ATTENTION COULD DAMAGE INSTRUMENT AND VOID WARRANTY
Printed Circuit Assemblies (PCAs) are sensitive to electro-static
discharges too small to be felt by the human nervous system. Failure to
use ESD protection when working with electronic assemblies will void
the instrument warranty. Refer to Section 13 for more information on
preventing ESD damage.
To install shunt in the last analyzer:
1. With NO power to the instrument, remove its top cover and lay the rear panel
open for access to the multidrop PCA, which is seated on the CPU.
2. On the multidrop PCA’s JP2 connector, use the shunt provided to jumper Pins
21  22 as indicated in (Figure 3-14).

Note: If you are adding an instrument to the end of a previously configured chain,
remove the shunt between Pins 21
 22 of JP2 on the Multidrop/LVDS PCA in the
instrument that was previously the last instrument in the chain.
