Rs-232

Archiver

I need to run a BS2 at 57600,8,n,1 noninverted through a line
driver is this possible and what is the baudmode value I would
use?
thanks larry

Hi,

The formula for the BS2 and BS2E is Int(1,000,000/baudrate) - 20
For 57600 baud you get -3 (!!!) so it cannot be done with a BS2.and BS2E.

The formula for the BS2SX and BS2P is Int(2,500,000/baudrate) - 20
For 57600 baud you get 23 so it is poosible with a BS2SX or BS2P.
but probably only for simple variables (no modifiers).

Regards peter

I'd like to incorporate a wireless RS-232 connection into a project - I was
thinking of using the linx ES series reciever and transmitter, because of
the high data rate and range. The data out from the reciever from what i
understand is 5 volts at logic high, does this mean i need to use an RS-232
reciever to adjust the signal before sending it to the BS2p SIN pin?

+5V is transistor-transistor logic (TTL), that should be fine with
the basic stamp.

i thought standard serial protocol was logic high at 0 volts though?

I have a bs2p. I want to connect it to a sensor that communicates via
RS-232. I am wondering if it is possible to interface an RS-232
peripheral to a stamp in this manner.

Any advice would be greatly appreciated.

Thanks,

J. Manning

just couple into any pin 0-15 via a 220 ohm resistor and set up that pin
unsing the SERIN command protocol on the stamp.
