How do I get the Lantronix UDS1100-IAP communicating over DNP?

If using the Lantronix serial DB25 to DB9 interface, cable part number 297218 can go from the DB9 cable to the RJ45 serial connector on a SCADAPack. In particular, a straight through cable with the TX, RX and Gnd lines is needed.

||Function||RJ45 pinout||DB9 pinout||Function|| || SCADAPack DTE Function || RJ45 pinout || DB9 pinout || DB9 DTE Function ||

|TxD|6|3|TxD| | TxD | 6 | 3 | TxD |
