TXP-WTA_Instruction_Manual_(Rev1.3)
RF HANDSHAKING = OFF may be used for any application. OFF is required when broadcasting to a controller and/or
wireless relay configured as a Server with other controllers or wireless relays on the same network configured as
Clients.
9.1.8 *RF LINK
The RF Link will change the mode in which the TXP-WTA Sensor Transmitter will communicate. The default setting is
the Wavecast mode which is discussed in detail in Chapter 8. By selecting RF Link the mode may be changed to
Legacy Mode, which is discussed Chapter 10.
9.1.9 *TX POWER (900 MHz MODELS ONLY)
TX Power (900 MHz models only) may be set for 10mW, 200mW, 400mW and 1 watt (EIRP based upon a 2 dBi
antenna). Since TXP-WTA Sensor Transmitters are battery powered the TX Power setting should be as low as
possible to sustain reliable communication. The maximum TX Power setting is 30db (1 watt) and each time TX
power is reduced by half, antenna transmit power is reduced by 3dB.
NOTE: 1-watt operation is not recommended or necessary for most applications as it can cause an unnecessary load
on the battery thereby significantly reducing battery life.
Under normal operations the TX Power cannot be set to 1 watt. If conditions exist that require TX POWER set to 1
watt, perform the following:
1. On page 2 of the 900mHZ Radio menu, swipe the down key until the selecting arrow is at the very bottom
next to RF Link=....
2. Hold the magnetic wand on the up key until A1 & A3 LEDs flash, after about 5 seconds.
3. Now 1 watt is available for selection.
2.4 GHz variation: The TX Power Menu is not available in 2.4 GHz models and is fixed at 125mW conducted.
9.1.10 TX CNT (TRANSMIT COUNTER)
TX Cnt. (Transmit Counter) appears at the bottom of the RF LINK page 1 and is an 8-digit hexadecimal counter that
appears as 0x00000000. The highest count would be 0xFFFFFFFF, or 4,294,967,295 decimals. It is useful as a
diagnostic tool for counting how many times the TXP-WTA Sensor Transmitter broadcasts over any given period.
To reset the TX CNT:
1. Hold the CAL/DOWN key when on the RF Link Setup Menu.
When in dual channel mode, this number combines the transmissions from each channel.
9.2
Clock, Warm up and CAL Purge Delays
The TXP-WTA Sensor Transmitter is equipped with a Real-Time Clock and Calendar, so Time and Date must be set to
correctly match its location. They are set at the factory in a 24-hour format but may require adjustment to match
the location's time and date after shipment.
Warm Up and Cal Purge time delays are also available to prevent unwanted alarm trips. Figure 8 3 shows the menu
for these items.
