*
, 710 mA max including all
external loading
User output voltage range (available at +VO terminal): 4.40 V min to 5.25 V
max, assumes supplied AC adapter is used
User output current (available at +VO terminal): 10 mA max
Network
Ethernet Connection
Ethernet type: 100 Base-TX, 10 Base-T
Communication rates: 10/100 Mbps, auto-negotiated
Connector : RJ-45, 8 position
Cable length: 100 meters max
Additional parameters: HP Auto-MDIX support
Network Interface
Protocols used: TCP/IP (IPv4 only), UDP
Network ports used: UDP:54211 (discovery), UDP:6234 (bootloader only),
TCP:54211 (commands), TCP:54212 (scan data)
Network IP configuration: DHCP + link-local, DHCP, static, link-local
Network name: E-1608-xxxxxx, where xxxxxx are the lower 6 digits of the device
MAC address
Network name publication: By NBNS (responds to b-node broadcasts, therefore
only available on the local subnet)
* This is the total quiescent current requirement for the device that includes the
LEDs. This does not include any potential loading of the digital I/O bits, +VO
terminal, or the AOUTx outputs.
Network Factory Default Settings

Network Security
Security implementation: TCP sockets are not opened unless application sends
the correct PIN code (stored in non-volatile memory, may be changed by user,
default value 0000)
Number of concurrent sessions: 1
Vulnerabilities: TCP Sequence Number Approximation Vulnerability
LED Displays and the Factory Reset Button
Power LED (top)
3.3 V < V
ext
< 5.9 V: On
V
ext
< 3.3 V, V
ext
> 5.9 V: Off (power fault)
Activity LED (bottom): On when there is a valid host connection and blinks
when a command is received or an AInScan is running.
Ethernet connector LEDs
Left, green: Link/activity indicator; on when there is a valid Ethernet link and
blinks when network activity is detected.
Right, yellow: Speed indicator; on for 100 Mbps, off for 10 Mbps or no link.
Factory reset button: Used to reset the network configuration settings to the
factory default values.
