Node Adapter

Node Adapter V6

Firmware Updater PCB Information Stand alone repeater Mod. Info.

Node_update_client V02.08 of CentOS5 is available now.

V06.56 (test version) is available. I changed the default value of the header genearation switch from on to off. Also, I changed the memory allocation more. If you have time. please test it and report me. If you are interesting to use V06.62, please use "node_update_client -p 889" command. (You must use the V02.08 or later of node_update_client. Please check the version of your node_update_client. If you don't have V02.08 or later, please re-download it.)

I found some bug on node_update_client.exe. Latest version is V02.08. If you do not have, please re-download the node_update_client.zip.

I found some bug on node_update_client.exe. Latest version is V02.02. If you do not have, please re-download the node_update_client.zip.(05/20/2011

Latest version is V06.54. (09/17/2011)

I added the switch for header generation. If you do not like the RF header generation, please uncheck this switch. V06.42 or later Setting program is V04.02.

If you use the node adapter at noisy place, please update to V06.54 or later.
PTT lock problem was solved. Fixed version is V06.36.

0. I added the alternate header generation logic. V06.62 only (If adapter does not receive the rf header, adapter picks up the header infromation from slow data field.)
1. I fixed PTT lock on repeater mode V06.54.
2. I fixed COS off problem V06.54.
3. I changed the fedault rs232c speed from 19200bps to 38400bps. V06.53
4. I fixed bug in S/N squlech timing.
5. I added miner change for COS routine. V06.40
6. Timing error was fixed for COS ON/OFF.
7. I fxed small bug in RS232C, If you do not use RS232C, you don't need to update.
8. I changed update method for firmware. Please download the node_update_client.zip (include node_update_client.exe and fw_update.exe). And run the "node_update_client.exe" with internet connection. This program is online update program.
9. I deleted the pre and post bit pattern setting. No more support this setting. Do not use this setting command on your application program.

If your PC does not detect the node adapter, please delete the registory of node adapter with regedit program.
If you use S/N squelch, please S/N Squelch is setted from 400 or more big value. If you get the generated header only, please reduce this value.

I added Vender ID change logic after V06.20 and V07.05. Therefore, if application writer will add the Vender ID and Product ID changing logic, you can use the USB driver installer of Pruftechnik for VISTA and Windows 7 64bits. (See USB Driver page)

USB Hub user: If you got the R2D2, please remove the USB Hub and connect directly to PC.

Upgrade from V05.xx user: Do not forget the modification of your board. See Mod. Info.

Sold out!
V7 board is available now. See V7 page.

I found a bug in Beacon routine of V06.17. ~~I alredy sent new firmware(V06.20) to each user. If you did not receive new firmware, please contact me.~~

Information
1. USB type bootloader is supported (You can update the PIC program at your home without PIC programmer.)
2. RS232C is supported (38400bps 8bits None parity 1 stop bit) This is not slow data port. You can control the node adapter thru this port insted of USB. (see Command format and RF received sample) Also, NodeDisplay uses this port.
3. Full speed mode (USB 2.0) only. (No more support low speed mode.)
4. Restore the initial default value.
5. Still use V02.06 PCB.
6. You can change the Product ID thru usb command. You can use multi node adapter cards on one PC.
7. No more need option pic for standalone repeater mode.

Firmware Update Programs
Someone miss used this program. Therefore I added some check logic. Please re-download and use new version.

Do not use PIC programmer. You must use this update program. And you must set the normal mode (not repeater mode) of SW4.

node_update_client.02.09.zip (include node_update_client.exe and fw_update.exe)
node_update_client (Linux version libusb-1.0)
node_update_client 02.08 (CentOS5 static link version 08/12/2011)

Manula of node_update_client (update 07/04/2011)

This update program is online update program. Also, you must unpack and run those programs on writeable directory. This update program uses port 888. No more support the mailing of new firmware.

You must set normal mode (not repeatermode) of SW5.
If you could not run the update program, please try the following sequence.

