Connections to the field are made via the upper DB25 connector on the rear of the 10457 Series Card Rack assembly. This connector can be utilized by a direct connection of a DB25 cable to the field equipment, a DB25 cable to a DIN rail-mounted terminal block adapter, or with the use of a DB25-to-RJ45 connector adapter. The pinout definition for the DB25 connection is shown is the table below.

Included with the VNA are two DB25-to-RJ45 connector adapters. The 21246-014 Connector Adapter brings the transmit pair to the RJ45 pins 1 and 2 and the receive pair to pins 4 and 5. The 21246-008 Connector Adapter brings the transmit pair to the RJ45 pins 4 and 5 and the receive pair to pins 1 and 2. These adapters permit the use of non-crossover Ethernet cables for the connections to field equipment utilizing these same pins on an RJ45 connector.

Cabling to the field equipment should be a twisted pair design.
