selected all the numbers in the Terminal Port. When the Terminal Port entry is 
complete, Locate to Save and press the Enter button.

 A serial connection through the serial port uses a fixed IP ad-

dress: 192.168.168.101. 

To control the 5700i directly through its serial port or Ethernet port, you can use the 
freeware terminal emulation application PuTTY. If you wish to automate control, 
download Plink. Both of these applications are available for free download. Search 
“PuTTY” with Google to find a download site. 

Note that Windows 7 does not install a Telnet Client by default, so you 
must do this manually if you wish to initiate a Telnet connection be-
tween a Windows 7 machine and your Optimod. Refer to:  
  

 

Direct Control Using PuTTY 

A)

 

If you are using a serial connection, establish a Direct Serial Connection be-
tween your computer and the Optimod. See 

Appendix: Setting Up Serial 

Communications

 starting on page 2-61. 

A connection through the serial port uses a fixed IP address: 
192.168.168.101 

B)

 

Start PuTTY. 

The 

S

ESSION

 window appears. 

C)

 

Click the 

T

ELNET

 button, which is hard-wired for Port 23. 

D)

 

In the 

T

ERMINAL

 category, check “Implicit CR in every LF.” 

You should not have to change any other PuTTY Terminal, Window, or 
Connection defaults 

E)

 

Specify the host name or IP address: 

•

 

If you are connecting through the 5700i’s serial port, type 192.168.168.101 
into the “Host Name (or IP address)” field. 

•

 

If you are connecting through the 5700i’s Ethernet interface, type the 
5700i’s IP address into the “Host Name (or IP address)” field. 

The IP address for this connection is the same as the IP address set in step 
(1.B) on page 2-45 and is visible in the
