I am trying to analyze some serial data. I have a async to sync convertor from a German company that has inputs and outputs like this :-
Asynchronus Side
9pin D-Sub female
Connect this to the PC-COM port using a 1:1 cable
Hardware-Handshake needed
1 DCD output
2 RxD outuput
3 TxD input
4 DTR input
5 GND
6 DSR output
7 RTS input
8 CTS output
9 RI output
Synchronus Modem Side
25pin D-Sub male
2 TxD output
3 RxD output
4 RTS output
5 CTS input
6 DSR input
7 GND
8 DCD input
12 AuxIn0 input low/open=ByteSync Preamble; connected with ‘high’=BitExact CTS/DCD assumed
13 AuxIn1 input PC side baud rate: low/open=115200N81; connected with ‘high’=19200N81
15 TxClk input low-high à change bit TxD
16 AuxIn2 input connected with ‘high’=DTR is sending a 61440Hz synchronous clock
17 RxClk input high-low à sample RxD
20 DTR output
22 3.3V output ‘high’ for direct connection to pins AuxIn0, AuxIn1 and/or AuxIn2
This information is taken directly from the spec sheet so I don’t possibly know what it means.
I am trying to ensure that the synchronous output is the same as the asynchronous input but don’t know which analyzer to use. I would also like to test the other way around ( synchronous to asynchronous).
I have a Logic Pro 16 but do not know where to start, how to connect it and where to start capturing data. Any help would be grateful.
