Addressing Serial Sensors
When connecting to a Detcon Model 600 or Model 700 Series sensor, the addressing procedure is different.
First, note how the gas sensors are addressed. Normally, addresses start from 01 and count up. An example is
shown below to explain the procedure. To address four gas sensors (01-04), set the following:
CH #
Device Address
01 01 00
02 02 00
03 03 00
04 04 00
NOTE: the CH# is the gas channel number displayed on the Main Display. The Device # is the serial ID
address set at the 600 or 700 Series sensor. The Address # is always set to “00” which tells the
1600/6400 controller to expect the serial data in the 600 or 700 Series Sensor format.
NOTE: The 1600/6400 Device # is in decimal format, and the serial address switch setting for the 600 or
700 Series Sensor are in hexadecimal format. This means that device number 10 decimal on the
1600/6400 corresponds to the 600 or 700 Series Sensor at address 0A hexadecimal.
When a 600 or 700 Series Sensor is used, the “Scaling Factor” may need to be adjusted. The scaling factor is
an entry that resides just below the main entry points of the “Set Gas Type and Range” menu (Figure 21)
discussed in Section 5.3.3. The scaling factor is used to adjust the decimal point in the reporting of the
sensor’s reading range. Use the X1 scale if there are no decimal point adjustments needed. The 600 or 700
Series Sensor’s reading format is always in ### format. To properly display a 0-10.0ppm range, the X10
scaling factor must be used.
Addressing Model 10 and Model 12 Control Cards
When connecting to a Detcon Model 10 or Model 12 Control Card, the addressing procedure is different. Note
how the control cards are addressed. Normally addresses start at 01 and count up. When addressing the
Detcon Model 10 or 12 Control Cards, the address is set to 05 to notify to the 1600/6400 controller that it is
addressing a Model 10 or 12 Control Card. An example is shown below to explain the procedure. To address
four Model 10 or 12 Control Cards, set the following:
CH #
Device Address
01 01 05
02 02 05
03 03 05
04 04 05
NOTE: the address is always set to 05. This signals the 6400 controller to accept the serial data in the
Model 10 or 12 Control Card format.
NOTE: The 1600/6400’s device # is in decimal format, and the address switch setting for the Model 10
or 12 Control Cards are in hexadecimal format. This means that device number 10 decimal on the Model
6400 corresponds to the Model 10 or 12 Control Card at address 0A hexadecimal.
When a Model 10 or Model 12 Control Card is used, the “Scaling Factor” may need to be adjusted. The
scaling factor is an entry that resides just below the main entry points of the “Set Gas Type and Range” menu
(Figure 21) discussed in Section 5.3.3. The scaling factor is used to adjust the decimal point in the reporting of
the sensor’s reading range. Use the X1 scale if there are no decimal point adjustments needed. The Model 10
