TABLE VII. Troubleshooting Guide (software communication errors)
OBSERVATION PROBA BLE CAU SE ACTION
Appears the first time the
application was executed
1. Instrument not connected to the software
defaulted serial port
2. Communication connections not made
or instrument is not powered
1. Change serial comm port setting and hit
“Retry”
2. Check connections and instrument power
Appears intermittently
after application has
been running normally
1. Electrical noise interfering with
communications
2. Too many applications running in
windows
3. Another application is conflicting with
this comm port or IRQ
1. Change to RS-422 communications, re-
route or shield cable
2. Close other applications until problem
self corrects
3. Change to a different comm port
Completely stops
working after application
was been running
normally
1. Instrument has stopped communicating
2. Loose or damaged communication
connection
1. Check instrument power or look at
instrument display for fault status
2. Check cable adapter at back of PC or at
any other splices or at instrument
Cannot be made to work
at all with Com3 or
Com4
1. Works fine on Com1 or Com2 but does
not work on other port due to other

4.5 HARDWARE AND SOFTWARE MODIFICATIONS AND UPGRADES
Note: The workgroup setting of the identification tab in Network Neighborhood Properties must be set
to WORKGROUP which is the Windows 98 default setting. A Cat5 crossover network cable is required
for proper Ethernet network communication to the RheoVac instrument.
4.5.1 UPDATING SOFTWARE
Normally, updating the main software residing on the RheoVac Model 950 should not need to be done
by the user. However, software improvements or other factors may necessitate a user installation or
upgrade of a new main program. When this is required, instructions will be supplied.
4.5.2 REPLACING PROBES
If it is necessary to replace one of the probes, a new probe and diskette (with probe-specific calibration
data) can be ordered from Intek.
4.5.3 ADDING ADDITIONAL PROBES (maximum total probes is 3)
Each RheoVac Model 950 can communicate with up to three probes simultaneously. Additional probes
can be easily added to systems that have fewer than three probes.
Each additional probe will be shipped with a set of calibration files that must be installed on the
RheoVac instrument. Refer to drawings for mechanical and electrical connections. Specific instructions
will be supplied with the probe(s).
