The only other pins you need are RTS and CTS but this really depends on the
speed of your RS232 connection. I am running 57600bps on an Rabbit 5000
board to a modem and it works just perfectly without the RTS and CTS
handshake lines.

If you do connect RTS and CTS you have to define which pins it uses. These
are not fixed and you are free to use what you want although I am not
familiar with the BL2100 and it may already have these pins allocated.

If you run the serial link at 19200 you might get away without the need to
use RTS and CTS.

I think the 15 pin connector is similar to the Wavecom modems in that some
pins are used for speaker and microphone input. Just connect the RS232 level
pins to your BL2100 and it should all work just fine. The AT command AT&K0
will disable the hardware handshaking if you find that it causes the modem
to stop sending to the BL2100.

Good luck.

Subject: {Disarmed} [rabbit-semi] Multitech Modem Interfacing with rabbit
BL2100 Board

Hi all,

I have a Multitech "Multimodm GPRS Wireless Modem" with a 15-pin Serial Like
Interface.

I want to interface it with a Rabbit Bl2100 Board's Serial Port and test it
some DC9.62 Sample. (i havent got RJ-45 connector on the board)

I am a bit confused about the wiring and interfacing of the "15-pin Serial
like interface" to "Rabbit's BL2100 Serial Port C".

Besides connecting RXC and TXC to TD and RD and GND pins of the Serial ,
what other things i need to do.

If someone could tell what pins are to be used , which pin correspond to
which signal Name like CD, TD, RD,DTR, DSR etc of the Serial Port of the
Modem then it will help me a lot...

Also besides the 3-pins connectivity (RXC, TXC, GND) what other pins i need
to short or connect or something else that i need to do for the rest of the
free incoming lines from Seral port of the wireless Modem.

Any help in this regard is highly appreciated.

Thanks

AM.

Thanks a lot for this information. I googled your provided info and found out this ...
 
http://coderstalk.blogspot.com/2008/12/3-pin-serial-connection-for-wavecom-gsm.html
 
Which makes me think that i have been connecting the pins totally incorrectly.
 
I have three pins on bl2100, RXC,TXC and GND for Serial Port C.
 
I have been shorting RTS and CTS together and DTR,DSR and CD together so that the modem should have been always ready to send and receive data but since the pins were incorrectly chosen so everything was going wrong.
 
The above link says that :
 
Pin Description
1   DCD (Data Carrier Detect)
2   TXD (Transmit Data)
3   Reserved
4   MICROPHONE (+)
5   MICROPHONE (-)
6   RXD (Receive Data)
7   DSR (Data Set Ready)
8   DTR (Data Terminal Ready)
9   GND(Signal Ground)
10  SPEAKER (+)
11  CTS (Clear To Send)
12  RTS (Request To Send)
13  RI (Ring Indicator)
14  RESET
15  SPEAKER (-)

I guess i need to connect the TXD(2), RXD(6) and GND (9) of the 15-pin serial modem to RXC,TXC and GND of BL2100 respectively.
 
 
 
1. Do i need to short pins RTS and CTS?
 
 
2. Do i need to short pins DTR, DSR, CD?
 
 
 
I saw somewhere that shorting is needed for making a Serial link between modems, correct me if i am wrong.

Thanks

13  RI (Ring Indicator)

I guess i need to
connect the TXD(2), RXD(6) and GND (9) of the 15-pin serial modem to RXC,TXC

2. Do i need to

I saw somewhere
