Put the following commands in your startup script, right after the asynSetTraceIOMask command you already have.
asynSetTraceMask("song",0,9)
Then you will see exactly what characters are sent and received over the serial port.
You should also load an asyn record on that port. Then you can quickly type commands in the medm or other GUI and look at the response. You need to know at least one valid command that you can send to the device, so read the manual to learn that. Also try to figure out what baud rate the device is set for. With the asyn record you can change the baud rate, parity, stop bits, etc. Once you get the asyn record to show the correct response then hopefully the device support will work.

Thank you for the reply.
A. Please send the entire output when the IOC starts up, and then begins giving the errors you showed.

I have a one more question.
When I changed the baud from 32600 to 9600,
It shows different error message.
As I know, the default value of baud is 9600.
Should I fix this baud number for the tpg261 model?
linux(Ubuntu12.04 LTS) computer and TPG261 connection is not, Should any device be connected?
B. I don't know what you mean by "TPG261 connection is not". Do you mean that the gauge is not connected to the computer? If so, then the error messages you are seeing are probably normal.
- I had mistake. you don't need to take care about this.
Thanks

Subject: TPG261 : "message too small=0" for EPICS
Dear all,
I am just starting to learn the EPICS.
In order to monitoring vacuum level of my chamber, I used pfeiffer TPG216 single gauge.
I installed "baseR-3.14.12.1" and "synApps_5.6".
Directory is following
$HOME(or any directory where you want)/EPICS/base
$HOME(or any directory where you want)/EPICS/modules/synApps_5_6/support/ip-2-13
$HOME(or any directory where you want)/EPICS/modules/synApps_5_6/support/asyn-4-18
$HOME(or any directory where you want)/EPICS/modules/synApps_5_6/support/ipac-2-11
$HOME(or any directory where you want)/EPICS/modules/synApps_5_6/support/seq-2-1-3
and so on.
I would like to use "ip" which have db and sorce codes for TPG261 model.
when I execute ipApp with st.cmd, what only I can get is following messages.

2013/08/22 21:17:45.779 devTPG261::devTPG261Callback Cmd Vacuum:tpg261:SP2S message too small=0
Could you help me with this problem ?
linux(Ubuntu12.04 LTS) computer and TPG261 connection is not, Should any device be connected?
Thanks
