CR-SEB
The Console port is an RS-232 serial port that may be used to configure the CR-SEB. Connection to this
port is made with the 9-pinD to RJ-11 serial cable included with the CR-SEB. This is useful when the
default IP address of the CR-SEB cannot be used with the existing network preventing configuration
through the IPHunter utility. See the section
Configuring the CR-SEB for details of using this port.
The power connector is a 2-pin terminal block connector. The provided AC adapter provides a 12 volt
power level to the CR-SEB. The CR-SEB can accept DC voltages ranging between 12VDC and 30VDC
if alternative power supplies are to be used.
Status Indicators
The PWR indicator on the front panel indicates that power is applied to the CR-SEB. The CR-SEB does
not have a power switch. Power is applied and removed to the CR-SEB by connecting and disconnecting
the power connector.
The Ethernet LEDs include LINK, TXD and RXD. The LINK LED lights when a valid Ethernet
connection is made. The CR-SEB is set up to use a straight through cable to connect to a PC. If a straight
through cable is used to connect the CR-SEB to other devices through a hub, the CR-SEB must be
connected to the uplink port on the hub or the crossover Ethernet cable must be used. TXD and RXD are
indicators of Ethernet data activity. They indicate the transmission and reception of data over the Ethernet
connection. Note that these LEDs can be active even when the CR-SEB is not communicating with
another CR-SEB. When on, t
he XCVR LED on the CR-SEBX indicates the remote radio of the
CR-SEBX is operating properly.
On a slave CR-SEB, the RF Link LED indicates the CR-SEB has established a connection with the
master CR-SEB. When a slave CR-SEB is powered on, it will take a few seconds for this LED to turn on.
On a master CR-SEB the RF Link LED is on as long as any one Slave is linked.
