Psion VH10 Vehicle-Mount Computer User Manual
5.5.1 Network Access
The VH10 automatically loads the appropriate drivers to communicate with the USB-Ethernet converters.
Network Addressing
The host application uses standard TCP/IP protocol to name, locate, and communicate with a specific VH10
on the network.
If a link is established between a VH10 and a host, the application on the host and on the computer must
have a recovery mechanism in the event that the VH10 is disconnected, interrupting the link.
5.6 VH10 Mounting Accessories
Warning: Failure to install the mount correctly, or modifications to the mount, may result in
serious injury or damage to property. Contact Psion Technical Support or your Psion
representative if you have problems installing this mount. To ensure operator safety, you
must use a calibrated torque wrench and the supplied mounting hardware when fasten-
ing the computer and mount. Use of this mount in vehicles driven on public roads or
highways is prohibited. Contact Psion for further details.
Before mounting a VH10 in a vehicle, there are a number of operator safety issues that
require careful attention. When mounting a VH10 use only approved Psion mounting
hardware and mounting parts which are specific to the VH10 model purchased. An
improperly mounted VH10 or use of non-approved parts may result in one or more of the
following: operator injury, property damage, operator visibility obstruction, operator dis-
traction, and/or poor ease of egress for the operator. Psion strongly recommends that
you seek professional mounting advice from the vehicle manufacturer.
If it is necessary to mount the VH10 overhead, or in any position that could cause injury
to the operator should the unit fall, it is critical that a secondary tether or other failsafe
device be installed.
The following restrictions must be strictly enforced:
Do not use the mount and/or the VH10 as a hand-hold. Using the mount in this manner
may cause the person to fall or dislodge the mounting hardware and/or mounts.
Do not add weight or attach any other items to the mount or VH10. Additional elements
may fall causing injury, or may increase the chance of failure and/or damage in mounting
hardware and/or mounts.
Mounts used in industrial or vibration generating environments may be subjected to
fatigue, stress, and/or part wear. A periodic inspection of the mounting hardware and
mounts should be performed to ensure parts are retightened to the correct torque, free
of fractures, excessive wear, and/or other environmental damage. Any parts found to be
unsafe should be removed and replaced immediately. After inspection or replacement of
parts, readjust the mount as outlined in the pertinent sections below.
Cable routing within a vehicle cab also requires careful consideration, especially for sep-
arately connected scanners and other devices with loose cables. If you are unable to
obtain suitable advice, contact Psion for assistance. Note also that for better protection,
the equipment should be mounted inside the vehicle roll cage.
When charging the vehicle battery, the VH10 must be either disconnected from the
battery or it must be determined that the maximum allowed input voltage of the VH10 is
not exceeded.
Important: Safeguards
To avoid possible injury, this device must be properly secured when in a moving vehicle.
Keep this device away from magnetic fields.
Do not place the computer near a television or radio receiver.
Do not disassemble your VH10 computer — there are no user-serviceable parts inside.
Important: VH10f Freezer Model Installation
In order for sufficient drainage of the VH10f, the unit should sit at an angle of at least
30 degrees.
