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.
