LM6212 LCD monitor or TM7112 touch monitor if there is no base mount 2 nd
LCD display. This port supports either mirror mode (identical image) or
extended mode dual display function for WinXP. To support the DC power to
these Posiflex monitor, use the DC adaptor to connect into the monitor (for
TM-4115 / TM-7112) or its VGA cable (for LM-6212) or use Posiflex VGA +
power cable and set an internal jumper in KS main unit to 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.
SERIAL PORTS – COM1/2/3/4
In KS-6615/6617/7315/7317 system, there are 4 serial ports available.
All can supply a +5 V DC through pin 9 after proper jumper setting change.
All ports are standard RS232 serial ports as status at delivery.
When a serial Modem is to be used in KS system, it is most
recommended to use any COM port other than the COM1 port for this purpose.
In this way any hardware resource conflict is eliminated and the MODEM ring
up function can be supported.

speakers with maximum audio power of 2 W at lower corners of the main unit
