Turning On the Detector for the First Time
Connecting Remote Outputs
Thermo Scientific
To turn on the detector for the first time
1. Place the power switch at the front of the unit in the Off position (released or out
position).
2. Attach the power cord to the power entry module on the back panel of the detector and
connect it to the power source.
3. Turn the power on by pushing the power button in to engage it.
The Power LED turns solid green. If it does not light at all, see
"Troubleshooting."
If the Comm LED is flashing amber, the Surveyor PDA Plus Detector has been powered
up with the rotary switches set to 00. This setting is only appropriate for service
functions, such as downloading a firmware upgrade. For instructions on downloading
firmware, see
Appendix A, "Firmware."
detector off and use a small flat head screwdriver to reset the switches to an appropriate
value (01 to 99). See
stack ID to the rotary switch settings. After you reset the switches, turn the PDA detector
on for normal operation.
The Surveyor PDA Plus Detector has two remote outputs: READY and EVENT (see
Figure 11

13). The outputs are open collectors and are each capable of sinking
< 30 mA at 30 V dc, suitable for connecting to TTL and other families of ICs. In addition,
there is a 5 V output that supplies +5 V dc at 150 mA maximum that can be used for testing
digital input signals. When connecting to TTL inputs, a pull-up resistor (typically 10 k) is
required across the +5 V output and the open collector input connection if one is not built
into the external device.
The polarity settings (active high or active low) of these outputs must match those of the
inputs of connecting equipment.
If the switches have been set to 00, turn the PDA
