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)
