Connecting External Equipment
To ensure best performance from the Showmaster Go, and compliance with relevant EMC
regulations, this equipment should only be used with high-quality shielded data and signal cables.
Only equipment and accessories approved to IEC 60950-1 and SELV circuits may be connected to
the unit. All equipment and accessories shall comply to the relevant standard for the unit’s port to
which it is connected.
Connecting the GPIO
Showmaster Go units have opto-isolated GPIO connectors. These operate between 3.0 and
5.0 VDC, 35 and 100 mA. Take care not to exceed these values.
Environment
General
Showmaster Go is intended for use in a commercial (not domestic) environment and should be
operated in a clean, dust free area (e.g. a server room).
The unit is intended for operation in benign environments; that is, not subject to corrosive or
explosive atmospheres, moisture or flammable gases. The unit is non-protected against ingress of
liquid (IPx0). The unit is not designed to be subject to excessive mechanical shock or vibration. For
environments with some movement and vibration, an anti-shock frame mount is available for single
units.
Only used at altitude
not exceeding 2000 m
Only used in not-tropical
climate regions
Thermal
Do not block any of the unit’s air vents and ensure the ambient temperature around the unit is
compatible with the environmental characteristics stated on the back page of this manual.
Particularly when mounted in a rack cabinet with front or rear doors the ambient temperature
around the unit may be higher than the ambient room temperature.
Showmaster Go can be mounted vertically using the optional VESA mounting plate, but
care must be taken that hot air from the rear panel is not drawn back in at the front. Do
not mount with the front panel uppermost.
Electrical
Before connecting mains power to the unit’s power supply unit (PSU), ensure the electricity supply
is compatible with the electrical ratings shown here and on the power supply product label.
The power supply unit is connected to, and disconnected from, the mains
supply with an IEC 60320 power connector.
The low voltage output is connected to the labelled rear socket of the unit, where the lead can be
secured to the chassis with the clip provided.
Only use the 19 VDC power supply unit that is supplied by Medialon with the unit. Failure to do so
may damage the Showmaster Go and invalidate any warranty.
Maintenance
Air Filter
A user-serviceable air filter is located on the unit’s front panel. It is important to remove and clean
or replace the filter periodically to avoid overheating.
Showmaster Go units are supplied with one spare filter pad, others can be provided by your supplier.
Showmaster Go should not be run without filters, since accumulations of dust inside the unit can
affect performance.
Cleaning
External casing and the front panel should be carefully wiped with a soft cloth and antistatic
solution.
Showmaster Go internal maintenance
Showmaster Go contains no user-serviceable parts. For CMOS battery replacement please contact
your supplier for further instructions.
Warning
: Do not operate the unit with any covers removed as the air flow through the
unit may be compromised leading to overheating.
Any alterations to the product’s specification, including additional/alternative components, BIOS
changes, overclocking, etc., may invalidate the warranty or impact the unit’s performance.
Additionally, such changes or modifications could cause equipment no longer to comply with the
relevant EMC regulations, and void the user’s authority to operate the equipment. If in doubt,
please contact your supplier.
Electrostatic discharge (ESD)
When handling electronic assemblies, take precautions to avoid electrostatic discharge (ESD)
causing damage. Precautions should include the wearing of an ESD protective wrist strap and
using antistatic bags for electronic assemblies when not installed inside a unit.
