CONTENTS INTRODUCTION CONNECTING THE LINK ADAPTOR TO THE SMUS SYNCHRONISING 2 SMUS DIO EXPANDER TEST BRIDGE SMU Symbols The following symbols are displayed on the instrument and throughout the manual, to ensure the safety of the user and the instrument, all information must be read before proceeding. CAUTION Indicates a hazard that could damage the product that may result in loss of important data or invalidation of the warranty.
For use with the SMU4000 Product Series: SMU4001 & SMU4201 This SMU Link Adaptor is designed to connect two Aim-TTi SMUs together via the DIO terminal ports on the rear panel. It can also be used as a DIO Expander for one or two instruments, removing the need to wire each DIO terminal individually.
2. CONNECTING THE LINK ADAPTOR TO THE SMUS The Link Adaptor mates with standard 10W (2 x 5 DIL) female 2.54mm pitch IDC ribbon cable. Connecting to the SMU Image for illustration purposes only. Strain relief has been added to the SMU connection end of the ribbon cable to allow the cable to be removed without damaging the cable.
3. SYNCHRONISING 2 SMUS A fully functioning two channel SMU can be created with two SMUs via a handshake triggering system using the Link Adaptor to connect the trigger DIO lines. NOTE When using the Link adaptor to connect two SMUs, the adaptor internally connects the ‘Trigger In’...

If both sets of results are intended to be plotted on one graph, the total number of measurements on both SMUs must match. To maintain synchronisation, set the same number of levels/ shapes on both SMUs. See the SMU4000 Series Instruction Manual for more details. SMU Link Adaptor Instruction Manual...
4. DIO EXPANDER As well as connecting 2 SMUs together, the SMU Link Adaptor can be used with a single SMU as a DIO expander- removing the need to wire each DIO terminal individually. SMU-1 / SMU-2 The DIO terminal connections detailed in this section can be used for up to two SMUs via the SMU-1 and SMU-2 connections.

+5V / 0V These lines are provided for powering external control circuitry. The 5V supply is internally fused (resettable fuse) to 500mA. DIO 2-6 (General) DIO configuration is exclusively for use with sequence mode. Used for triggering input and output events from within a sequence, allowing a defined sequence to control or be controlled by external circuitry.

Input / Output CNFG > [System] Interfaces > [DIO] Configure Each DIO line can be configured as an Input or an Output from the SMU. CAUTION 5.25Vpk Max input voltage. Always use shrouded ferrules to prevent the risk of shock. Input levels: Input allows an external device to control the state of the line.
5. TEST BRIDGE SMU Test Bridge SMU simplifies the test setup when using multiple instruments allowing the complete control of one or two instruments from one place. This program also provides advanced graphing features which enable results from multiple SMUs to be plotted on a single graph, including options to split the data into steps and repeats for further analysis.
