The PAM-TRX is designed to transmit the TTL RS-232 data packet from the dosimeter when the

DMC-2000 is configured with transmission ON, 4800 BAUD, Triggered. The unit is compatible

with all the DMC family gamma dosimeters data formats (DMC2000S, X and SOR/R).

Preparation for use:

2.1.2.1 To open the back case: remove the locking screw and slide off the battery cover. Remove

the battery (if installed) and then slide off the case back.

2.1.2.2 The dosimeter must be installed with the display towards the top window face down and

dosimeter clip removed. Once inserted, replace the back cover by sliding it up, ensuring

the dosimeter is properly seated and aligned with the ISO connector.

2.1.2.3 Ensure dipswitch settings are configured with all the desired options correctly selected.

See Section 2.1.3 for detailed configuration.

2.1.2.4 Install a new ‘AA’ 1.5 V alkaline battery. Replace the battery cover and secure with the

locking screw. Do not overtighten the locking screw

. MGPI recommends using only

Duracell or Energizer brand batteries for best performance.

>> See Figure 1 for PAM-TRX part identification.

2.1.2.5 Turn the dosimeter ON. Note one single flash from the green led will indicate that the

battery, dosimeter and the radio are functioning properly. After one or two short alarm

cycles (while the low battery detector charges up), the PAM-TRX audibly chirp. At this

point, the green LED will flash at an interval defined by the radio configuration, typically

four (4) seconds. The radio is normally in a “sleep mode” to reduce power consumption.

When the radio “wakes up,” it turns on the PAM-TRX power supply. The alarm circuits

are enabled at all times. Pressing the alarm test button or running a magnet by the case side

(internal reed switch and if the option is enabled) will turn ON the power supply and trigger

all enabled alarms.

2.1.2.6 If the dosimeter alarms (dose or dose rate alarm), the enabled alarm functions in the

PAM-TRX will be triggered (buzzer, vibrator, LED).

2.1.2.7 The alarm can be tested at any time by pressing a test push button accessible through a

small hole in the back of the case or by proximity to a magnet by the side of the case if

this function is enabled (Figure 2 below).
