supply the required power through the VGA connector for LM-6212. Do not
connect other monitor to this port before the power in this port is disabled.
CUSTOMER DISPLAY
Please follow the instructions on the manual that comes along with
the customer display PD-2501 or PD-2602 when it is installed.
SERIAL PORTS
The serial ports in Jiva system can supply a +5 V DC through pin 9
after proper jumper setting change. However, they are set to standard RS232
serial ports as status at delivery.
COM1 serial port must always be occupied by a suitable serial device
or COM1 terminator (as supplied). If this port is left vacant or connected with
something like a mouse the cash drawer control and the power management
function may fail to work correctly. For serial Modem application, please use
COM2/3/4 port to minimize any hardware resource conflict. For models with
Infra Red type touch, the COM4 port is occupied and covered. Please never
try to open the cover. Otherwise the product warranty is voided.
SOUND PORTS
The audio port in Jiva system supports a Microphone in and a stereo
line out jacks. There is a single channel internal audio amplifier in the output
port to drive the 2 slim type speakers installed in the I/O area inside cable
cover with 1 W audio power (For slim base models this item is an option).
Should the application demand for higher audio power, please first ask your
dealer to disable the internal audio amplifier and connect the amplifier or a pair
of speakers with booster to this port. Please note that this modification should
be handled by a qualified technical person only.
FAN CONTROL
In the preloaded OS for Jiva system, there is an embedded function
that can be enabled and keep monitoring the interior temperature and the fan
revolution rate and regulating each required fan power to obtain maximum
ventilation effect with lowest possible noise. Please find it in “Posiflex Tools”
of “Program Files”. It will remain enabled even after system turning off/on
until being disabled.
On occasion of unexpected system failures, please check the airflow
condition and environment temperature of the system. Check if the fan is stuck
by something like dry grease or threads. Try to correct the situation when the
system is off and cooled down. You may power up the system again after the
system cooled down and trouble cause removed. However, if the failure
repeats, please consult your dealer for possibly fan replacement on worn out.
