Installing the enhanced serial data interface card

Introduction

Each enhanced serial data interface (ESDI) card has two ports

on the faceplate, J1 and J2, to which you can connect the AML

cable. You assign each port a device number (DNUM), which

you use to establish the software link with Meridian Mail. (This

is explained in Chapter 12, “Configuring the Meridian 1.”)

There are two important criteria to consider when you

determine and program the DNUMs for the ESDI card:

• The two numbers must be consecutive.

• The lower number must be even.

You select DNUMs on the ESDI card by setting SW2. The

maximum possible number of devices on the Meridian 1 is 16.

See the following table.

Note: You must assign the even number of the pair to the J1 port

of the ESDI card. You then assign the odd number to the J2 port.

You need a vintage H ESDI card. Be sure to use the correct

switch option settings required for this card.

Note: In the Meridian 1 documentation (Circuit Card

Installation [NTP 553-3001-211]), this vintage of card is

referred to as a “Style B” card.
