To abort the search, swipe the PROG marker while in search mode. The unit will abort the search and will
not save any CXT sensors or RXT-320’s found up to that point.
4.3.4 Set RF Silence and RF Sleep
The SET RF SILENCE AND RF SLEEP menu allows the user to initiate radio silence over the whole
network. Radio silence terminates communication between all the RXT-320 transceivers in the network.
This menu also allows the user to initiate RF sleep for a set amount of time. This sleep function lets the
CXT controller broadcast a sleep command to all of the CXT sensors and RXT-320 transceivers in the
network and is used as a power saving feature. Upon entering this menu, the LCD will display:
RF SILENCE AND SLEEP
RF SILENCE: | RF SLEEP:
| ##:##
XXX | SLEEP:XXX
Swipe the magnet over the markers of the up or down arrows to move the arrow prompt “→” to the desired
location. A swipe over the ENTER marker for RF SILENCE and SLEEP will toggle the value between ON
and OFF. For the sleep timer, a swipe over the ENTER marker will select the function indicated by the
arrow prompt “→” and the value can be changed by swiping over the markers of the up or down arrows.
Another swipe over the ENTER marker will save the selected value. The sleep timer has a range from 0 –
5 minutes and is set in minutes and seconds.
RF Silence is used to prevent the radios from possibly interfering with other RF devices on site (such as
remote detonators). Once set to ON, it will stay on until the user turns it OFF. In RF silence, the sensors
are not monitored and no alarms can be activated. When sleep is enabled, the sensors are each polled once,
and then the wireless transceivers are turned off for the sleep period. Once the sleep period expires, the
transceivers are turned back on and the sensors are polled once more. This cycle repeats indefinitely. The
sensors are not updated and the alarms are not activated while the wireless network is asleep. The longer
the sleep time, the longer the possible delay between alarm conditions occurring and the alarms being
activated. However, a longer sleep period will increase the battery run time.
4.3.5 Set COMM Baud Rates
The SET COMM BAUD RATES menu displays the current baud rate settings for COMM1 (master) and
COMM2 (slave). Upon entering this menu, the LCD will display:
SET COMM BAUD RATES:
COMM1 BAUD RATE:9600
COMM2 BAUD RATE:9600
NOTE: SET COMM BAUD RATE is not utilized with the CXT controller. Both the
COMM1 Master and COMM2 Slave should be set to 9600 and not changed. Changing these
settings may cause the unit to become inoperative.
4.3.6 Set Modbus Timeouts
The SET MODBUS TIMEOUTS menu allows the user to set the response timeout for Modbus™
communications and the inter-poll delay. Upon entering this menu, the LCD will display:
SET MODBUS TIMEOUTS:
RESPONSE TIMEOUT:###
INTERPOLL DELAY:###
