3 Power
The TS-3200 requires
regulated
5VDC at 375mA (typical). A quick release screw-down terminal block
for the 5V power and power GND connections is provided for easy connection to an external power
supply.
When power is first supplied to the TS-3200, the board mounted LED is immediately turned on under
hardware control. Once the processor begins execution, the LED is turned off. The LED then turns on
then off to provide a characteristic blink during execution of POST. If the LED does not turn on at all,
the most likely problem is the power supply. Check that the +5V and GND connections are not
reversed. A diode protects the board against damage in such a situation, but it will not run.
Please note that supply voltages over 6VDC may damage the TS-3200. Be sure to use a
regulated
5VDC power supply.
4 Memory
4.1 SDRAM
The TS-3200 has a total of 8 Megabytes of high-speed SDRAM providing 640 KB of base memory, 7
Megabyte of extended memory, and 128 KB of shadow RAM for the BIOS and DOS-ROM. This is
identical to a standard PC memory map. The TS-3200 can be ordered with 16MB or 32MB of SDRAM,
but it is not field upgradeable.
If using DOS, then the 7 Megabyte of extended memory can be used as a RAM disk by adding the
vdisk.sys
device driver. The RAM disk is accessible as drive C: if the DiskOnChip 2000 Flash disk is
not
installed, drive D: if it
is
. The size of the disk can be reduced to provide extended memory for an
application (or simply removed entirely) by editing the CONFIG.SYS file in the root directory of drive A:.
Please see the
BIOS/DOS User's Manual
for further information on vdisk.sys.
4.2 Flash
There is a total of 1 MB of Flash memory on the TS-3200. The top 128 KB of Flash are reserved for
the BIOS and DOS-ROM. During POST, they are copied from Flash into DRAM at addresses E0000h
through FFFFFh for improved performance (a standard technique known as BIOS Shadowing). The
remainder of the Flash memory (896 KB) is used by a SSD (solid state disk) appearing as drive A. The
SSD is fully supported by the BIOS as an INT 13h drive.
The flash memory can be populated using a 2 MB chip instead of a 1 MB. This option provides
additional storage space and is less expensive than adding an 8 MB DiskOnChip module.
The physical Flash memory is accessed by the BIOS in protected mode at memory address 52M.
The Flash memory is guaranteed capable of a minimum of 100,000 write/erase cycles. This means
that if you completely erase and rewrite the SSD drive 10 times a day you have over 27 years before
any problems would occur. Reading the SSD produces no wear at all.
The flash drive is
read-only
when JP3 is not installed. See Section 12 for more information.
