Digital Input Module
BMT-DI10
1108811319
1. Description
The BACnet MS/TP module with 10 digital inputs was developed for
decentralized switching tasks. It is suitable for detecting potential-free
switch states, for example electrical limit switches on vent valves or auxiliary contacts of power contactors. The inputs can be used as contact
or voltage inputs. The inputs can be scanned by means of standard
objects via a BACnet client. The module is addressed and the baud
rate is set by means of two address switches on the front.
Suitable for decentralized mounting in serial sub-distributor.
2. Declaration of Conformity
The device was tested according to the applic able st andards. Conformit y was proofed. The declaration of conformit y is available at
the manufacturer METZ CONNECT GmbH.

7. Network adress and Bit rate setting
Configuration Switches
Hexadecimal Switches x10, x1 define the Network Address
(00 - F9; e.g. F9h = 15x16+9 = 249d) and Baud rate (FA – FF).
• Turn Switch x10 to E (Device is temporaryly configured as Slave)
• Turn Switch x1 to A – F to select Baud rate
• Turn Switch x10 to F, wait 1 second
• Red and green LEDs are blinking when Baud rate ist stored in
EEPROM
• Turn Switch x10 to select Network Address
• Turn Switch x1 to select Network Address
MS/ TP Master if using Network Address 0x00 … Max_Master,
MS/ TP Slave if using Network Address Max_Master + 1 … 0xF9.
