RS-232C(Optional)
The logic analyzer interfaces with RS-232C communication lines through a standard
25 pin D connector. The logic analyzer is compatible with RS-232C protocol. When a
hardwire handshake method is used, the Data Terminal Ready (DTR) line, pin 20 on
the connector, is used to signal if space is available for more data in the logical I/O
buffer. Pin outs of the RS-232C connectors are listed in the following table.
