Missing HI

We have seen a few cases where the HI output of the JSD-60 goes silent. In these cases, we've found that a gain setting
in the HI chain in the DSP somehow becomes corrupted and set to 0. When configuration is saved, this corrupt value is 
saved and then restored to the DSP on the next power cycle. The GUI does not provide access to this gain setting, so
the following command sequence is suggested to restore HI.

These commands can be executed in the Terminal window under the Diagnostics tab of the JSD-60 GUI when connected to the
JSD-60 over USB or Ethernet. They can also be executed with a terminal program such as Tera Term (get Tera Term at
http://ftp.uslinc.com/MultiProduct/ ). If using Tera Term, select TCP Service: Other, TCP Port#: 10001, and enter the
IP address of the JSD-60 in the Host field. Once Tera Term is connected to the JSD-60, select Setup - Terminal, then 
under New- Line, set Receive: CR+LF and Transmit: CR. Check Local Echo, then click OK. You should be able to hit carriage
return and get a "Bad Command" response from the JSD-60.

Once you are communicating with the JSD-60, try these commands whre [tab] is the tab key, and [cr} is the carriage return 
or enter key.:


dsprdf[tab] 0x626[cr]

	This reads the HI delay gain. It should return 1.0.

	If it is not, run this command:

dspwrf [tab]0x626[tab]1.0[cr]

	This sets the HI delay gain to 1.0.
	
	Then save to config flash and SD using these commands


jsd60.sys.save_config[cr]

jsd60.sys.save_config_sd[cr]



NOTE that all commands are entirely lower case. After running these commands, reboot the system and see if HI has been restored.
