V77 Pinout

The V77 ADM-1 is installed in the M Series chassis as described in the installation

section of this manual.

NOTE: The V77 ADM-1 cannot be installed as Module 1. If a V77 ADM-1

is removed from a module slot and a different V77 ADM-1 is installed in

that location, the newly installed module acquires the previous module's

configuration. Moving a V77 ADM-1 to a different module location

requires reconfiguration because the configuration parameters are stored as a

function of slot location and module type. The configuration information

does not stay with a relocated module.

IMPORTANT: You must install jumper JP1 to use +10V range. First,

remove the ADM-1 from the M Series chassis. Next, locate JP1 in Appendix

B and install a jumper connector on JP1.

Once the ADM-1 has been installed in the M Series chassis, connect a cable with a

DB-25 male connector to the input connector, J2. Determine if you will be using

single-ended or differential inputs. Singled-ended operation allows up to 16 inputs

using grounds of the same potential. Differential operation allows up to 8 inputs

using different reference polarities. Configure your input cable as shown below for

single-ended operation or for differential operation.
