biopac networking

[pkhoosh]

I'm trying to modify the code in the reference manual to import biopac data channels into a common data file that Vizard records.

The first problem is that Vizard running on computer1 doesn't recognize the AcqKnowledge software running on the networked computer2 (I get an error that there's no module named acqserver). When I try to 'manually' connect to computer2 from the Vizard computer:

viznet.client.connect('192.168.10.1')


the command returns false

I appreciate any suggestions.



# test to write biopac data to file

import viz
import viznet

if viznet.client.connect('192.168.10.6'):
print 'Connected'

viz.addNetwork('192.168.10.6')
viznet.server.start(port_in=9999)

import acqserver

viz.go()

###### NETORK SETUP #######
acqServer = None
useAcqServer = False
###### NETORK SETUP #######

def useAcqServer():
# setup network connection
global acqServer, useAcqServer
try:
acqServer = acqServer.ACQServer()
acqServerList = acqServer.findAcqKnowledgeServer()

if not len(acqServerList):
useAcqServer = False
return

# set ip and port
(ip,port) = acqServerList[0]
acqServer.setAcknowledgeServerInfo(ip,port)

#work around for acqserver problems
acqServer.changeDataConnectionMethod("multiple")
acqServer.changeTransportType("udp")

acqServer.changeMostRecentSampleValueDeliveryEnabl ed("calc",0,True)

except Exception:
useAcqServer = False
return

useAcqServer = True

Do you have any virus scanners/firewalls enabled? If so, try disabling those.

I also cannot find the acqserver module, can you tell me how you fixed it?
