Title: Sharp Serial Connector
Post by: woverin on November 24, 2004, 07:32:45 am

Anyone know where can I buy sharp serial connector cheaply?
I wanna do my own DIY cable. Interfacing with other hardware.

I also am interested in this. This was discussed before but i think the price was $30, plus a lot of shipping to Europe for me....   Thinking of either adding to my USB iPDA socket  or getting a serial cable...

FYI
the sharp serial connector is made by HOSHIDEN
model: TCX3106E-010100

You can buy the connectors individually from http://www.fivestarassoc.com/Z/index.html (http://www.fivestarassoc.com/Z/index.html) for $8 each or a 5-pack for $35.

I ordered one from them awhile back.  It's been holding up nicely on my GPS.

Shdwdrgn,

Could you give me some pointers on how....

1. you wired up the Zaurus Connector to say a 9-pin D-type

2. what you had to do on the Zaurus to free-up (have access to) to /dev/ttyS0

3. what test software you used eg. minicom and settings

I have a shirtpocket 860 with sharp ROM

Thanks.

1) See the wiki at http://www.zaurususergroup.com/modules.php...name=SerialPort (http://www.zaurususergroup.com/modules.php?op=modload&name=phpWiki&file=index&pagename=SerialPort)
TONS of useful info there, including my own additions on wiring the connector for the digitraveller GPS.

2) Edit /etc/inittab.  You will likely find a line similar to this:
S:2345:respawn:/sbin/getty 115200 ttyS0
(NOTE the ttyS0 - that's your serial port)
Comment out the line by inserting a # at the beginning.  Then issue the command "init q" or reboot your Z.  Serial port is now available for use by devices.

3)  Also located in the wiki... issue the following commands:
stty 4800 -F /dev/ttyS0
cat /dev/ttyS0
You should see all of the information passing over the serial port.  Hit Ctrl-C to stop the data stream.

Thanks for the pointers.
As I have a different hardware (C860) and software (Sharp ROM) from yourself I am having some difficulties achieving the right setup to enable /dev/ttyS0. For example my version of stty does not have the -F option. I shall play around and see how far I get.

Hi,

Can someone please tell me the thresholds of the inputs for the sharp c860 serial port? Is 0 and 3.3volts sufficient for low and high? Will rs232 levels damage it?

Hi,
I have now got my serial connector working. Wasn't using the correct pin numbering.

Attached is a pdf that you may find useful.
