Hi Andrew,
You can most probably use StreamDevice to talk to the device. I did the
same for the Pfeiffer MaxiGauge.
The document you mentioned says:
3.18. Operations Via Serial Interface RS 485
The group address of the TC 600 is 960 of the TC 100/TCK 100
is 950. All units connected to the bus must have differing serial
interface addresses [P:797]. The connection of an RS 232
(for example, a PC) is possible via Level Converter
PM 051 054-X. The description of the data communication
(PFEIFFER VACUUM protocol) can be found in Operating
Instructions PM 800 488 BN.
So look at "Operating Instructions PM 800 488 BN" for the commands.
Maybe they are similar to the Pfeiffer MaxiGauge. This is my protocol file:
InTerminator = CR LF;
# no outTerminator because of unterminated ENQ
replytimeout = 1000;
readtimeout = 100;
#address = ""; # for RS232
address = ESC "0\$1"; # for RS485
@mismatch { out ETX; }
debug {
out $address "%s" CR;
in ACK;
out ENQ;
in "%39c";
}
pressure {
out $address "PR\$2" CR;
in ACK;
out ENQ;
in "%(\$3:STATUS.VAL)d,%f";
}
I successfully tried a USB/RS485 converter, a RS232/RS485 converter and
a Network/RS485 converter to connect to the device.
Best regards,
Dirk

Hi all,
We have a Pfeiffer Turbo Pump, model TSH071E, and wish to
communicate with it.
Has anyone developed a device driver and/or stream device protocol
files that could be
used, or a similar driver/protocol files that could be used a starting
point?
Also I found:
_http://mmrc.caltech.edu/Vacuum/Pfeiffer%20Turbo/DCU%20Operatioins.pdf_
while doing research. Can anyone confirm (or deny) that this is the
correct protocol
specification to use?
