Model 1092/1093 Program ROM Update
1 Introduction
This document provides instruction to replace the program ROM (firmware) in the Model 1092A/B/C
and Model 1093A/B/C series GPS Satellite Controlled Clocks. Basic understanding of electrical safety and
static protection is expected.
2 Required Equipment
1. Torx T-25 or large flat-blade screw driver
2. IC Removal Tool, curved tweezers or small blade screwdriver
3 Saving Original Configuration
Updating the firmware will erase the clock’s configuration. Document the existing settings for reference.
1. 1092B and 1093B/C: press SETUP and sequentially scroll through the various menus.
2. Press ENTER on any menu to sequence through that menu’s settings.
3. 1092A and 1093A: unfortunately, many settings cannot be queried. Use the Operation Manual for a
list of serial commands to set local offset, Daylight Saving Time, broadcast modes, IRIG-B time and
control functions, etc.
4 Disassembly
1. Disconnect power.
2. Remove from service.
3. Remove the four screws securing the cover with a T-25 driver (or flat-blade screwdriver).
4. Lift off the cover.
5 Installing the Program ROM
1. The program ROM is located at U2 (see Figure 1 on page 4).
2. Remove the old program ROM using the appropriate IC removal tool.
3. Install the new ROM. Observe the correct IC orientation and make sure the IC pins line up well on
both sides of the socket. If necessary, use a pin-bending tool to line up the pins.
4. Option 28: If present, the Power System Time, Frequency, and Phase Monitor may also require an
update ROM. Follow the separate instructions for the update steps.
6 Reassembly
1. Replace the cover.
2. Install the four screws securing the cover with a T-25 driver (or flat-blade screwdriver).
3. Place into service.
4. Connect the power.
5. Set to factory defaults.
7 Configuration
7.1 Factory Defaults
7.1.1 Front Panel (B and C Models)
