following: Bits per second: 19200; Data bits: 8; Parity: None; Stop Bits: 1 and Flow
Control: Hardware (See figure 3). Click OK. (Set the Bits per second to 9600 if you are
using 24XStream-96 modules)
e. Both computers are now set up and ready to communicate.
3. Test Connection
a. Place cursor in HyperTerminal window of Computer 1 and type a message. Notice that
text appears only in the window of Computer 2 and text typed on Computer 2 appears
only on Computer 1. This text is being transferred over the air by the 24XStream
modules.
b. Transfer the file RAT.TXT
i. On Computer 1: Select Transfer menu ->
Send File(or try right-clicking in the
HyperTerminal window). Insert the disk into
the A: drive and enter Filename:
A:\RAT.TXT Select Protocol: Ymodem (See
figure 4). Press Send.
ii. On Computer 2: Select Transfer menu ->
Receive File. Select a folder in which to
place the file and select Protocol: Ymodem
(see figure 5). Press Receive.
iii. The file will begin to transfer and any errors
or retries will be accounted for. Touch the
antennas and move the modules around to
notice that errors or retries do occur under
certain circumstances.
iv. When the transfer completes, open
RAT.TXT on Computer 2 and observe the
pattern of text, it will be easy to see if any
characters were lost or corrupted.
v. Any file can be transferred this way. Use either Xmodem or Ymodem protocol.
Both computers must have the same settings.
c. Try range testing by distancing the two computers from each other. The modules can
send and receive data up to 10 miles line of sight using gain antennas.
4. Problems (Trouble Shooting)
a. Can’t find the HyperTerminal on your computer?
i. Search your hard drive for HyperTrm.exe
ii. Download a free version from http://www.hilgraeve.com
b. Power LED doesn’t illuminate when battery clip is attached?
i. Replace the battery.
c. Cannot connect to the comm port or communication not working?
i. Try selecting another comm port by selecting Properties under the File menu.
ii. If necessary test the comm ports with a null modem cable (cross RX and TX)
between the two computers to verify operation of comm ports.
d. Characters are getting scrambled?
i. Verify that both comm ports are set match the baud rate of the modules being
tested. Probably 9600 baud or 19200 bits per second. Look for the baud rate on
the FCC sticker, 96 or 192 respectively.
