When in DHCP mode, regardless of the lease duration set on the server, the DP832A requests a new IP every 5 minutes.  So it seems to be ignoring the lease duration, although this could be linked to...

Every so often the supply will drop off the network, either a reboot or a reset of the IP parameters via the front panel will fix this.  Also the display will display the LAN connected message at power up OK, than also randomly display this again from time to time.  Even with a static IP address assigned this will happen too.

I have swapped the ethernet leads, different port on the switch etc. and the problem persists.  The unit is running 1.14 but I think it did it with 1.13 too.

It's a real pain as I control the PSU via ethernet for some semi-automated testing of items and it's *really* annoying when it happens as it means I have to restart the tests.  The DP832A will complain it is under remote control, but not respond to commands or even a ping when it drops off.  You need to 'release' it using the Back key when this happens before you can talk to it again.  Even when not talking to the unit via IP and just using the front panel the unit will stop responding on the LAN side too.

Anyone else seen anything strange with the ethernet port or is this a developing issue with my DP832A?

I have been experiencing same.  Mine is a DP831, 00.01.14 Tried different cables different switch, Static IP, DHCP. (Not really sure what AutoIP is but turn it off when I use ManualIP) etc, but sometimes after time has passed it stops responding but not always.

Very annoying

Glad it not just me!
I have tried all sorts to keep the IP side going, nothing seems to work for long.  I have been looking at getting a different PSU, partly because of the IP issue and partly as I could do with a wider voltage range from time to time.

vertual:
Same problem, when device controlled by matlab trough ethernet DP832A time to time self reboot. Fixed IP.
I have one 3 years ago, with firmware 1.09.00.01 it happens maybe one time per months.
Second tool new one with latest firmware, self reboot almost 1 time per 1-2 day.
My software just in the cycle one time per second fetch current and voltage from CH1 and CH2.

Even it one time happens on my eyes, CH1 and CH2 self OFF, over 0.5 seconds disappear image on the display, over 2-3 seconds tool again ready to work. But connection with computer terminated, program stopped, output is OFF. 1-2 days of work lost.
after self reboot possible immediately restart program and enable output, but need close port and open again.

Maybe somebody know how fix it, or how to see error log from device?

Its a terrible work around but if you need to be able to get it back on the network remotely I found shut/no shut on the switchport gets it back online.


Initial tests indicates that it stays online between 6 - 17 hours.

hi,

i've noticed another thing.. but for sure i'm doing something wrong..

i have ch1 setted at 5V for a 5V logic board and ch2 at 3.3V for 3.3V logic. the 2 circuits has GND in common and a level shifter for the signal data.

what i see is that the current is measuared totally on ch1 and i have 0A on ch2...

i read about similar problem betwen ch2 and 3 but not for ch1 and ch2. it's normal this kind of readed values?

thanks
