CR-SEH
The Console port is an RS-232 serial port that may be used to configure the CR-SEH. Connection to this
port is made with the 9-pin D to RJ-11 serial cable included with the CR-SEH. This is useful when the
default IP address of the CR-SEH cannot be used with the existing network preventing configuration
through the IPHunter utility. See the section
Configuring the CR-SEH
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-SEH. The CR-SEH can accept DC voltages ranging between 12VDC and 30VDC
if alternative power supplies are to be used.
Status Indicators
Figure 2 shows the status indicators on the CR-SHE. The PWR indicator on the front panel indicates that
power is applied to the CR-SEH. The CR-SEH does not have a power switch. Power is applied and
removed to the CR-SEH 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-SEH 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-SEH to other devices through a hub, the CR-SEH 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-SEH is not communicating with
another CR-SEH. 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-SEH, the RF Link LED indicates the CR-SEH has established a connection with the
master CR-SEH. When a slave CR-SEH is powered on, it will take a few seconds for this LED to turn on.
On a master CR-SEH the RF Link LED is on as long as any one Slave is linked.
