#86231 - End of wrong stick! Responding to: ???'s previous message |
Stephen Harris said:
The interface is one that i am using to program the 8051 and thats it the connections are 2,3 and 5 (Tx, Rx and GND). There you go again - "2,3 and 5" are meaningless without knowing to what they refer! I assume you are talking about an RS232 interface on a 9-way D-type connector? But that wasn't the question. The question was, what type of serial interface does your mysterious RF module require?: All i am asking is if i can intercept the data on these pins before the MAX232 chip as TTL levels? Well, that certainly wasn't your original question, was it? Yes, the signals between the 8031's pins and the MAX232 pins will be logic levels (whether they are specifically "TTL levels" will be stated in the Data Sheets). But whether these signals are of any use to your Mystery Module remains unknown! |
