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.

Operating Modes:
Normal:
In Normal Mode, the ATX6 will listen for synchronization signals from
the device selected as the Time eference (Set-Up parameter # 7). If
an external Time Source is selected, the ATX6 will synchronize its eal-
Time-Clock to that source, when the synchronization signal is received.
In the event of a power failure, the TC Date and Time parameters are
protected and continue to operate using a Lithium “coin-cell” battery.
In Normal Mode, the ATX6 transmits a radio signal (indicated by the
UHF LED flashing once) to other ATX-series devices during the last ten
seconds of each minute, If C Emulation is enabled (Set-Up parameter
# 15), the ATX6 will transmit a radio signal to C-series Wall Clocks at
the top of each odd minute; except the minute designated to generate
a relay closure (see below). If an external amplifier is used, the ATX6
will transmit a signal every 15 minutes of each hour.
If “Dry Contact” ( elay) synchronization is not selected as the time
reference (Set-Up parameter #7 is not equal to ‘Syn’), then the ATX6
will activate the local elay [and Wireless emote elay (option)] at
the selected HH:MM:00.
If 485 is not selected as the time reference (Set-Up parameter #7 is
not equal to ‘485’), then the ATX6 will transmit the S-485 protocol to
synchronize Lathem Master Clocks and Bell ingers that support the S-
485 interface at the 40
th
second of each minute (HH:MM:40). This is
indicated by the 485 flashing indicator once.
Each day for 15 minutes, beginning at 1:05AM, 3:05AM and 10:45PM the
ATX6 will listen to and re-evaluate its radio environment, to determine
if any Automatic Time Slot adjustment is required. During this period,
the “~” symbol will flash and radio transmissions are inhibited.
Transmission parameters are automatically adjusted, as may be
necessary. If another AirTime Transceiver (ATX or ATX6) is selected as
the time reference for this unit (Set-Up parameter #7 is set to ‘Air’),
then this ATX6 will synchronize its clock to the received transmission.
The ATX6 will indicate when it receives a signal by the UHF LED
flashing twice.

ATX6 Installation and User Guide
Page 15
If ‘PcL’, ‘485’ or ‘GPS’ is selected as the time reference, the ‘PCL’,
‘485’ or ‘GPS’ LED will flash twice each time a valid signal is received.
The ‘485’ or ‘UHF’ LED will flash once each time a signal is transmitted
by the ATX6.
AirTime Transmit Mode:
Automatic:
When not in eceive Mode (automatically or manually initiated) the
ATX6 will transmit the C radio signal each odd minute (if C Emulation
has been enabled). The ATX6 will transmit the AirTime radio signal
each minute, or each even minute (if C Emulation has been enabled).
When an external amplifier is used, the ATX6 will transmit an AirTime
signal 4 times per hour.
Manual:
Transmit Mode is entered by pressing and holding T NS (SET) for 2
seconds, and is evidenced by the ‘~’ symbol appearing in the display
solidly and the UHF LED flashing once each time it transmits a signal.
When AirTime Transmit Mode is active, the ATX6 will transmit the
AirTime synchronization signal to all ATX-series devices, once every 10-
seconds for one hour. This can be helpful when installing and testing
other ATX-series devices in the system.
If the T ANSMIT (SET) button is pressed during the 15-minute eceive
Mode that occurs automatically upon unit power-up and during the
period beginning at 1:05AM, 3:05AM and 10:45PM each day, or as a
result of manually starting eceive Mode (see below), transmissions will
not occur until eceive mode has expired or been cancelled.
During AirTime Transmit Mode, all other Normal operations (except C
radio transmissions) will continue. Transmit Mode can be terminated by
pressing and holding the T NS (SET) button for 2 seconds, and is
evidenced by the ‘~’ symbol disappearing from the display.

Receive Mode:
Automatic:
If S485, GPS or Air have been selected as the synchronization type (in
Set-Up Parameter #7) , then the ATX6 will automatically enter a
“listen” mode for 15 minutes after power up and each day at 1:05AM,
3:05AM and 10:45PM. This is indicated by the “~” symbol flashing. The
UHF LED will flash twice during this time each time a signal is received.
Manual:
eceive Mode is entered by pressing and holding ECV (NXT) for 2
seconds, and is evidenced by the ‘~’ symbol appearing in the display
solidly. The UHF LED will flash twice each time a signal is received.
When eceive Mode is active, the ATX6 will listen for AirTime signals
transmitted by other ATX-series devices for one hour, allowing it to
configure itself as a member of the AirTime Network. This is helpful
when installing and testing other ATX-series devices in the system.
adio transmissions are inhibited during receive mode.
If another AirTime Transceiver (ATX or ATX6) is selected as the time
reference for this unit (Set-Up parameter #7 is set to ‘Air’), then the
ATX6 will synchronize its clock to the received transmission.
eceive Mode can be terminated by pressing and holding ECV (NXT)
for 2 seconds, indicated by the ‘~’ symbol extinguishing on display.
