Ethernet-Serial Server GW21R

 

           

 

Tunneling model 2. Hardware     

 

Prepare necessary cables, hub, power cord and RS232/RS485 connector. 

 

Connect GW21R to Ethernet network via hub/switch or direct connect to host computer through cross 
over cable. 

 

Connect a serial device to a serial port of GW21R, make sure the right connection of either RS-232 or 
RS-485. 

 

Plug in DC9-30V, the buzzer will beep and the RUN LED will blink if GW21R functions normally. 
Please refer to Appendix A.4 to see all of LED messages. 

 

Use 

monitor.exe

 

configuration utility in the product CD or diskette to diagnose GW21R. If it starts up 

successfully, you are able to find the IP and MAC addresses of GW21R. You can change the network 
parameters of GW21R to join your LAN by changing its IP address, gateway IP address and subnet 
mask. 

2.1 Configuration 

Atop GW21R Ethernet-Serial Server is shipped with default settings shown in the following table: 

    Property                                   Default Value                                                                                     

 IP Address 

 10.0.50.100 

 Gateway 

 10.0.0.254 

 Subnet Mask 

 255.255.0.0 

 User Name 

 Admin 

 Password 

 Null 

 COM 1 

 9600,None,8,1,No flow control 

 COM 2 

 9600,None,8,1,No flow control 

  Link 1 

  Type: TCP Server, Listen port 4660 Filter=0.0.0.0 

  Link 2 

  Type: TCP Server, Listen port 4661 Filter=0.0.0.0 

  SysName of SNMP 

  NAME 

  Syslocation of SNMP 

  LOCATE 

 SysContact of SNMP 

 SYSOP 

 

Note: 

Atop provides a default button to restore system settings including IP address, gateway IP address 

and subnet mask etc. to the defaults. Press and hold the default button for 5 seconds till the server 
reboots. 

2.2 Assigning a new IP Address by ARP command2 

ARP –s is used to assign a static IP address of GW21R and add this static entries to the ARP cache of the 
computer, when TCP/IP packet with destination port number 1 is sent to GW21R, it causes the device to 
check its MAC address with IP address, once GW21R finds those two unmatched, it will reboot and 
change to the new IP address which was set by ARP –s command. The following example uses ARP to
