8.3 Wireless Receiver Mode
Wireless Receiver mode is exclusively for wireless communication to our GDX-350
RF wireless sensor transmitters. In Receiver mode the radio connects to the GDA-
1600’s master port and receives input data from up to sixteen GDX-350 RF sensor
transmitters. Wired and wireless inputs may be mixed between the GDA-1600’s sixteen
channels so it is possible to also accept wired signals from analog input option PCBs.
Use the
Use the
WIRELESS RF900 setting shown at center of Figure 8.3 ONLY FOR
COMMUNICATION TO GDX-350 RF WIRELESS TRANSCEIVERS
for setting up wireless networks with other Modbus slave devices.
GDX-350 RFs transmit 200 counts for 0% and 1000 counts for 100% full scale readings
GDX-350 RFs transmit 200 counts for 0% and 1000 counts for 100% full scale readings
so
Input Min/Max menu values should be 200 and 1000. The Remote ID menu entry
must match the
Remote Id address setting in the GDX-350 RF providing data to this
GDA-1600 channel.
Input Req is typically set to VALUE but also allows a BATT
entry into this field. Entering BATT causes the channel to display (and alarm) from
battery voltage levels at this GDX-350 RF. Voltage level of the 3.6 volt lithium battery
in this GDX-350 RF is also displayed on this screen.

INPUT DATA FROM menu is set for WIRELESS
RF900, in addition to processing the GDX-350 RF’s 10-bit “counts” value, it also
receives status bits indicating
Communications Error, Low Battery and
Calibration.
•
Communications Error – Each channel’s 30-minute trend screens (Figure 8.4)
are very useful for diagnosing wireless problems since it indicates amount of time
since the most recent transmission was received. The down arrow on top of the
trend screen resets to far right each time a transmission is received by that
channel. When not in alarm, GDX-350 RFs transmit each 5-minutes so the arrow
should never progress past the 5-minute interval. The GDA-1600 activates the
channel’s FAULT alarm and indicates
ComErr
if no transmission has been
received in 18 consecutive minutes.
•
Low Battery status indicates the GDX-350 RFs integral 3.6V lithium D cell has
dropped to below 3.3V and should be replaced very soon.

the GDA-1600’s LCD readout and the Alarm 3 LED flashes. Relays are not
