STATUS LEDS:

Power

„ON‟ when the device is connected to a sufficient power source and the power switch is

in the „l‟ (On) position.

Boot

During initial power up, the Boot light will be On to signal the first stage boot process.

When this has completed successfully, the Boot light will remain Off. If an internal

error is detected during this first stage boot process, this light will be blinking. Contact

Measurement Computing to arrange repair service.

Active

During initial power up, the Active light will be Off during the boot process, including

network configuration. The process will complete with a fast Blink, and then steady On

condition. With both the Power and Active lights On, the device is in the Ready state.

After this, the Active light will signal communications with a host computer at a slower

blink rate.

Data

The Data light will be On any time the device is acquiring channel data that is available

to the host PC control software.

Note:

After turning on the device, it can take up to 2 minutes to reach ready state, depending on

network settings. This can be monitored by the LED sequence:

Power Light On Boot Light On then Off Active Light Off, then Blinking, then On.

SYNC: Two “synchronization ports” provide a means of synchronizing units regard to pre-trigger data and post-

trigger scanning. Note that each 6000 Series device is capable of being designated as a Master Unit, Slave Unit, or

Terminating Slave Unit. The assignment is made in Encore. Refer to the following section, Synchronization, for

details. Refer to Accessories in the Specifications chapter for SYNC cables available from Measurement Computing.

Up to nine units can be synchronized. The total combined length of the SYNC cables is not

to exceed 2.438m (8 ft).

POWER INPUT: +19 VDC to +30 VDC, through a connector on the chassis. Power is typically supplied to the

device via a TR-60U, 24VDC universal power supply.

POWER SWITCH: A switch with a “0” label for Power Off, and a “ ” for Power On.

6224 User’s Manual General Information 1-3

Analog Circuitry

The 6224 is isolated from earth ground. However, the individual channels, within their four-channel group, are not

isolated from each other. The EX+, EX–, and T–signals are common among the four channels in their group as

indicated by note 1 on page 3-1 and in the block diagram (page 2-1).

You can connect the 6224 to a device that is biased at any voltage within the unit‟s rejection range of earth ground.

Synchronization

To synchronize from two to nine 6000 Series devices, link

them together with synchronization cables as indicated in the

example figure. Note that the first device (relative to the

circuit) will be the Master. The last device connected will be

the Terminating Slave. Thus the synchronized devices must

proceed sequentially from the Master to Terminating Slave, as

indicated in the figures. Note that channel-to-channel phase

relationships in a multi-device configuration are not

necessarily fixed. See notes below.

After physically linking the devices via the sync cables, they must still be configured as a “Synchronized Device

Group” in the Encore software. To do this, use the Synchronize Devices page of Encore‟s Hardware Setup tab.

Each Synchronized Group consists of one Master Device

and at least one Slave Device. By default, the first 6000

Series device added to the Synchronization Group will be

the Master and the last device added to the group will be the

Terminating Slave.

Encore‟s Synchronized Device Group Configuration

panel includes a pull-down list which allows you to select

the device that you want to have function as Master and the

one you want to function as Terminating Slave, should this

be different than the default settings.

Encore will display a Synchronization Error icon if it

detects that a necessary synch cable is missing or not

properly connected.

Up to nine units can be synchronized. The total combined length of the SYNC cables is not

to exceed 2.438m (8 ft).

Unplug sync cables from devices that are not intended to be part of a “Synchronized Device

Group.” Leaving a sync cable connected to an independent device can lead to errors.

Leaving an un-terminated sync cable on a synchronized device can lead to errors.

The sampled data phase relationship among channels between multiple devices is

dependent on the Channel Sync Skew specification for each device. When utilizing

different models in a multi-device system, any differences in the ADC filter delay

(“Input Delay”) should be added.

Reference Note: For detailed information refer to the Encore software‟s Comprehensive Help.

You can access the Help from within Encore. After doing so, navigate to the synchronization

related topic as follows from the Help‟s Contents panel:

Configuring Hardware>>Hardware Setup>>Synchronizing Devices.
