I wonder if somebody can give me a clue how to control a Theta Casablanca III with TSU-9600 paired with RFX-9600 via RS-232.
The document from the manufacturer that I have read is :
[Link: thetadigital.com]

I have try the database from Kevin Magee, but still no response from my Theta Casablanca III.

I made the RS-232 cable with straight pin connection but left pin 8 and 9 without connection, could this be the problem?

I try the RS-232 port #4 and do both straight and crossed between pin 2 (send) and 3 (receive) but I am afraid that controlling Theta is not as simple as I expect :-p

I looked at the diagram. Dis you tie together the pins as stated in the theta manual? If not it will not work. See my post on a similar thread for more detail.

Hi Barry,

Meaning that I have to short pin 1,4 and 6 on each side?

I have not done this since the document say that "the RS-232 cable must be a regular RS-232 or mouse extender cable that are wired pin to pin".

So do you think that it will be OK if I short those pins together?

Thanks.

The shorting is done only on the theta side. The RFX does not even have wires attached to those pins on it side. The statement about the cable is that it is to be wired straight through on pins 2,3,5. Wiring all the other pins straight through will not matter as the RFX will not look at them.

For undertsanding what the pins are: DCD (1) Which is Data Carrier detected, an input to the Theta that when asserted states that there is data available for the Theta, DTR(4) which is Data Terminal Ready, an output of the theta that is always asserted and means that the Theta is ready to communicate and lastly DSR(6) an input to the Theta and means that the comm line is ready and working. By tying those three pins together you are taking the asserted signal on pin 4 and using it as a voltage source to assert the two signals on pins 1 and 6. This in effect formally tells the theta that it can communicate at any time in full duplex mode. There is one other signal CTS (Clear to Send) but the document states that the Theta disregards this (no flow control)

If you really want to understand what is going on go to my web site (see my profile) and pull the document called Pronto PRO Communications. Understanding it is not a requirement for making it work.

Do you have the setting correct in your Casablanca? Baud rate, stop bit, no parity. It's likely something very simple. My file works well with the Casablanca. My file setting are 115200 baud rate, 8 bits, no parity, stop bit 1. Change the setting in your Casablanca if you have not done so.
