Analog output characteristics for
AO2 (pin 19) and AO1 (pin 20)
Defines current (0–20 mA) or voltage (0–10 V) for analog output 1 and 2.
By default, current (0–20 mA) is selected using jumpers 1 and 2 and registers 4008 and 4028 contain
a value of 2.
To select voltage (0–10 V) for output Aout1, set jumper 1 in the voltage position (V) and set Modbus
register 4008 on the I/O board (SID 200) to 3.
To select voltage (0–10 V) for output Aout2, set jumper 2 in the voltage position (V) and set Modbus
register 4028 on the I/O board (SID 200) to 3.
5.6 Applying Power
Apply power to the DXM100/1000-Bx Wireless Controller using either 12 to 30 V DC or a 12 V DC solar panel and 12 V
sealed lead acid battery operating together.
The DXM100 has three power input and three power output options:
•
Input Power:
◦
12 to 30 V dc
◦
12 to 30 V dc solar panel
◦
12 V dc sealed lead acid battery with automatic charging
•
Courtesy Output Power Supplies:
◦
One 5 V dc fixed
◦
Two 5 V dc or 16 V dc (DXM100-B1 models) or Two 5 V to 24 V dc (DXM100-B2 models)
The DXM continuously monitors the health of the power inputs. If a power input fault is detected, the DXM automatically
switches over to battery with continuous uninterrupted operation.
If the incoming voltage drops below 11.2 V dc, the cellular modem does not turn on and will not turn on until the voltage is
above 11.8 V dc. A text file (CmVMon.txt) on the internal micro SD card saves the periodic sampling of the incoming voltage.
If cellular operation stops because of voltage, it is logged in this file.
Pin
Description
Pin 1
No connection
Pin 2
12 to 30 V DC input (+) or solar panel connection (+)
Pins 3, 5, 8, 17, 26, 29
Main logic ground for the DXM100/1000-Bx Wireless Controller
Pin 4
Solar or backup battery positive input. Battery voltage must be less than 15 V dc. Use only a sealed lead acid (SLA)
battery.
5.6.1 Connecting a Battery
When attaching a battery to the DXM as a backup battery or as a solar battery, verify the charging algorithm is set properly.
The factory default setting for the battery charging algorithm assumes you are using 12 to 30 V DC to recharge the battery.
The charging algorithm is designed to work with a sealed lead acid (SLA) battery only.
•
When using 12 to 30 V DC, connect the 12 to 30 V DC + to pin 2 and connect the ground to pin 3.
•
When using main dc power with a back up battery (default configuration), connect the incoming main power pin 2 (+)
and to pin 3 (-). Connect the 12 V sealed lead acid battery to pin 4 (+) and pin 5 (-). The incoming main power must
be 15 to 30 V dc to charge the battery.
5.6.2 Supplying Power from a Solar Panel
To power the DXM100/1000-Bx Wireless Controller from a 12 V dc solar panel, connect the solar panel to power pins 2(+)
and 3(-). Connect a 12 V dc sealed lead acid (SLA) rechargeable battery to pins 4(+) and 5(-).
The factory default setting for the battery charging configuration assumes you are using 12 to 30 V DC power to recharge the
battery. If the incoming power is from a solar panel, you must change the charging configuration.
The battery charging configuration defaults to a battery backup configuration. To change the charging configuration from the
menu system:
1. From the DXM LCD menu, navigate to
System Config
>
I/O Board
>
Charger
.
2. Select
Solar
for solar panel configurations or
DC
for battery backup configurations.
To change the charging configuration by writing to Modbus register 6071 on the I/O base board (Slave ID 200):
