Menu Item Description
Radio Status
Opens another screen that shows if the RF GDX-350 is In Range of the Server and
what the battery voltage is. Battery voltage is also displayed on the “EC INPUT PG.
2” screen.
* TX Multiples
Menu settings are available to improve communications reliability by increasing the
quantity and power of wireless transmissions.
IMPORTANT: Ensure proper selection and location of antennas
before increasing TX Multiples and TX Power settings! Battery life
will be reduced by increasing these settings. Proper selection and
location of antennas contributes much more to successful
communications, without sacrificing battery life, than these settings.

5.9. Base Stations
Figure 5-12 shows correct settings for the GDA-1600 base station’s “Data From” menu to receive data
from RF GDX-350s. Each controller channel’s Remote ID must match the GDX-350’s Remote ID setting
in order for its VALUE to appear on the desired controller channel. The GDX-350 counts value equals 75
counts, or -15.6%, during CAL MODE. Enabling the GDX-350’s “INPUT MARKER” menu as shown on the
right menu in Figure 5-12 causes the GDA-1600 controller to indicate IN CAL when the GDX-350 has its
CAL MODE activated.
Input Req set for VALUE means this GDA-1600 channel reads the GDX-350’s monitored gas value. If the
Input Req menu is set for BATT this GDA-1600 channel reads the battery voltage from the GDX-350 with
the same Remote ID. To properly display battery voltage, the GDA-1600’s engineering unit range should
be 0-5.00 VDC. Even if this channel reads VALUE from the GDX-350, the battery voltage is displayed at
the bottom of this GDA-1600 menu as shown in Figure 5-12.

FIGURES 5-13 and 5-14 show correct settings for a GDA-400 base station to receive data from RF
GDX-350s.
