ATX6 Installation and User Guide

Page 1

Introduction:

Lathem’s ATX6 is a Wireless Transceiver that can function in both

“Master” (Primary), and “ epeater” (Secondary) modes.

In “Master” mode, the ATX6 can wirelessly transmit clock

synchronization signals to Lathem AT series Wall Clocks, to other

Lathem ATX-series Transceivers in epeater mode and to Lathem C

Series Wall Clocks. It can provide S485 Wired synchronization signals

to Lathem LT x-512 and LT -0 Master Clocks and to DWA-S Bell

ingers. It can also provide a “Dry-Contact” closure to synchronize

other timekeeping systems.

As a “Master”, the ATX6 can synchronize its internal crystal-controlled

eal-Time-Clock to “Atomic” references that include GPS and Network

Time Servers and other system references.

In “Repeater” mode, the ATX6 can receive and synchronize itself to

another ATX series Transceiver in Master mode and re-broadcast the

signal according to the AirTime Protocol, same as described above in

“Master” mode.

The ATX6 can be set to transmit its radio signal at any of several

frequencies licensed to Lathem’s AirTime system by the FCC, at either

a 4 Watt or 6 Watt output power level. With an optional external

amplifier that can boost the signal to 20 Watts.

1. Choose an appropriate location to install the ATX6 on a wall.

a. If you intend to use the ATX-GPS accessory to

synchronize the ATX6, then a site should be selected

that is within the 25-foot cable limit of the ATX-GPS to

a window or skylight having an unobstructed view of

the sky.

b. If the ATX6 will be used in synchronizing a wide area /

campus, then the site should, generally, be close to the

center of the facility; rather than at the perimeter.

c. If you intend to synchronize the ATX6 to an ATX

Transceiver in Master mode then select a site within

approximately 130 feet from where the ATX

Transceiver will be located..

2. If synchronizing another system to the ATX6, or if

synchronizing the ATX6 to another system via “Dry Contact”

( elay) Closure, install the shunt jumper onto the circuit

board’s J7 Pins, according to the following diagrams:

CAUTION: Make sure the AC Power Cord is unplugged before

opening the ATX6 enclosure

To access the jumpers, remove the two screws from top case

cover.

Carefully slide the front panel assembly up until the jumper’s

location is accessible.

Change the jumper settings as needed

Slide the front panel assembly back into place and secure the

top case cover.

3. Mount the ATX6 on a suitable wall, according to the following

steps.

If mounting near a ceiling, make sure the top holes are at

least 2” away from the ceiling.

If an external amplifier will be used, mount the ATX within

feet of its location.

»After deciding the location where the clock will be mounted,

use the enclosed template to make the three marks for the

mounting screws.

»Drill a 5/16" hole at each of the marks

»Insert a wall anchor in each hole and tap it flush to the wall

with the hammer.

»Insert a screw into the top two wall anchors leaving 1/8"

exposed.

»Line up the two keyholes on the back of the case and slip over

the two screws.

»The lower mounting screw can now be inserted into the wall

anchor and secured.

4. Attach the UHF Antenna to the ATX6’s BNC Connector and

place it on top of the ATX6 or on a shelf within 12 feet.

If an external amplifier is used, attach the amplifiers cable to

the “ F IN” BNC connecter and to the BNC connector on the

ATX6. Connect the antenna to the “ANT” BNC connector and

place the antenna in the desired location. efer to function 19

of the setup on page 12, this function must be enabled when

using an amplifier.

For best performance, mount the antenna in a vertical position

not horizontal

5. If synchronizing the ATX6 to an ATX-GPS, attach the cable to

the J-45 Modular Jack, and mount the ATX-GPS according to

the instructions included in its package.

6. If synchronizing the ATX6 to a Lathem Master Clock or LT -GPS,

or if synchronizing a Lathem Master Clock or DWA-S to the ATX6

via S-485, install a Cat-3 or Cat-5 (UTP) Cable between the

Terminal Block connections on the ATX6 and the connections on

the other unit, taking note of signal polarity: plus to plus /

minus to minus.

7. If synchronizing the ATX6 to Lathem’s AirTime TimeSync

Software using an Ethernet to S232 Adapter (Lathem part #

TXTOSE ) and cable, install the Ethernet to S232 Adapter

according to the instructions included with its package.

Install and execute the AirTime TimeSync Software according

to the instructions included with its package.

8. If synchronizing another system to the ATX6, or if synchronizing

the ATX6 to another system via “Dry Contact” ( elay) Closure,

install a Cat-3 or Cat-5 (UTP) Cable between the Terminal

Block connections on the ATX6 and the connections on the

other unit.

9. If synchronizing another system to the ATX6 using the emote

Wireless elay Option, install the Wireless elay at the remote

location, according to the instructions in its package.

10. Connect the ATX6 to an AC Power Outlet using the integral

cable.

Apply a minimum of 3.5 to 4.5 lb-in torque for tightening field wires

into the terminal blocks. Use Cat-3 or Cat-5 Twisted-Pair Wires Use

only Copper Wire.
