GDX-350 Sensor Transmitter
P/N: 5600-9001 Rev 2 43
GDA-400 base stations must have their Communications menus set for Wireless Receiver mode as
shown in Figure 5-12. In Receiver mode the GDA-400 may have 1-4 channels configured to receive input
data from 1-4 GDX-350 sensor transmitters.
Channel input type is configured in the ANALOG SETUP menu located within the Input/Output Setup
menus as shown in Figure 5-13. GDX-350s transmit 200 counts for 0% and 1000 counts for 100% full
scale readings so Input Min/Max menu values should be 200 & 1000. The Rmt. Xmitter ID menu entry
must match the Remote Id address setting
in the GDX-350 providing data to this GDA-400 channel
.
Voltage level of the 3.6 volt lithium battery in this GDX-350 is also displayed on this screen. The most
recent A/D Counts value is displayed at bottom of the screen.

5.10. System Security
The SYSTEM SECURITY menu in Figure 5-14 offers two levels of protection. A LOW level allows CAL
MODE sensor calibrations but requires the 4-digit Pass Code prior to altering menus. HIGH level locks
the entire menu database and CAL Mode until the correct Pass Code is entered. LOW and HIGH
security levels always allow viewing of configuration menus but they may not be changed. Contact Name
is a 12 character ASCII field available for displaying a phone # or name of personal who know the Pass
Code. Lost Pass Codes may be recovered by entering the locked security menu and holding the UP key
for 5 seconds. The 4-digit code appears near the bottom of the screen.
