4.3.2 Installing TD220X Firmware by TFTP
To use this function the user will need:
A PC with a TFTP server running.
The IP address of the PC running the TFTP server.
If you do not know your computer's address on a Windows PC, you can use the RUN function from
the Start menu and enter winipcfg or ipcfg to determine your local PC's IP address. The IP address of
the radio can be found on the Starting Information Screen. (See Page 24.) A TFTP server can be
found on the MDS web site at:
http://supportcentral.ge.com/products/sup_products.asp?prod_id=181796
4.3.3 Upload Procedure
To upload a new firmware file (tdx-krmd-X_Y_Z.mpk) into the TD220X unit use the following
procedure:
1.
Launch a TFTP server on a PC connected either directly or via a LAN to the Ethernet port
(LAN) of the radio. On the Options tab, set the outgoing path to the directory containing the
firmware image file.
2.
Connect to the radio's Menu System by whichever means is convenient: Telnet via the LAN
or Terminal emulator via the COM1 port.
3.
Go to the Reprogramming Menu.
(Starting Menu->Main Menu>Maintenance Menu>Reprogramming Menu)
4.
Fill in the information for the:
TFTP Host Address – IP Address of the server (host computer) running the TFTP
o
server.
Retrieve File – Name of the file (tdx-krmd-X.Y.Z.mpk) to be pulled from the TFTP
o
server holding the firmware file.
5.
Pull the firmware file through the TFTP server into the TD220X radio.
(Note: the uploaded firmware image file replaces the "Inactive Image" file and
be automatically verified.)
6.
Reboot the TD220X radio.
7.
Test the radio for normal operation.
8.
End of procedure.
4.4 Set Up a GPS Base Unit
1.
If not already done, complete steps from 4.2 above.
2.
Connect the RS-232 NMEA serial data output from the GPS receiver to the Base Radio via
the radio's COM2 port. Drive serial data into the radio on DB-25 pin 2.
3.
Connect the GPS's PPS output to the Base Radio. Drive TTL into the radio on DB-25 pin 23.
4.
Log in to the radio.
5.
Go to the GPS Configuration menu.
6.
Verify that the GPS NMEA Baud Rate and PPS Polarity match the connected GPS.
7.
Go to the System Configuration menu.
8.
Set the timing source to GPS and reboot if necessary.
9.
Set the STFP radio ID. Set to 64 (decimal) to match the configuration in the tests below.
10. Set the IP Port on which the base will receive STFP messages from the Communication
Manager.
11. Set the IP Address of the Communication Manager to which timing markers and messages
received from mobiles should be sent.
12. Set the epoch size to match the same value configured on the neighboring radios and
reboot if necessary.
13. Set the STFP slot delay as necessary. This number, multiplied by 125ms, represents the slot
delay allowed from when a timing marker is sent to the Communication Manager to when a
data message must be received from the Communication Manager. For most cases the
default value of 2 should suffice.
