Slave (Server) Mode
:
To establish a connection using unicast or broadcast data
from one or multiple
host computer to a serial device.(Fig. 32)
Notes
:
The configuration is limited by the Local Listening Port (For example, on the SE5002 listening the port
is 4660 which receives data from the Host Computer).

3.4 Assigning new IP Address with ARP commands
ARP (address resolution protocol) commands can be used to assign a static IP address on SE5002 using
its hardware MAC (media access control) address. The MAC address"0060E9-xxxxxx" is printed on the rear
side of device . The following shows how it works on MS-DOS command prompt window.
Example: change IP from 10.0.50.100 to 10.0.50.101,and MAC address being 00-60-e9-11-11-01
Step1:
Add the new host IP to the ARP table
Open Ms-DOS command prompt window
Input
arp -s 10.0.50.101 00-60-E9-11-11-01
(Fig. 33)

Step2:
Change to the new IP via Telnet port 1(Fig. 34)
Input
telnet 10.0.50.101 1
Note
:
Telnet will fail and then SE5002 restarts automatically. Afterward, the new IP address is changed to
10.0.50.101
Step3:
Using the new IP to configure SE5002 via Telnet
Input
telnet 10.0.50.101
Note:
1. Both PC's IP and SE5002 's IP must belong to the same subnet.
2. The changed IP address must be legal; otherwise it will change back to the default value (10.0.50.100)
after restart.
