Verify that the OEM DAQ board is properly connected
Ensure that the header pins on the OEM DAQ board are properly connected to the OEM header connectors on
the baseboard. Orient the OEM DAQ board so the USB/Ethernet cables connect to the OEM DAQ board at the
left edge of the baseboard. Refer to the
Cable Entry board label for proper orientation.
5. Attach the supplied PC interface cable to the OEM DAQ board; perform one of the following steps:
o Attach the USB cable to a USB-1608G-OEM Series board and the computer or self-powered hub.
o Attach the CAT-6 Ethernet cable to the E-1608-OEM board.
Installing 8B analog I/O modules
You can install up to eight 8B analog input modules into the baseboard mounting locations labeled CH0 to CH7 ,
and two analog input or analog output modules into mounting locations labeled CH8 and CH9 . When using a
product with analog outputs you must install an output module in CH8/CH9. When using a product without
analog outputs you can install a voltage input module into CH8/CH9.
Power down the baseboard whenever you install or remove 8B analog I/O modules
Make sure the power switch SW1 is OFF before you install or remove 8B modules.
Each 8B analog input module ( CH0 to CH7 ) has dedicated positive (+) and negative (–) inputs, along with
positive (+) and negative (–) excitation inputs. Each 8B output module has dedicated positive (+) and negative
(–) outputs. All signals are brought out to screw terminals for field wiring connections. When using CH8 and
CH9 with 8B input modules installed, note that there are no associated ± excitation pins.
Perform the following steps to install 8B analog I/O modules:
1. Turn the baseboard power switch SW1 OFF.
2. Align the 8B module retaining screw and pins with the holes on the circuit board.
3. Gently press the module into place.
4. Tighten the retaining screw; do not over-tighten.
5. Repeat these steps to install additional 8B analog I/O modules.
Configuring for ten 8B analog input modules
8B analog I/O mounting locations CH8 and CH9 are configured by default for output. When connected to a
board without analog output functionality, such as the USB-1608G-OEM or USB-1608GX-OEM, these
locations can be converted to 8B analog input modules via onboard jumpers. Refer to
8B analog I/O module
control jumpers on page 19 for more information.
Configuring 8B analog I/O modules
Onboard jumpers let you enable CJC for thermocouple input modules, convert the analog output module
locations to input, and scale the OEM DAQ analog output channel voltage to ±5V to match the voltage range
output by an installed 8B analog output module. Refer to
8B analog I/O module control jumpers on page 19 for
details about how to use the 8B module control jumpers.
Installing SSR digital I/O modules
You can install up to eight digital I/O modules into the mounting locations labeled SSR0 to SSR7 . Each
location can be set for either input or output with the DIP switch labeled SW2 .
Power down the baseboard whenever you install or remove a digital I/O module
Make sure the power switch SW1 is OFF before you install or remove an SSR module.
Mounting screw threads are provided to easily install the SSR modules. SSR modules use a standard color
scheme so you can quickly identify what module type is installed. Positive (+) and negative (–) relay contacts
are brought out to screw terminals for field wiring connections. Each SSR module has an associated LED that
turns on when the module output state is active.
