TXP-WTA_Instruction_Manual_(Rev1.3)
2. TX Retries set to 4: the TXP-WTA Sensor Transmitter transmits until an acknowledgement is received from
the Server or four times, whichever comes first.
3. TX Retries set to 5: the TXP-WTA Sensor Transmitter transmits until an acknowledgement is received from
the Server or five times, whichever comes first.
9.1.5 *TX Config Time
TX CONFIG TIME may be set from 0 to 18 hours and determines how often the TXP-WTA Sensor Transmitter
broadcasts all of the CHANNEL CONFIG parameters to the controller and/or wireless relay.
Broadcasts normally include only monitored gas values and alarm status, but at least hourly, all configuration is sent
to the controllers to assure identical readings at all locations. The configuration data is also broadcast automatically
whenever any of these parameters are edited, or manually by holding the UP key until the display shows Release
Key. This longer broadcast takes approximately 1 second to complete.
Setting TX Config Time to 0 means that the TXP-WTA Sensor Transmitter will not send the Channel Config
parameters to the controller and/or wireless relay automatically.
To send these parameters to the controller and/or wireless relay:
1. Hold the magnetic wand on the UP key until the display shows Release Key, then release the key by pulling
the magnet away.
9.1.6 RF Link Status
RF Link Status opens another screen that shows if the TXP-WTA Sensor Transmitter is In-Range of the Server and
what the battery voltage is currently. The radio remains active during this display so that the range status is
displayed in real time. Battery voltage is also displayed on the MAIN MENU.
* TX Retries (900 MHz and 2.4 GHz), RF Handshaking (900 MHz) and TX Power (900 MHz) Menu settings are available
to improve communications reliability by increasing the quantity and power of wireless broadcasts.
IMPORTANT! Ensure proper selection and location of antennas before increasing TX Retries and TX Power settings.
Battery life will be reduced by increasing these settings. Proper selection and location of antennas is more
important to successful communications and will not sacrifice battery life.
9.1.7 *RF HANDSHAKING (900 MHz MODELS ONLY)
RF Handshaking must be OFF if there is more than one controller and/or wireless relay receiving TXP-WTA Sensor
Transmitter broadcasts.
•
The default OFF setting causes every TXP-WTA Sensor Transmitter broadcast to repeat 3 times in rapid
succession (these appear as a single blink of the TX LED and are unrelated to TX Retries).
•
The ON setting requests an Acknowledge, or, "Handshake" from the Server.
With RF Handshaking = ON, the TXP-WTA Sensor Transmitter broadcasts only once if the Acknowledge is received,
and up to 3 times if an Acknowledge is not received.
IMPORTANT! THE ON SETTING ALLOWS MORE EFFICIENT COMMUNICATIONS BUT MUST ONLY BE UTILIZED WHEN
BROADCASTING TO A SINGLE CONTROLLER OR WIRELESS RELAY CONFIGURED AS SERVER. MULTIPLE
CONTROLLERS/WIRELESS RELAYS, LISTENING ON THE SAME NETWORK ID, WILL HAVE ACKNOWLEDGE DATA
COLLISIONS IF THE SENSOR TRANSMITTER RF HANDSHAKING = ON.
