FM13016D: NX15 to NX400 Transmitters -
Replacing the Single-Board Computer (SBC)
Field Modification
1 INTRODUCTION
This document provides instructions for Nautel customers or their appointed agents to modify
the subject equipment in the field.
1.1 Reason for Modification
A new generic SBC (Nautel Part # 207-8720) must be used as the replacement if the original
fails. The new SBC is electrically compatible, but depending on the vintage being replaced,
there are physical differences in the connector locations/styles.
1.2 Equipment Affected
This modification affects the following NX series AM broadcast transmitters:
models with Nautel Part # 207-8710, 207-8710-01, 207-8710-02, 207-8998, 207-8998-01
SBC installed (containing UB97).
models with the original Door Computer assembly Nautel Part # 207-8708 or
207-8708-01 (containing UB66).
models with Field Mod # FM13016, FM13016A, FM13016B, or FM13016C installed.
If your transmitter or spare NAPC160* PWB was shipped between May 2019 and November
2021, please follow IS21007* – NX Series – Upgrading Controller Firmware (NX SW 5.0).
1.2.1 Minimum Software Required
Replacing the SBC requires that your NX transmitter have software version 4.0 (or 4.7 for
NX15), as a minimum. If the transmitter is operating with software version NX SW3.x or
earlier, follow the instructions in Information Sheet IS13005* in the latest software directory
located in www3.nautel.com/NX_Series/ to complete the required software update.
1.3 Responsibility for Implementation
This modification is written for qualified transmitter maintenance personnel.
1.4 Scheduling
Implement this procedure at the convenience of station maintenance personnel noting that
the transmitter will be “off-air” if a software upgrade is required.
1.5 Manpower Requirements
Completing this modification requires approximately one (1) hour.
1.6 Special Tools/Test Equipment
Standard Phillips screwdriver
7 mm nut-driver/socket
USB mouse for touch-screen calibration (if compact flash card is replaced)
USB Keyboard along with IS18005* (may be required for initial startup of the
transmitter - visit www3.nautel.com/NX_Series/ to obtain this IS document)
1.7 Materials
The parts required for this modification are contained in the provided Field Modification kit
(Nautel Part # 207-9005-05), see Table 1.

1.8 Identifying Modified Assemblies/Parts
Identifying modified assemblies informs future maintainers of the current configuration. Mark
the transmitter with “FM13016D” next to the serial number label using indelible ink to indicate
it has been modified.
1.9 Publications Affected
The Single Board Computer Assembly (A40A1 – NX15 to NX50, or A65A1 for NX100 to
NX300, or A62A1 for NX400) has been replaced with Nautel part # 207-8720. Make the
following changes to the NX Troubleshooting manual:
NOTE
Strikethrough text in the following tables indicates existing information in the Troubleshooting
manual that requires editing. The text after is the new information to be added (i.e., P33-6 is
now P33-1).

Manual with the applicable schematic provided with this document.
2 REPLACEMENT PROCEDURE
Remove the SBC as follows:
NOTE
The replacement SBC assembly is static sensitive and can be damaged by electrostatic
discharge (ESD). Observe the static precautions described in the NX series technical
documentation.
(a) Open the front door of the NX transmitter to access the SBC.
(b) Remove the old SBC cover (Nautel part # 207-8292) using a 7-mm nut-driver/socket to
remove the seven (7) M4 hardware, which holds the SBC's protective cover to the front
door of the transmitter. Retain hardware. See Figure 1.
Figure 1: SBC Cover Removal
(c) Disconnect the power connector (P30) from the original SBC.

Page 6 NX15 to NX400 Transmitters - Replacing the Single-Board Computer (SBC)
Issue 1.0 FM13016D
(d) Disconnect the remaining connectors from the SBC as follows:
No label – VGA
No label – COM
W66P2 – SBC Streaming Bus
W67P2 – SBC External Serial
P33 (NX25/NX50) or P35 (NX100 to NX400) – SBC Reset
(e) Using the label set (Nautel Part # 207-8999-02) provided with the Field Modification kit,
replace where applicable or apply new mating labels to connectors P30, P33 (or P35),
P36, P37, COM2, VGA, U10HDMI, W67P2 and W66P2 to reflect their new mating
connectors as shown in Table 2. Label both ends of COM2 and P101/P102 cable.
NOTE: Use labels "A40" for NX25/NX50 (e.g., A40A1U1PWR2). Use labels "A65" for
NX100 to NX300 (e.g., A65A1U1PWR2). Use labels “A62 for NX400 (e.g.,
A62A1U1PWR2).

