Digi Connect IT 4/Mini & Digi Connect IT 16/48 - RJ45 RS232 Serial Pinout Differences

Note:  Digi Connect IT serial ports and serial cable length of run:
The RS232 standard requires support for baud rates up to 9600 baud on shielded multicore cable up to 50 feet (15 meters) long. For the 4, the use of standard CAT 5 cables enables serial communication at all baud rates up to 50 feet. CAT5 unshielded twisted pair cable lengths much longer than 50 feet have been verified at 9600 baud but are non-standard and are not guaranteed.
 

Digi Connect IT Mini & Digi Connect IT 4 use the same 8-wire RJ45 RS232 pinout
