Making Additional Connections
Make the following connections to the standard input/output connectors on the ptf 3207A rear panel:
• The ANTENNA connector to a GNS antenna cable.
• The ENET Ethernet port (RJ-45) to an Ethernet network using Cat 5 cable. This
connection is needed to manage the ptf 3207A remotely, or to use the optional NTP function.
• The SERIAL I/O connector to a PC using an RS-232 null modem cable.
• J1 thru J12 as needed.

NOTE: There are many different configurations that necessarily require different input/output
connections. In some cases many of the connections will be blank. For each specific instrument
connections are detailed on a label above the input/output connectors. Where this label differs from
the connections outlined above, the label always takes precedence.
