The Logical Steps to Rescue a PA168Q
  
Aug 14, 2011
After several casual emails with a new user who had a second-hand dead PA168Q last week, he finally wrote: Where is the start point and the end point? How am I supposed to find my way in all these links?? Which one is relevant to my case and which is not? Then, How to send the bin file to the device. I appreciate the help, but it needs to be logical.
I felt frustrated of my PA1688 web work at first, then I realized there must be other new users with second-hand PA1688 devices feeling the same like him. According to Google Analytics, the new visitors percentage in our web site rose from 61.01% to 74.07% in the past 5 months (see image below).
If I were new to PA1688, maybe the logical steps should be:
1. Find a Windows PC, connect PC and PA168Q to a same local network which has DHCP server as 192.168.1.1, and make sure 192.168.1.100 IP address is not used.
2. Download the software API and PA168Q upgrade file, current release version is 1.66. Decompress software API package to C:\Palmh323 and PA168Q upgrade file pa168q_sip_us_166000.bin to C:\Palmh323\bin.
3. Run PalmTool from C:\Palmh323\bin, click Start Debug button to start UDP debug output window, fill 192.168.1.100 to IP Address in Chip control.
4. Press and hold the only key on PA168Q while power up, do it at least twice until it enters safe mode. After entering safe mode, depending on software version, there might be different output in the debug window, and PC can ping PA168Q at 192.168.1.100 with MAC address 00-09-45-00-00-00.
5. Use PalmTool to upgrade from safe mode, click Update Program and select pa168q_sip_us_166000.bin.
After the above steps, PA168Q will reboot. If we are lucky, it might working now. Pick up the handset of the PSTN phone which connected to PA168Q, press the only key on PA168Q, the IP address will be played out in the handset speaker.
There is a known caller ID problem with PA168Q and all other PA1688 based gateway using outside China, perhaps the CID function only work with Chinese standard. We are unable to fix this and all other DSP related problems because we have no PA1688 DSP developer now.