(h) Remove the four (4) M3 screws and the three (3) M3 pillars (Nautel part # HPM45)
securing the SBC to the chassis. See Figure 3.
Figure 3: SBC Hardware Removal
(i) Remove the SBC and discard. See Figure 4.

(j) Install the new SBC Mounting Bracket (Nautel part # 206-8091) using the seven (7) M4
screws (Nautel part # HMSF08). See Figure 5.
Figure 5: SBC Bracket Installation
(k) Install the new SBC (Nautel part # UB118) to the SBC Mounting Bracket using the six (6)
sets of 6-32 hardware. Leave the two indicated screws loose for SSD installation in step
(m). See Figure 6.
Figure 6: SBC installation

NX15 to NX400 Transmitters - Replacing the Single-Board Computer (SBC) Page 9

(l) Mount the SSD Drive (Nautel part # 219-2131) to the Mounting Bracket (Nautel part #
206-8110) using the four (4) M3 screws. See Figure 7.
Figure 7: SSD Drive Mounting
(m) Mount the SSD Drive assembly from step (l) to the SBC Mounting Bracket by sliding the
assembly over the loosened screws from step (k). Tighten the two screws. See Figure 8.
Figure 8: Attaching the SSD Drive assembly to the SBC

Page 10 NX15 to NX400 Transmitters - Replacing the Single-Board Computer (SBC)
Issue 1.0 FM13016D
(n) Using Table 2 and Figures 9 and 10, connect cables to the new SBC. COM3 and COM2
are keyed connections so they cannot be inserted incorrectly. Connect the unlabeled
COM cable to COM1 on the new SBC.
Figure 9: SBC Connections
Figure 10: SBC COM Connections
(o) If Field Modification FM13016 or FM13016A was previously applied to the transmitter, the
UB97 Reset Adapter Assy PWB (207-5760) can be disconnected from P33 or P35, then
P33 or P35 can be connected directly to A1U1RST_BTN1. Otherwise, connect P104 to
P33 (NX15/25/50 only) or P35 (for NX100) and P103 to A1U1RST_BTN1 on the SBC.
See Figure 11.
(p) Locate the multi-connector cable (Nautel Part # UA312) in the 207-5060-01 Cableset,
provided with the Field Modification kit. Mate the largest connector with J1 of the SSD
installed in step (m). Connect the other ends to the SATA1 and SATA_PWR1 connectors
on the SBC (see Figure 9).

3 REBOOT & TOUCHSCREEN CALIBRATION
IMPORTANT
Inserting a new compact flash card or SSD drive will prompt a software upgrade which
requires the transmitter to be “off-air”. Various settings (i.e.; User Accounts, Network Setup,
Email Configuration, Notifications, NTP Servers) and logged data will not be saved in the
transmitter when you replace the compact flash card.
NOTE
The OS password document, provided with the transmitter, should be kept in a secure
location for future reference. This password is needed in the event access is required to the
transmitter’s operating system.
(a) If the AUI fails to load and the BIOS boot setting was confirmed, the compact flash card
or SSD drive may be corrupted. Turn RF Off and disconnect power to the SBC (P30
connector).
(b) Remove the old flash card or SSD drive and insert the replacement programmed SSD
Mod (Nautel Part # 219-2131) provided with the Field Modification kit.
(c) Re-connect power to the SBC (P30 connector) and verify BIOS boot settings again (refer
to IS18005).
(d) The touchscreen monitor will turn on and a screen will appear prompting you to perform a
software upgrade. The AUI will not navigate away from this page until it has been
completed. Plug in the USB mouse and begin the upgrade. Refer to the Non-standard
Maintenance section of the transmitter's Operations and Maintenance Manual if you
require assistance with installing the software.
(e) Login to the AUI using the default username “Nautel” leaving the password blank.
(f) Perform a touch screen calibration through the AUI (in Menu ►System Settings ►
Screen Configuration). Using the USB mouse to navigate to the touch screen calibration
page, and then use your finger to touch the targets.
(g) Do an ac power cycle after the software upgrade and touch screen calibration is finished.
(h) Unplug the USB mouse and reconfigure the network settings in the Network Setup page
(in Menu ►User Settings).
(i) Reconfigure the User Accounts settings (in Menu ►User Accounts), Email
Configuration, Notifications, NTP Servers, Nautel Phone Home, SNMP Configuration
settings (in Menu ►User Settings) and Audio Player settings (in Menu ►Audio Player,
then enable in Presets menu).
(j) Turn RF On and return to normal operation.
The modification is complete.
