XStream-PKG-E™ Ethernet RF Modem – Product Manual v4.2A

Telnet Loopback Test

MaxStream Wireless links can be tested by connecting to the specific IP address and port

number.

Test a Wireless Link (Telnet Connection):

1. Follow steps in the “XStream-PKG-E Ethernet RF Modem Discovery” section [page 8].

2. Setup hardware as shown in the ‘Hardware Setup for Loopback Test’ section of previous

page [Figure 8].

3. If using Windows: Select (Start Æ Run); then type “cmd” (without quotation marks) in

the text box of the “Run” dialog box. Then select the “OK” button.

If using Linux or UNIX: Run a command shell.

If using Mac OS X: Run (Applications Æ Utilities Æ Terminal).

4. [Remaining steps are for Windows users]

At the command prompt, type:

telnet xxx.xxx.xxx.xxx 14001 <CR>

(“xxx.xxx.xxx.xxx” is the IP address of the Ethernet RF Modem, “14001” is the port

number and “<CR>” stands for carriage return.) [Figure 10]

5. Begin typing characters into the Telnet session window [Figure 11].

Æ Characters typed should be echoed back to the screen. With each character typed,

the “Data Out” and “Data In” LEDs should flash briefly on each of the PKG RF Modems.

The Wireless link can be double-checked by turning off the XStream-PKG-R RS-232/485

RF Modem (leaving the PKG-E Ethernet RF Modem on) and sending characters. When

the PKG-R is turned off, characters should not be echoed back.
