UltraSatan - Frequently Asked Questions
Q: I saw a battery on the pictures on UltraSatan's PCB, what is it for?
A: UltraSatan has a battery backed up RTC, so
your ST will get a current time and date on every restart and not a year 1987.
Q: Does UltraSatan require that I already
have a ACSI to SCSI interface such as a Link II etc?
A: No, you don't need any ACSI-to-SCSI
interface. The UltraSatan is connected directly to ACSI (the same was for
SatanDisk).
Q: About the cable - is it compatible with
the cable for SatanDisk?
A: Yes, the cables for UltraSatan and
SatanDisk are the same, I used the same pinout. The pinout I use is what I
believe it would be if they (Atari inc.) would use flat cable instead of DB-19.
The wires are sorted in the same way as in the DB-19.
Q: What voltage does UltraSatan need?
A: It should be at least 7V, because there is
some voltage drop down in the device (due to rectifier). But it shouldn't be
much higher than 7V, because higher voltage will result in higher heating of the
device. So from 7V to 9V should be OK. You can use some sort of universal DC
adapter. For input voltage to regulator temperature relation look at the table
bellow.
Running from 12V (or more) not recommended. Do not try to create 7V by connecting UltraSatan between 12V and 5V line!

Input voltage [V] |
Voltage regulator temp. [° C] |
| 7 | 47 |
| 9 | 59 |
| 12 | 84 |
Q: What kind of power supply socket is in the
device? (i.e. what connector my adapter needs to have)
A: It's a 2.1 mm connector for DC power
supplies. You should get adapter with switchable connectors and try which does
fit in the UltraSatan
Q: What polarity the DC power supply
connector has to be? Where the + and - is?
A: It doesn't matter - the device has
rectifier, so both combinations are valid.
Q: Will a 2 GB card work with it?
A: I have tested UltraSatan with cards from
16MB to 8GB and they all work, so yes, the 2 GB card should work. Btw. according
to my calculations 8GB should be almost maximum that you can access using the
biggest possible partitions under TOS 2.0x, and for TOS 1.xx the maximum should
be 4 GB.
Q: Will a microSD and miniSD card work in
UltraSatan?
A: The MicroSD and MiniSD cards work with
UltraSatan, and even the SD card which can be directly pluged in the USB.
Q: I like the dual drives! Is one hot
swappable?
A: Both are hot swappable.
Q: The hot swap is functionality within Ultrasatan's logic or is it based on some kind of special software on the ST?
A: UltraSatan detects card changes and if the
card change occures, it signalizes the UNIT ATTENTION condition (SCSI sense
code). Basicly any hard disk driver for ST, which can handle that situation, can
use the hot swappable drive (the driver has to re-read FAT, etc., when the media
change occures). HDDRIVER from Uwe Seimet has this support for removable media,
I don't know if any other driver does (I don't use them).
Q: What is the transfer speed of UltraSatan?
A: The current FW version does something around 1MB/s, but it
depends on the speed of the SD/MMC card and on the TOS version of you ST. See
the benchmarks for more information.
