Digital Output Module BMT-DO4

1108861321

1. Description

The BACnet MS/ TP module with 4 digital outputs is designed for local s witching operations. It is suitable to operate elec trical components such as motors, contactors, lamps, sun -blinds etc. We recommend to protect the relay contact s additionally by a RC-element or high inductive loads. The module is prov ided with a manual control facility for manual switching of the relays. The output s can be op erated by standard objects via a BACnet- Client. Addressing of the module and baud rate s etting are done with the two address switches (x1 / x10) on the front. Possible set tings are addresses 00 to F9 and baud rates 9600 Bd, 19200 Bd, 38400 Bd, 57600 Bd, 768 00 Bd and 115200 Bd.

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 BTR NE TCOM 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
