What This Manual Covers
This manual describes the set up and operation of the Model 1092A/B/C and Model 1093A/B/C
series satellite-controlled clocks.
How to Determine Firmware Version Date
To display the firmware date for your instrument (Models 1092B, 1093B and 1093C only) press
and release the SETUP key at power-up and the date should appear briefly on the LCD display.
To display the firmware date for Models 1092A, 1092C and 1093A, use the main RS-232 port (see
page 10.2.15). To determine the current firmware date for this product, see the Arbiter website
under the specific product name.
Firmware Updates – Main Board
Clocks with an main board require a ROM change to update firmware. This version of the manual is
written for clocks with a ROM current with the publishing date of this manual (see page v). Where
applicable, this update may include new documentation, such as a new version of this manual.

Unpacking the Clock
1.1 Introduction
This section will assist you with unpacking the clock from its shipping container; other parts and
accessories shipped with the clock include:
•1093A/B/C GPS Clock (includes internal power supply)
•1092A/B/C GPS Clock (includes external power supply)
•Antenna Cable, 50 feet with connectors
•GPS Antenna
•Rack-Mount Ears, 2 ea. (1093A/B/C only)
•Instrument Manual
1.2 Precautions
Mechanical Shock Note that the GPS antenna is small and smooth, and can be damaged if
dropped. Use care when handling. Remember to store the antenna in a safe place before the final
installation.
Static Discharge Note that the Model 1092A/B/C and 1093A/B/C are electronic devices and
use static-sensitive components in their operation. Therefore, use care when handling against static
discharges. Generally, these components are protected in their normal situation, however some of
these are accessible when the cover is removed.
CAUTION Antenna Input Connector - Connect only the antenna cable coming from the
antenna into this connector. The antenna input connector on the clock itself leads to the GPS
receiver, which could be damaged from high voltage or a static discharge. To protect the GPS
clock from electrical discharges during operation, consider the optional surge suppressor (Part no.
AS0049000). For more information see Section 4.3.

2 Unpacking the Clock
1.3 Unpacking and Locating Accessories
The Model 1093A/B/C, and included accessories, are packed between two closed-cell foam shells
(see Figure 1.1). The Model 1092A/B/C series clocks are packed between layers of molded foam
pieces. Carefully pull apart the two shells to extract the clock and accessories. Some of the
accessories (i.e. antenna and rack-mount ears) are located in one of these shells for protection.
In the diagram below, you can see how the GPS antenna and rack-mount ears are located in the
closed-cell foam marked with the label that reads,
ADDITIONAL PARTS INSIDE
Figure 1.1: Packaging of Accessories
Antenna cable, clock and operation manual are located between the two pieces of closed-cell
foam. The rack-mount ears and antenna are embedded in the packing foam side labeled ADDI-
TIONAL PARTS INSIDE.
1.4 Attaching Rack-Mount Ears to 1093A/B/C Series Clocks
Each Model 1093A/B/C comes with two rack-mount ears suitable for mounting in a 19-inch system
rack. These ears have four mounting holes, two of which are used to attach them to the sides of
the clock. Since it is required to remove the M25 x 10 mm screws which attach the cover to the
chassis, it may be good to attach the ears after first making any jumper configuration inside the
clock. You will want to return to this section after making these changes.
1.4.1 Mounting Instructions
1. Using a Torx T25 driver or large slot screwdriver, remove the four M5x10 screws attaching
the clock cover to the chassis. Use either a T25 or large slot screwdriver.
2. With the ear facing out from the front panel, match the lower set of holes of the ear to the
cover/chassis and remount the M5x10 screws.
3. Repeat this procedure with the other side of the chassis and other ear.
