ASP-15L serial
port
The ASP (Auxiliary Serial Port) consists of a D-Sub 15 pin female connec-
tor and can communicate using RS232 and RS485. Unlike the ASP it does
not carry all signals.
Before connecting in RS485, check the polarities. With some
devices the Tx+/Rx+ and Tx-/Rx- signals or the polarities are
inverted.
