Vector Interface Box Reference Manual 6
1.4 Pin-Outs
There are two serial port DB9 connections on the Vector Interface Box. The one marked
‘Primary A RS-232’ is used to communicate with the Primary (or Master) antenna’s main port,
while ‘’Secondary A RS-232’ is for use with the Secondary (or Slave) antenna’s main port.
The following table details the pin-out of the serial ports of the Vector Interface Box. Below is
a figure of the DB9 socket numbering. If you are unable to communicate via the serial ports, this
may be due to an incorrect connection from the Vector to the terminal Strip. Please refer to
Table 1-1 and ensure all wires from the Vector Power/Data cable are properly connected.
