SeaI/O Manual 85
The (E1) and (E2) jumpers (shown in the orange boxes on the previous page) configure the D/A
outputs for 0-5V or 0-10V. Both channels can be configured independently. The D/A outputs
do not support negative voltages. You must also set the correct output voltage in your
application or MaxSSD. Refer to the SeaMAX Application Suite section of this manual for help
configuring software to work with the SeaI/O-470.
The A/D 10X gain (E3) jumper (shown in the green box on the previous page) is disabled at the
factory. Position the hardware jumper on both pins to enable this functionality, which allows
smaller voltages to be measured more accurately (e.g., a 0-1V input signal can be measured
more accurately by enabling the 10x hardware gain jumper and setting the SeaI/O-470 A/D
input channel for 0-10V range). You can also set the A/D input channel for 0-5V to sense
voltages smaller than 0.5V.
When the jumper is enabled, the “10X Hardware Gain” checkbox will also be enabled on the A/D
Inputs tab in MaxSSD. Refer to the SeaMAX Application Suite section of this manual for
information on using MaxSSD.
The (SW3) and (SW4) dipswitches (shown in the yellow box on the previous page) configure the
A/D inputs for current loop mode and are disabled at the factory. Since current loop mode is
differential, the corresponding dipswitch on both (SW3) and (SW4) should be properly set (e.g.,
„CH1‟ on both dipswitches needs to be set to „ON‟ to enable current loop mode).
SW3 – enables the current-loop sensing resistor
SW4 – ties the other half of connection to ground
