be controlled through Asynchronous Serial
Communications (ASC). This includes test instruments, data collection devices, etc. To
determine if a device can be non-nailed or if it must be nailed, refer to “Nailed Device”
and “Non-Nailed Device” in this chapter. Contact your Hewlett-Packard support
representative for more information on non-supported devices. Take extreme care when
connecting non-supported devices.
Device Physical Path
Each asynchronous device (excluding the system console, PADs, and Telnet/iX devices) is
connected to a port on an interface card within a DTC; this is the device’s physical path.
The address for the physical path, or the physical device address, consists of identifiers
for the DTC, the interface card, and the port to which the device is connected. Note that
the physical device address can be used to troubleshoot a device and its connection.
