3. DLA Drivers
The DLA has software 'drivers' (i.e. programs which handle
communications) programmed into the unit. There are
matching drivers that must also be resident on you PC.
The update of both these sets of drivers is handled by JCB
Service Master. Please refer to the applicable supporting
literature.
4. PC Power Management
Some laptops' Power Management software can disrupt the
COM ports.
This problem occurs with many other software applications
and is not unique to JCB Service Master applications. The
following advice is worth bearing in mind.
If the user experiences communications problems with a
ShiftMaster ECU turn OFF the laptops' power management
software.
Problems may be;
(a)
Complete failure to establish communications with an
ECU.
(b)
A drop-out of communications (i.e. connects to the
ECU and after a while the link fails).
(c)
Intermittent failure (i.e. seems to disconnect and re-
connect at random intervals).
Item (a) is probably the most common.
To turn OFF the laptops power management open Windows
Control Panel (Start > Settings > Control Panel). There will
normally be an icon to run that particular laptops' power
management software. Turn OFF the power management,
close the tool and then close the control panel.
These power management tools are specific to the laptop.
Some may require the PC to be re-booted before the
changes take effect.

5. IR Drivers
Many Laptop PCs have a built in InfraRed (IR)
communications port. There is likely to be some resident
software to control this port. If this type of port is present,
but never used, then try disabling the driver;
System Properties > Device Manager > Ports > ..... (infrared)
6. Modem Drivers
Check that only the correct modems are installed on the
machine.
Experience has shown that multi-user PCs often contain
many modems, perhaps installed for use other than in the
office.
Disable any unused modems.
There has been no experience of correctly installed internal
modems or PCMCIA cards (modem or network) causing
significant problems.
7. Windows XP & Windows NT
Please note the ShiftMaster Diagnostics software is NOT
designed to run on Windows NT. In addition JCB can not
guarantee that this software will be fully functional with the
latest versions of Windows (e.g. WindowsXP) although JCB
are continually developing support for different operating
systems.
8. Further Assistance
If a communication problem persists, then the following
contacts may be able to provide further assistance;
a).
If applicable, try seeking assistance from your
Computer Systems Engineer/Technician.
b).
The first port of call outside your company should be
the laptop machine dealer or agent.
c).
Your next enquiries should be with the laptop machine
OEM (Original Equipmemt Manufacturer). If the OEM is
unable to assist they will make the relevant enquires on
your behalf.
If you continue to have a communications problem, note
the applicable laptop make and model. Contact JCB
Service so that further investigations can be made..
For all enquiries about the ShiftMaster Diagnostics tool
please follow your normal channels of enquiry. This ensures
that useful information can filter through to JCB Service
personnel at all levels.