1. Put the update hex file (node_n.hex) on same directory of update program.
2. Connect pin 1 and pin 28 of PIC18F2550 to GND.
3. Disconnect pin 1 of PIC18F2550 from GND.
4. Wait 3 or 4 seconds after step 3. Disconnect pin 28 of PIC18F2550 from GND.
5. If COS LED is ON, go next step. If COS LED is OFF, retry from step 2.
6. Run update program.

When you ran fw_update.exe, you got the following messages.
DV Firmware Updater flash erasing: DONE.
DV Firmware Updater id programming: FAILED.
Failed to read HID buffer.
Operation aborted.

This messages mean "borken the bootloader". Therefore, please send me your board/box, I will repair it.

Product ID setting program (Linux version only)
Product ID setting program for libusb-0.1.xx (static link version) 12/03/2009

Linux user:
If you got the error code -71 on 2.6.xx kernel, please execute following command.

echo -1 > /sys/module/usbcore/parameters/autosuspend

Own program (application) writter:

If you use follwong command, Please delete those command. Because I deleted those command after V06.25 and V07.25. Also, I use those value for another command after V06.40 and V07.40.

#define SET_PreBitPattern 0xe0
#define SET_PostBitPattern 0xe1
#define GET_PreBitPattern 0xe2
#define GET_PostBitPattern 0xe3

I added some dv detection logic. When Node adapter does not receive the RF header but detectes the re-sync signal, adapter geneates the RF header (that is same as last RF header.) Also, when adapter generate the RF header, adapter sets the 7th bit of satatus byte. (This detection logic is same as ICOM's rig.) If you don't like this logic, please check the 7th bit. and ignore the RF header

1. If you make your own internet apllication using node adapter, you must support the jitter buffer and reconstruction logic of UDP packet.
2. You must impute the loss packet. Because, sometimes the UDP packet does not come original sequence and same delay time.
3. When TX buffer of node adapter is empty, node adapter sets the PTT off. Because, DV strema is synconus signal. Therefore, you must send the dv stream without interrupt. (You must send 12 bytes with excat 20m secund interval or store the enough bytes in TX buffer.)
4. When your application program get a error from "PTT ON" command, you must re-execute the "PTT ON" command. (Still node adapter is running the "PTT OFF" sequence.)

libusb-win32-0.1.xx user
If you got -5(return code) of PUT_DATA command, please retry same command after 10 20 mSecond. This error code(-5) of PUT_DATA is "TX buffer is full".
libusb-0.1.xx user
If you got -32(return code) of PUT_DATA command, please retry same command after 10 or 20 mSecond. This error code(-32) of PUT_DATA is "TX buffer is full".
libusb-1.xx user
If you got -32 (return code) from usb_control_msg command, the pipe between PC and Node adapter was borekn. If you got this, you could not access the USB driver (libusb-win32 or libusb) more. This conndition occured when you re-executed the former usb command with short interval. You must delay to re-execute at least 1 mSecond (5mSecond or more is fine.). This is the physical requirement (low level layer) of USB interface. (This is not Node adapter problem.) Also, when you will execute the usb_control_msg commands with short interval, you will get this problem. And you must check the return code of all usb_control_msg commands.

Important notice:
Many people have the trouble of 24MHz Xtal. Therefore, I change the disribution method of the PCB and pre-programmed PIC. I distribute the complete assembled PCB or pre-assembled the USB part with pre-programmed PIC PCB only.

Price: (Changed 12/23/2009)
Complete assembled PCB is $120 (include registered mail fee).
PCB + PIC is $30 (preassembled PIC and USB psrts only. Include registered mail fee).

Note:
This price is included the future update of V06.xx firmware.
I do not distribute the programmed PIC. I distribute the above boards only.
Current version of PIC is V06.17. And PIC has "code protect". So, do not modify this pic. If you do it, all data of pic is erased automatically.
If you have V05.xx PIC or V05.xx PIC mounted board, plesae send me the V05.xx PIC or board, I will re-program the bootloader and send back to you. (free of charge) Please contact me before you will send your PIC or borad. Do not send me the new PIC. I do not accept new PICs.
