It acts correctly to all my commands, except those when it must write something back.
I'm using 1:1 cable with usb to serial adapter.
I've used putty terminal program to connect with it and same results as using PySerial.
Device do not answer even command *IDN?
Measurement values comes to device screen, but nothing is sent to the serial, at least putty can't read anything, while i was testing.
Hope some1 has idea what's going on with my device.
i try measure 9V battery on 10VDC range and slow mode.
Code i'm trying to use:
Code: Select all
*rst; *CLS wait 1.5 s :system:azero:state off wait 1.5 s :volt:dc:nplc 10; :volt:dc:dig 7 wait 1.5 s :VOLT:DC:RANGe:UPPer 10 wait 1.5 s :volt:dc:average:state off wait 1.5 s :trigger:delay 0.0 wait 1.5 s :read?
most of the code is from the forum.
Input is 220V, 50Hz

p.s. i've tried auto modes and config it by using examples, nothing works.
Tried different rates, nplc, dig values, baud, flow, terminator options.
Changed USB to serial adapters and used different usb ports.
Tried front and back connectors of the 2000.
