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:
Code:
viznet.client.connect('192.168.10.1')
the command returns false
I appreciate any suggestions.
Code:
# 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.changeMostRecentSampleValueDeliveryEnabled("calc",0,True)
except Exception:
useAcqServer = False
return
useAcqServer = True
