IS09006A – Vector Series – NAPI80 Site Interface
PWB Installation Procedure
INFORMATION SHEET
1 INTRODUCTION
This document describes how to install the
NAPI80 Site Interface PWB in a Vector
series transmitter.
1.1 Reason for Modification
The site interface PWB is an interface
between a Vector series transmitter and
parallel monitor and control points
provided to the user. This interface allows
the user to remotely monitor and control
parts of the transmitter using their own
equipment or a Nautel ECMP (extended
control/monitor panel).
1.2 Equipment Affected
This procedure applies to Vector-LP series
NDB/DGPS transmitters (VR125, VR250,
VRD200 and VRD375) and Vector HP
NDB transmitters (VR500, VR1000 and
VR2000).
1.3 Responsibility for
Implementation of Procedure
This procedure should be carried out by
qualified station maintenance personnel
who are familiar with the Vector series
transmitter.
1.4 Scheduling
This procedure may be implemented at
the convenience of station maintenance
personnel.
1.5 Manpower Requirements
It is estimated that implementing this
modification will require 20 minutes to
complete for Vector-LP transmitters and
one hour to complete for Vector-HP
transmitters.
1.6 Special Tools/Test Equipment
Standard hand tools (screwdriver,
nutdriver, etc.) are required.
2 PRELIMINARY CHECKS
Ensure the supplied installation kit (Nautel
Part # 195-2085) includes an NAPI80 Site
Interface PWB (with 20-pin ribbon cable
assembly), and associated securing
hardware. See Table 1 for a complete
parts list.

3 INSTALLATION
Install the site interface PWB in the Vector
transmitter as follows:
NOTES
To install the site interface PWB in a
Vector-HP transmitter (see paragraph 3.1)
you be required to remove the exciter/
control assembly from the rack.
To install the site interface PWB in a
Vector-LP transmitter (see paragraph 3.2)
you will need access to the rear of the
transmitter’s front door.
Parts from the site interface installation kit
(Nautel Part # 195-2085, see Table 1) are
referenced in the following procedure.

Issue 0.2 IS09006A
For Vector-LP transmitters, see Figure
MD-1A in Section 10 in the Vector-LP
manual as an aid in locating the position
of the site interface PWB (A4).
For Vector-HP transmitters, see Figure
MD-4 in Section 10 in the Vector-HP
manual as an aid in locating the site
interface PWB (remote control/monitor)
(A2A4).
3.1 Installing NAPI80 in Vector-HP
transmitter
(a) Press RF Off on the transmitter’s front
panel. Switch off the ac power to the
transmitter.
(b) If the optional battery is used, switch
off the dc power source to transmitter.
(c) Ensure the ac and dc power sources
are “locked out” so that they cannot be
turned on during this procedure.
(d) Gain entry to the rear of the
transmitter cabinet. Ensure all cables
are clearly labeled then remove all
connections to the rear of the exciter
(See Figure MD-4 of the Vector-HP
manual).
(e) Remove the four front panel screws
securing the exciter to the transmitter
cabinet (see Figure 1). Retain
hardware.
Figure 1: Exciter front panel screws
(f) Pull the exciter away from the cabinet
and unclip the exciter slides by
pressing in on the black tabs in the
center of the slide (see Figure 2).
Figure 2: Slide tabs
(g) Carefully place the exciter on a
suitable work area.
(h) Temporarily remove top cover from
exciter. Retain hardware.
(i) Permanently remove the cover plate
from the rear of the exciter (A2)
secured by four screws (see Figure 3).
Figure 3: Cover plate
(j) Install hardware to mount the site
interface PWB as follows.
Insert eight M3 screws (HMSP12)
through the holes in the rear of the
exciter so that the screw heads are on
the inside of the assembly (see Figure
MD-4 for location).
From the rear of the exciter/control
assembly, install eight M3 tooth
washers (HMW10) over the screws
and then eight M3 pillars (HMP05) on
the ends of the (HMSP12) screws.
The screws will protrude through the
other side of the pillars.
Install the NAPI80 over the extruding
screws and secure in place using
eight M3 plain washers (HMW02),
eight M3 split washers (HMW32) and
eight M3 nuts (HMN02).

(k) Connect the 20-pin ribbon cable
provided with site interface PWB
between J1 of the site interface PWB
(A2A4 in the Vector-HP) and J10 of
the remote interface PWB (A2A3 in
the Vector-HP).
Note the orientation of the connectors.
The red wire on the ribbon cable
should be connected to pin 1 (left-
hand side) of J1 on the site interface
PWB and J10 on the remote interface
PWB.
(l) Replace top cover removed in step
(h).
(m) Place exciter back rack slides and
push back into rack.
(n) Replace the four front panel screws
removed in step (e).
(o) Replace all connection removed from
the rear of the exciter in step (d).
3.2 Installing NAPI80 in Vector-LP
transmitter
(a) Press RF Off on the transmitter’s front
panel. Switch off the ac power to the
transmitter.
(b) If the optional battery is used, switch
off the dc power source to transmitter.
(c) Ensure the ac and dc power sources
are “locked out” so that they cannot be
turned on during this procedure.
(d) Open the front door of the transmitter.
(e) Using eight M3 screws (HMSP09F)
install the site interface PWB on the
pillars located on the rear of the front
door.
(f) Connect the 20-pin ribbon cable,
provided with site interface PWB,
between J1 of the site interface PWB
(A4 in the Vector-LP) and J10 of the
remote interface PWB (A3 in the
Vector-LP).
Note the orientation of the connectors.
The red wire on the ribbon cable
should be connected to pin 1 (left-
hand side) of J1 on the site interface
PWB and J10 on the remote interface
PWB.
(g) Close the front door of the transmitter.
4 TRANSMITTER SETTINGS
Once the site interface PWB has been
installed in the transmitter, configure the
transmitter to recognize it as follows:
(a) Disable all lockouts and enable the
transmitter’s ac power and dc power
(if necessary).
(b) On the front panel GUI’s Select
Peripherals menu, select the Site
Control Board as installed. See
paragraph 3.6.13.5 of the Vector-LP
manual or paragraph 3.6.12.5 of the
Vector-HP manual.
5 CONFIGURATION OF CONTROL/
MONITOR POINTS
Configure the control and monitor points as
detailed in paragraph 3.6.14 of the
Vector-LP manual or paragraph 3.6.13 of
the Vector-HP manual.
For information about connecting the
NAPI80 Site Interface PWB to an optional
ECMP, see the ECMP’s manual.
