Crestron CNPI-48 48-Button Control Panel Interface

48-Button Control Panel
Interface: CNPI-48

Introduction

Currently there are two CNPI-48 configurations available. A configuration is defined

by either an "L" or "I" placed after the "CNPI-48" nomenclature. The CNPI-48L

drives LED indicators and the CNPI-48I drives incandescent indicators. Except

where noted, CNPI-48 is used to describe both configurations.

To determine the unit’s configuration, remove the front cover of the CNPI-48 which

is held in place by six hex screws. Towards the bottom of the circuit board there are

six IC sockets labeled RP15, RP16, RP17, RP18, RP19, and RP20. If the sockets

are populated by resistor packs (orange in color at the time of printing this

document), the unit is a CNPI-48L. If these sockets are populated with wire jumpers

in place, the unit is a CNPI-48I.

Features and Functions

• 48 digital inputs to accept contact closures from third-party switches

• 48 incandescent lamp (CNPI-48I) output drivers or 48 LED drivers

(CNPI-48L)

• Two bargraph outputs

The CNPI-48 allows third-party custom control panels to be interfaced to the

Cresnet

inputs to accept contact closures from third-party switches, 48 incandescent lamp

output drivers (for the CNPI-48I), 48 LED output drivers (for the CNPI-48L), and

two bargraph outputs.
