Description

Use the Model 8503 DIN to BNC Trigger Cable to connect the Model 2000 Multimeter with an y instrument having BNC trigger
connectors rather than micro DIN trigger connectors. One end of the Model 8503 is an 8-pin micro DIN connector, to be con­nected to the Model 2000 Multimeter. The other end is split into tw o BNC connectors, one being specified as the connector for
VMC, or Voltmeter Complete (output), and the other being specified as the connector for EXT TRIG, or External Trigger (in­put).

In its factory configuration, the trigger link connector for the Model 2000 is wired so that only pins 1 and 2 are functional. Pin
1 is used for the VMC output, while pin 2 is for the EXT TRIG input.

The Model 8503 is 1 meter long and is depicted in Figure 1. Figure 2 shows the pinout for the Model 2000 rear panel trigger
link connector.
