genesys

[niello89]

hello, I'm trying to use the genesys lambda 750W generator in remote mode.

I have installed labview 8.6 in a PC with RS232 port. Because the power source only have the ethernet port, I have bought a RJ45 to RS232 cable.

This cable is a non-original one. 

The problem is that when I connect the genesys lambda with the PC, when I start the GEN Serial GUI.exe and select the address, next I sent ADR 06 to the power source, it doesn't respond OK. In the windows appear a time out error.

What can I do? I have already verified the rear switches and they are all in down position, like default setting.

when I do the test with NI-Measurement&Automation appear:

Sheet --> Basic I/O - viWrite

Buffer --> *IDN?\r

Return Count --> 6

Return Status --> 0

Sheet --> Basic I/O - viRead

Count --> 1024

Return Count --> 0

Return Status --> xBFFF0015

Please help me

What were you thinking?

Ethernet uses TCP/IP protocol. Your power supply communicates vie TCP/IP (Although, the device can be purchased with a USB option.)  A PCs serial COM port uses RS232.  Simply creating a PHY layer link will not "magically" convert RS232 to TCP/IP.

Randomly connecting cables like you have done is a good way to blow up equipment. You seem to not understand anything about either Ethernet or RS-232.

I have read the manual and the cable was indicated to the accessories.

Do you have ever use a genesys lambda with labview? Do you know what can I do for use it?

[Dennis_Knutson]

I don't believe for a single minute that the manual said to connect the instrument's Ethernet port to an RS-232 port on your computer. To connect to the Ethernet port of the power supply you would obviously need an Ethernet port on the pc. You must have a least one of those since you are using the Internet to ask this question. Add another nic to the pc, connect the instrument to a switch/hub, disconnect , your current connection and connect direct to the instrument, etc.

this is the link of the manual:

in my opinion it is clear that the connection between PC and tdk lambda can be made with that cable. 

I'd like to know if I forgot anything causes me that problem with the timeout error 

[Dennis_Knutson]

You mistakenly identified the RS232/RS485 port on the back as Ethernet. That wasted mine and Jeff's time. Thanks for that.

I have no idea what sort of custom cable you created or whether it is correct. Did you buy it from TDK/Lamba? A timeout on a serial device can be caused by wrong com parameters, wrong type of cable, wrong command, wrong terminator.

Use this driver

It was developed to work with the serial interface to the unit although it was tested with the onboard USB-RS-232 adapter option.  It should work for the serial port.

make sure the device is configured to use serial communication.

Check the pinout of your cable it might need to be straight through (Null) or crossover.

If you peek into the readme on that driver you might just see a familliar name in the revision history.  (the previous one was horrid I cleaned up the worst offences but won't claim its "pretty")

[niello89]

thanks you. I'll try to install that drivers the next time I go in lab. But I have the 2009 version of labview. 

I have verified the address, the baud-rate, the switches on the rear of the instrument, but it appears all ok.

I have verified the COM in the PC, too..but it doesn't talk with the tdk lambda. when I send "ADR 06" to the power source it should say "OK", but I read only

ADR 06

ADR 06

and the timeout error

I'm having the same problem. Rs232 to db9 connector for the TDK lambda gen 150-10. I have the cable connected to com1 but when I go to hyper terminal no responses come from the power supply when j type ADR 06. I know I have the baud rate, data bits etc right but it won't work
Any suggestions?
