OM2  10
ASSEMBLY STEPS
First we’ll install the components that are common to all configurations of your
OM2. Then the components that are configuration specific will be installed.
Make sure to save at least 2 of the resistor leads trimmed off the resistors for
use as jumpers later on.
 1. Install OC1, optical isolator marked SFH620A. Make sure the small
dot near one corner on the device matches the dot printed on the board
outside the OC1 outline.
 2. Install R3, 10K [brown-black-orange]
 3. Install R4, 10K [brown-black-orange]
 4. Install R5, 10K [brown-black-orange]
 5. Install R6, 1K [brown-black-red]
 6. Install R7, 1K [brown-black-red]
 7. Install R8, 10 ohm [brown-black-black]
The white band on the component MUST match the white band on the circuit
board for D1 and D2.
 8. Install D1, 1N4002 [1N4002]
 9. Install D2, 1N4002 [1N4002]
The following terminals are installed so the openings on the housing are
facing the edge of the board.
 10. Install J1, 2 position screw terminal
 11. Install J3, 2 position screw terminal
 12. Install J4, 2 position screw terminal
 13. Install J2, 3 position screw terminal
