SCU Controller Board (Version 5)

Item Number 545-432-05 Page 1 of 4

Product Description

The SCU V5 controller board (Figure 1) is available

in seven configurations: six APOGEE and one pre-

APOGEE.

The controller board has two man-machine interface

(MMI) ports: the MMI and the MMI MODEM. Each

port comes with a quick-connect, RJ-11 jack. Use

these ports to connect to an operator terminal,

printer, or a modem approved by Siemens Building

Technologies.

The memory board slides into the controller board

bracket. The memory board’s flash read-only

memory (ROM) contains the firmware that controls

the SCU controller board.

The point board is positioned beneath the controller

board by standoffs. A ribbon cable electrically

connects the two boards. The point board contains

circuitry to connect to analog input (Al), analog

output (AO), digital input (DI), and digital output (DO)

points.

APOGEE Assemblies

Two-board Assembly (8 MB or 6 MB)

The APOGEE two-board assembly is used when

replacing existing pre-APOGEE V4 controllers. It

consists of the following components (Figure 1):

• SCU V5 controller board

• Memory board (8 MB or 6 MB total memory)

with 2.x firmware

Three-board Assembly (8 MB or 6 MB)

The APOGEE three-board assembly is used when

replacing existing pre-APOGEE V3 or earlier

controller boards with APOGEE V5. It consists of the

following components (Figure 1):

• SCU V5 controller board

• Memory board (8 MB or 6 MB total memory)

with 2.x firmware

• V4 point board

Pre-APOGEE Assembly

The pre-APOGEE three-board assembly is used

when replacing existing V3 or earlier controller

boards without upgrading to APOGEE firmware. It

consists of the following components (Figure 1):

• SCU V5 controller board

• Memory board (3 MB total memory) with 12.51

firmware
