M4-LHS installation and Operation Manual
Connecting to BaCnet interface Module
• The M4-LHS can communicate to BACnet MSTP networks when used the X-BAC BACnet Interface Module (CA009100). The
module must be purchased separately.
• The BACnet Interface Module comes with an RJ45 cable.
• Both the M4-LHS and the BACnet Interface Module are equipped with a RJ45 socket (RS485) to connect to communicate to each
other.
• The Interface BACnet Module must be wired to the BACnet MSTP network using the RS485 terminals A, GND, and B.
• If both an extension panel and the BACnet Interface Module are to be used, connect the RJ11 socket on the BACnet Interface
Module to the extension.
• Set the BACnet parameters. See "BACnet MSTP Communication Menu" on page 26.

aCTiVaTE THE BaTTErY
• The battery enables to control to maintain the clock time.
• Unscrew and remove the Enclosure Display Module to reveal the back of the control
CPU Board.
• Remove the plastic strap that covers the battery. The battery holder contacts should be
touching the battery. The control has a coin Lithium battery (CR2032) that is used to
maintain the control's time during power outages. This battery can maintain the clock for
up to a total of 100 days.
aLErT
Do not install the battery unless you plan to keep the control continuously powered. If the
control has no power, the battery will lose its charge in 100 days.
