Serial Cable Installation

In order to maintain the IP-54 protection level, please use a certified
IP-54 connector or the one provided by Agilent.
The supplied serial cable must be installed when the Turbo-V 750/850
TwisTorr Pumping System has to be controlled by means of a remote
com-puter.
The cable is installed fixing the 9 pin D-type con-nector into the J2
serial connector.
Procedure to Connect the Serial and I/0 Ports to an
External Cable
In the following picture, it has showed the right procedure to connect
a cable to the I/O or to the serial port.
A shielded cable of 30 m maximum length has to be utilized for both
serial and I/O port connection. Remove the metallic enclosure on
both the ends of the cable (picture b) and after it is necessary to
connect the wires to the single pins like showed in the picture c.
Take care to have a good contact between the metallic case and the external
NOTE
shield of the wire. Moreover, this operation has to be done at least on the
controller side.
In this way, you will be sure to reduce the influence of the external
noise and to accomplish the EMC requests. In picture d is showed the
cable assembled.
