Introduction

The 6222 is a twelve-channel, 24-bit resolution thermocouple input module device that connects to a host PC‟s
Ethernet port (directly or via a network hub/switch) and can be synchronized with other 6000 series devices.

Up to twelve thermocouple inputs can be connected to each unit via front panel removable screw-terminal
connectors. Each of the channels has a TC+ and TC- connection.

As indicated by the block diagram in chapter 2, the 6222 contains three internal modules. Each supports four
thermocouple channels; and each module has a common terminal (COM) that is internally connected to an isolated
ground reference. Within a module channel to channel can be within 1.5V of each other and within 250V to ground
and within 250V to one of the other two modules.

The hardware provides the signal conditioning and acquisition engine, and the software defines the specific
configuration and analysis aspects of the system.

Front Panel

The front panel is populated with three removable screw-terminal connectors. Each of these connectors contains 10
terminals to support COM and three thermocouple channels. Each channel has two connection points, the odd
numbered terminals are the negative (-) input and the even numbered terminals are positive (+). Additional
information is included in chapters 3 and 8. Note that connector backshells can be fitted over the terminal­connectors to protect them and the associated thermocouple connections. Backshells are discussed further on
page 1-3.

Rear Panel

Channel Designation on the 6222 Front Panel

The following items reside on the rear panel, from left to right: 1st cable tie mount, Ethernet jack, DB9­Digital I/O port, 2nd cable tie mount, #6-32 chassis ground screw, four status LEDs, two synchronization
jacks, a power input jack, and a power switch. A description of each follows.

6222 User’s Manual General Information 1-1

When connecting the unit directly to a PC (i.e., when not connecting to a network
hub) you will need to use an Ethernet crossover cable.

Ethernet cable length must be <3 m (9.8 ft) in order for the system to be CE
Compliant.

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.

Up to nine units can be synchronized. The total combined length of the SYNC cables is not
to exceed 2.438m (8 ft).

CABLE TIE MOUNTS: Two cable tie mounts are present to provide for strain relief of cables.

ETHERNET: The 10/100BaseT Ethernet port can connect to the Ethernet port of the host PC, or to an

Ethernet network. The Ethernet connector has two built in LEDs that indicate traffic flow on the network.
Refer to Accessories in the Specifications chapter for Ethernet cables available from Measurement
Computing.

DIGITAL I/O: Eight digital I/O lines are accessible via a 9-pin, female DSub connector. Additional
information is included in chapter 8.

GROUND (#6-32): Provides a connection point for Chassis Ground via use of a #6-32 machine screw.

STATUS LEDS:

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.

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.

Connector Backshell (2 views)

Using a Ferrule

Connector Backshells and Ferrules

Connector backshells are optional protective casings that can be fitted onto the 6222 removable screw-terminal
connectors. The backshells provide a thermal shield to reduce the effect of short term ambient temperature changes,
and to ensure the accuracy of the cold junction measurement. They also provide mechanical relief and protection for
the TC wires and screw terminal connections.

Accuracy specifications are only valid when using provided connectors and properly installed backshells.

Terminating thermocouple wires with ferrules will also help maintain good connections in vibration applications,
but unless a backshell is used, there will be no protection to the screw-terminal connectors or to the wires at the
point of connection.

Each 6222 is shipped with three screw-terminal connectors and three backshells. Extra connector/backshell kits can
be ordered from the factory. Each kit contains one connector and one backshell.
