1095A/C Quick Setup Guide

1095A/C Quick Setup Guide
This document covers the basics of getting the Model 1095A/C unpacked, installed and running.
For complete details covering the Model 1095A/C, please consult the operation manual available
for download from www.arbiter.com, or purchase a printed copy through Arbiter Sales.
1095A/C Clock Differences
Model 1095A/C may be ordered with and without an external antenna. Clocks without an external
antenna have an internal GPS antenna. Clocks may also be purchased with either an opaque or
transparent (smoked) cover, and with or without an LED time display.
Several accessories included with the clock are located inside the packing material. For clocks with
an internal GPS antenna, these accessories include a Programming Port Cable with RJ-11 to DB9
adapter (AS0067200), Quick Setup Guide (PD0052900) and Sealing Cable Port (HP0022601). If
ordered with Option 01 the clock also comes with a Grounding Block Kit (AS0048900) and GPS
Antenna (AS0087800). If included, handle the GPS antenna carefully as it may be damaged if
Attaching Mounting Hardware
Included Mounting Tabs
Included with each clock are four tabs and stainless hardware to mount the clock to a flat surface.
The clock may also be mounted to a pole using a worm drive adjustable strap (not included).
DIN Rail Mounting – Optional
Arbiter Systems sells an optional DIN rail mounting kit (AS0093700) that allows you to mount
the clock vertically or horizontally. For installation instructions, download DIN Rail Mounting
documentation (PD0045900) from the Model 1095A/C Arbiter website product page.
Installing Clock
Internal Antenna
The Model 1095A/C is designed to operate outside in the weather, and has a GPS antenna mounted
inside the enclosure. Mount the 1095 with top pointed up (the gland is on the bottom) so that the
GPS antenna has a complete view of the sky in all points of the compass.
External Antenna
If your clock was ordered with an external GPS antenna, it is designed to be threaded onto a piece
of 3/4 in pipe nipple. Follow these instructions to mount the antenna. Make sure to mount the
antenna so that it has a clear view of the sky in all directions of the compass.

1. Pass the antenna cable through the pipe nipple and attach the cable to the antenna. Tighten
by hand, and do not spin the antenna onto the cable connector, as it may damage the
antenna/cable connection.
2. Thread the pipe nipple into the base of the antenna and snug by hand.
3. Mount the pipe nipple to a fixture, such as the side or top of a building, or to a pipe. You
can also purchase the antenna mounting kit (AS0044600) available from Arbiter Systems.
4. Also available is a surge arrester (AS0094500) that can protect the Model 1094 from induced
voltages that may appear on the antenna cable and potentially damage the clock.
5. Connect the antenna cable to the clock so the clock can synchronize with the GPS.
Connecting Signal Cables
All input and output cables run through the gland located at the bottom of the clock, and attach
to the terminals on the mainboard. The only exception to this is that clocks with an external GPS
antenna will have a female Type F connector next to the gland. Figure 1 shows the connector block
inside the clock with labels to all the signal and power connections.

See Main Gland Specifications in the operation manual for details about wire type, especially if the
clock is mounted outside. NOTE: Strip the wire insulation about 1/4 in and DO NOT TIN the
bare wire with solder.
• Timing Outputs Model 1095A/C has four timing output ports, labeled PROG. PULSE A,
IRIG-B (unmodulated), PROG. PULSE B, and IRIG-B MOD. PROG. PULSE B can also
be selected for a separate and independent instance of IRIG-B unmodulated.
• Out-of-Lock Relay Connect the three wires – normally open (NO), normally closed (NC)
and common (COM) – to the SPDT relay contact terminals. “Normally” refers to the relay
condition with the clock powered off.
• RS232 ports Every Model 1095A/C has two RS232 serial ports: COM 1 and COM 2.
Connect a null-modem serial cable between the computer and the clock. The Programming
Port at J8 provides a convenient point to initially configure the clock. Use the phone cable
and RJ-11 to DB9 adapter to connect between J8 and the computer.
• Event Input The Model 1095A/C has one dedicated BNC event input. There are three
input voltage ranges: 5 Vdc to 12 Vdc, 24 Vdc to 48 Vdc, and 120 Vdc to 240 Vdc. Use the
separate terminals to select the input voltage range.
Energizing the Clock
Before connecting voltages to the clock, make sure to read the power inlet label to verify the correct
voltage. The Model 1095A/C accepts an unregulated input between 9 Vdc and 30 Vdc, at 2 W
max. Make sure that the voltage you are connecting is in the correct range supplied on the label.
Model 1095A Startup
The green Operate LED and the red Unlocked LED should illuminate, when power is first applied
to the Model 1095A. After a short time of tracking satellites, the Unlocked LED should go out.
After a few minutes1 of operation while being locked to the GPS, the green Stabilized LED should
light up.
These indications will only be visible with the opaque clock cover removed. With a transparent
(smoked) cover they are visible with the cover in place. Lock and stabilization times above depend
greatly on satellite reception, and are under fairly ideal circumstances2 .
Model 1095C Startup
When inlet power is first applied to the Model 1095C, you should see the green Operate and the
red Unlocked LED light up, and the large LED display should produce six dashes then zeros. After
a short time of tracking satellites, the Unlocked LED should go out and the time display will begin
counting. After a few minutes of operation, while being locked to the GPS, the green Stabilized
LED should light up and the Model 1095C should display the correct time.
Configuring the Clock Settings
Every Model 1095A/C is shipped from the factory with default settings, which can be changed
using the 1095 Utility software through one of the serial ports. This section discusses configuring
the clock using the front panel in which two common configuration examples are given. For a
complete configuration of the clock, download the pdf version of the manual, or order a printed
version (AS0096400) from Arbiter Systems.
Configuring Time and IRIG-B Settings
Two of the most common and important settings to configure on a clock are the Time and IRIG-B.
Time needs to be set up for a specific locale, and IRIG-B uses time zone settings in the time code.
It normally takes about four minutes to stabilize after achieving GPS lock.
Clock, or antenna, should be mounted with a clear view of the sky from 10 degrees above the horizon to directly
overhead for all points of the compass.
Download the 1095 Utility software from www.arbiter.com and start the program. Connect the
RS232 null-modem cable and adapter between your computer and the clock. Select Settings and
make sure you have the correct COM port and baud rate selected.
NOTE: To use the programming port (J8) set DIP switch 8 to ON.
1. Click the Read icon first to read the clock’s configuration. This also serves to verify your
connection to the clock.
2. Select the Time tab and adjust the Local Offset and Daylight Saving Time settings to your locale. For example, Eastern Standard Time in the U.S. is 5 hours earlier than UTC. Therefore,
the Local Time Offset would be –5:00.
3. Select the IRIG tab and set the Time Reference and IEEE 1344 Mode to your preference.
IRIG-B includes a time zone setting and can turn on the IEEE 1344 settings. When the IEEE
1344 is ON the IRIG-B includes extra bits for time quality and year information.
4. Click the Write icon to upload the new settings to the clock.
5. To verify that the newly uploaded configuration in the clock agrees with the utility settings,
click the Verify icon, which will indicate any differences.
6. You may also save this configuration for later use by clicking the Save icon.
