yep...I thought that too...

Also, when you switch dip switch 1 on the cpu board on, it asks for a boot disk.

Gyorgy Albert:
I double checked the backpanel dipswitch. Only 1,5 and 6 are used, the others are not connected. So there is nothing else to look for here, we know the functions of these settings ( it is marked in fact on the silkscreen of the printed circuit board BLC-024514). The conditional access to the special menu is hidden somewhere else. Maybe a floppy disk with some special content is needed ( not a boot disk, since we are looking for some software option settings, and maybe the disk should contain some option files, which should be transferred in this menu to the compact flash, or flash memory in the case of analyzers without compact flash).
In one of the other topics related to the R3273, someone wrote about a serial port available on the main CPU board( some messages were listed during the ooer up). Maybe this can be used as a terminal, and there you can send special maintenance commands. However, all these should work also over GPIB.

chick0n:
I connected to the J12 connector on cpu board. Pin1 is TX, 2 maybe RX?, 3 GND, rest is GND and 5V.

I was never able to send commands.

I received some boot messages, and when the analyzer is bootet up it writes SD:/SD:/SD:/SD:/SD:/SD:/SD:/SD:/ over and over again...

When I type "shift + window + 882323 + hz", it sends "CW KEY SET" over rs232.

When I type wrong password, nothing...

In the MAINTE.X, I found Strings:

CW KEY SET
CW KEY DEL
DFM KEY is Invalid.
DFM KEY is not Delete.



Gyorgy Albert:
The serial port will be good for monitoring/debugging. Whe you try the hidden menu SHIFT + TRANSIENT +882323+Hz, does it report anything on the serial? I have to connect my analyzer to a serial port in the weekend and play a bit. Are there any other operations ( for example in the maintenance menues) reported over the serial?

chick0n:
I also found, the DSP-Board has a own Maintenance Mode. But I dont know how to access.
