gspence Posted February 28, 2013 Posted February 28, 2013 Does anyone have this RJ45 to DB9 cable that came with the 2413S PLM? I'm attempting to connect this PLM directly to my computer and can't locate the cable. I can't locate the pinout diagram to map the RJ45 pins to a DB9. The Quickstart guide shows the connections for Tx and Rx, but it doesn't specify pin numbers for TTL In/Out or Ground. I'm assuming ground is standard, but I can't find a specification for the TTL connections. Are these even necessary when connected to a standard serial port (DB9)? Thanks! Greg
LeeG Posted February 28, 2013 Posted February 28, 2013 That cable was/is packed with the PLM itself. It is inside one of the folds of the white cardboard packing material that holds the PLM in place inside its box.
LeeG Posted February 28, 2013 Posted February 28, 2013 That is a 3 conductor cable with pins 1,7,8 used on the RJ45 end.
Brian H Posted February 28, 2013 Posted February 28, 2013 On a DB9 serial cable common is pin 5. The TTL signals are not in the provided cable and are not any RS232 signal.
