Important Connection Instructions (XY2-100 Interface
Please wear an ESD strap when performing these steps.
STEP 1: Connect Power Cable

Make sure that the connectors are firmlyseated and the two side screws areconnected securely.
A flathead screwdriver may be useful tofully engage the screws.

1. Make sure your power supply meets the following requirements.

LightningTM II Electrical Specifications
Input Voltage

48 ± 2V DC, Single Power Supply

Power Requirements

6A Peak, 3A RMS per axis

Apply power to the scan head. You should see the red LED on each servo board blink
twice and then flicker at high frequency. The galvos should seek their home positions
and be ready to follow commands within 5 seconds.

2. Find the power cable in your shipping package. Connect the color-coded wires ofthe power cable to the power supply as shown at the left side of Figure 1. Make surethat the GND (White) and 0V (Black) are tied to the Chassis Ground (Green) at thepower supply end as shown in Figure 1.

Make sure that the X-axis galvo connects toX-axis servo, Y-axis galvo connects to Y-axis[and for 3-Axis Scan Head that the Z-axis galvo
connects to the Z axis]. Note that the labels onthe galvo cables match labels on thecorresponding servo board connectors.

3. Connect the daisy-chained power connectors at the other end of the power cableto the servo boards and fan in the order shown at the right side of Figure 1. Make
sure that the first connector in the chain goes to the X-Servo and the last connector
goes to the fan.

STEP 4: Verify Proper Grounding
Before connecting your controller to the LIGHTNING II scan head, complete thefollowing:
1. With the LIGHTNING II servo boards and your controller powered on, and yourXY2-100 cable plugged into your controller only, measure the voltage difference
between the servo chassis ground (A) and your XY2-100 cable DB25 (B) connector
shell. The voltage should be less than 0.3V. This verifies that your controller isproperly grounded to the chassis. If you measure >0.3V, do NOT connect XY2-100
cable and contact us. See Figure 5.

2. Make a power cable with a DB9 female connector based on the pin assignments
shown below. Make sure that the GND (White) and 0V (Black) are tied to the Chassis
Ground at the power supply end as shown in Figure 2.

3. Connect your controller to the XY2-100 interface board via your XY2-100 cable.
The XY2-100 interface board is at the bottom of the LIGHTNING II servo boardstack.
