Time Slot: (A or 0~9)

To support systems that include multiple Transceivers using the
same Frequency Channel, AirTime Transceivers can
automatically determine their position in a network of
transceivers. In most cases, the ATX6 will determine its own
position by listening to transmissions from other Transceivers in
the area. To select this feature, set the parameter value to
Automatic.
In installations with an ATX Transceiver receiving the time from
WWVB and transmitting it to multiple ATX6's or a combination of
ATX6's and ATX Repeaters, Channel Interference may be avoided
by setting specific "Transmission Slots" for each Transceiver. The
ATX and ATX6 Transceivers can be set to transmit on one of ten
Transmission Slots, numbered 0 through 9. When manually
selecting a Transmission Slot following this chart will often
provide the best results:

RC Emulation
(0/1)
Use the INC button to toggle between Enabling ('1') and
Disabling ('0') the transmission of radio signals to synchronize
Lathem's RC-series Wall Clocks. If there are no RC-series Wall
Clocks in the system, or if they are to be controlled by a
separate RC-MASTER, then RC Emulation should be disabled.
Press SET when the correct value shows.

Receive Mode:
Automatic:
If RS485, 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:
Receive Mode is entered by pressing and holding RECV (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 Receive 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.
Radio 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.
Receive Mode can be terminated by pressing and holding RECV
(NXT) for 2 seconds, indicated by the '~' symbol extinguishing on
display.
