task one time -- once the address has been configured, the SX-550 can be accessed from any computer
on the network that has the appropriate privileges. The steps are as follows:
1. If your network has a DHCP server and you can use an Ethernet connection to the SX-550:
a. Make sure your PC is connected and has access to your network.
b. Connect an Ethernet cable from your network hub to the SX-550 (if you have a wireless
SX-550 and do not have hardwired capabilities, then you must go to Step 4 below for
setup instructions).
c. Power on the SX-550.
d. The administration program on most DHCP servers logs the IP address and MAC
address of each DHCP client. The MAC address of the SX-550 can be found on the
label affixed to the unit. If your DHCP server has logged this information, write down the
IP address of the SX-550 for future reference. You are now ready to configure the SX-
550 (skip the remainder of this section).
e. If your DHCP server does not provide client information or if you do not have access to
the DHCP server, then you can get the IP address by connecting a serial device such as
a printer, a Windows PC running HyperTerminal, or another serial device capable of
printing ASCII characters to serial port 1 on the SX-550 (the cable supplied with the SX-
550-6900 Evaluation Daughtercard will work with many such devices). If you are not
using the Evaluation Daughtercard, then you must provide the appropriate cable to
connect pins 9, 11, and one of the ground pins on the OEM header to the terminal
(transmit data on the SX-550 must connect to receive data on the terminal, and vice-
versa). Your serial device must be set at 115.2Kbps, 8-bit character size, and no parity.
f. With the serial device and SX-550 switched on and ready, press the Test button on the
SX-550-6900 Evaluation Daughtercard, or short GPIO7 on the OEM header to ground
(4.7 K-ohm pull-up resistor connected to +3.3 VDC). This will cause the SX-550
configuration data to be sent to the connected serial device. The serial device should
display or print the current IP address assigned to the SX-550 by your network DHCP
service. Write down this address for future reference. You are now ready to configure the
SX-550 (skip the remainder of this section).
2. If you can connect the SX-550 via Ethernet but do not have a DHCP server, then you must use
the following procedure for the first-time IP configuration of the SX-550.
a. Make sure your PC is connected and has access to your network
b. Connect an Ethernet cable from your network hub to the SX-550. The SX-550 must be
on the same network segment as the PC (that is, there can be no router between the SX-
550 and the PC).
c. From the Windows Command Prompt (MS-DOS Prompt), the Mac OS X Terminal Utility,
or the UNIX/Linux command line, enter the command
arp –s ipaddress macaddress
ping ipaddress
Where ipaddress is the desired IP address of the SX-550 and macaddress is the
MAC address of the SX-550 (found on the label affixed to the SX-550). For
example:
arp –s 192.168.5.53 00:40:17:00:00:01
ping 192.168.5.53
Note that Windows systems use the format xx-xx-xx-xx-xx-x x for the MAC
