APPLICATION GUIDES
POWER SUPPLY TO COM PORTS
On the solder side of the main board, jumpers on JP7 and JP9 determine the
+5V DC supplies to the devices connected to COM1/2 and COM3/4 separately. The
jumper on
JP3 dete12V DC supply to VGA port. Refer to the hardware
details for jumper settings. The load supplied from the Jiva KS-66 series to all USB
devices on 5 V DC is limited to be within 0.5 Ampere for each port, and power on 5 V
DC to all COM ports is limited to be within 1 Ampere. The +5V DC and the +12V DC
in HDD power connector are limited to be within 2 Ampere and 1 Ampere respectively.
The power supplied to VGA port on 12 V DC is limited to be within 1 Ampere. No
matter what, the ventilation of the environment should be much improved to
compensate the heat accumulation due to such excessive load.
CUSTOMER DISPLAY
The RS232 model rear base mount customer display PD2501 or PD2602 or
PD305 or PD-306 or PD-7622 upgrade kit can be connected to any available COM
port with an internally supplied power from the Jiva KS series set per instruction in
Hardware Detail. The USB model PD-2602U or PD-306U can be connected to any
available USB port with an internally supplied power from the KS-66 series. Please
refer to the user’s manual of customer display for detail instructions on use of PD.
Please refer to below paragraph if COM1 is selected for this usage.
COM1 APPLICATION COMMENT
Before using the port COM 1, the COM1 terminator should be removed and
stored for future use when there will be no regular RS232 device to be connected to
this port. It is definitely inadvisable to connect serial input devices like serial mouse to
COM 1 port without thorough investigation. The reason is that some input devices do
not provide standard RS232 hardware handshaking signals. In KS systems, the power
management controller shares the COM 1 port. When the system issues any command
to power management controller, the hardware handshaking signal would be in error
