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.
