Main module (on the upper

C connector)

• between 24 and 26

• between 30 and 32

Keying

Serial expander module (one

on the upper C and two on the

lower D connectors)

• between 16 and 18 (upper C connector)

• between 2 and 4 (lower D connector)

• between 16 and 18 (lower D connector)

This is an approximate value. See Chapter 2, Installing the Control Coprocessor, for instructions on calculating backplane current requirements.



With the 1771ĆDMC module (256 Kbyte), DF1 is not available on the communication ports; if you add an optional 1Ć or 4ĆMbyte SIMM, however,

the communication ports will initialize with DF1 capability.
