CAUTION:
WARNING:
Datamate Software
Datamate is a customer software tool for all controller communications. There are
two versions: Datamate Base, and Datamate Advanced. Datamate Base works on an
IBM-compatible Personal Computer (PC), or a Handheld PC or Pocket PC™ running
Windows CE. Datamate Advanced works only on an IBM-compatible Personal
Computer. With Datamate, you can backup, restore, and edit any APOGEE database
(but only Datamate Advanced allows you to edit points offline). Backing up and
restoring a database can be accomplished while connected to any APOGEE field
panel, or to the Building Level Network (BLN) or Floor Level Network (FLN) device in
question. A modem and telephone lines can also be used. Databases can be saved
to a hard or floppy disk and kept for permanent storage or used as backup.
For more information on Datamate software, refer to the appropriate user guide
based on which version of Datamate you are using (Base or Advanced), or contact
your local Siemens Building Technologies, Inc. representative.
Getting Help
Indicates that equipment damage or loss of data may occur
if the user does not follow a procedure as specified.
Indicates that personal injury or loss of life may occur to the
user if a procedure is not performed as specified.
If at any time you find that you need help with a Laboratory Room Controller issue
not covered in this manual, contact your local Siemens Building Technologies, Inc.
representative.

Hardware Outputs
Product Overview
Analog
• AO-E/AO-P module (Floating Control)
• Operator Display Panel (ODP)
• AO2 (Flow Signal, 1 to 10 Vdc)
Digital
• FLN communications trunk
• DO3 (24 Vac, Alarm/Hi.Low Output)
Power Wiring
The controller is powered by 24 Vac. Power wiring connects to the three screw terminals on
the controller labeled “C” (Common), “H” (Hot) and “E” (Ground) on the terminal block labeled
“TB1”. Earth ground connection is required (Figure 2).
Communication Wiring
The controller connects to the field panel by means of a Field Level Network (FLN) trunk.
Communication wiring connects to the three screw terminals on the controller labeled “+”
(positive), “-“ (negative), and “S” (Shield) (Figure 3).
