on the VDM100. lt is recommended that this connection be secured to the jack
screws on either side of the DB-15 plug on the VDM100. Note that if the DC
power supplied by the user is on, the VDM100 electronics will power up at this
point. lt is recommended that Pin 4 and Pin 14 of the DB-15 not be grounded
at this point to keep the VDM100 in the idle state.
4. Connect the AC power to the power entry module.
5. Switch the ON/OFF switch on the power entry module to the "On" or "l"
position.
The installation process for normal VDM100 operation is now complete.
Section 2.11 RS485 Communication discusses making use of the optional
serial communication connections for use with the Brooks GUI. If that is not
required, proceed to Section 3 VDM Operation.
Items 2 and 3 in Section 1.6 Bottom View, earlier in this manual, describe
two connections that allow a user access, via serial communication, to the
diagnostic information available from the VDM100. The VDM100 can also
be operated through these connections. The GUI installed on a PC acts as
the interface to perform these operations. For more information on the use
of the GUl, see Section 4.0 Operation of the Brooks Graphical User
lnterface (GUl) for VDM100 later in this manual and/or the Graphical User
lnterface (GUl) manual available with the purchase of the GUl.
The RS-485 Diagnostic Port (ltem 2 in Section 1.6 Bottom View) can be
used with the purchase of a serial communications package from Brooks.
This package connects a PC's 9-Pin serial communications port (com port)
to the 2.5mm Mini-Jack port on the VDM100. Contact Brooks for further
information about purchasing this item along with the GUl.
