Introduction The Cerban Splitter CBS-3 accepts in input a serial line on which data are transmitted using Cerban protocol and outputs the signal to two serial lines with the same protocol. The Cerban Splitter CBS-3 is composed by one CPU board to which is connected an asynchronous board with four communication lines.
Product description The CPU board The CPU board (Fig. 1) is the only board that composes the Cerban Splitter CBS-3. service pin LED Neuron Reset Chip Flash EPROM Service Diagnostic UART UART1 UART2 UART3 UART UART4 Fig. 1 The CPU board On this board there are: §...
In the lower right corner of the connection board there is the power supply block with two pins marked + and -. You must connect here the voltage source (10 to 30 V d.c.). Fig. 2 The connection board Siemens Building Technologies e1148c Cerberus Division...
The network configuration of CBS-3 The Cerban Splitter CBS-3 is inserted in the network configuration shown in Fig. 2.4. It allows to connect any device which uses the Cerban protocol to two independent serial lines. The two lines can be connected to any device able to understand the Cerban protocol.
CBS-3. For instance, a CS11 requires the (OFF, OFF, ON) setting. Then, using the Tab. 3 , find out the dip-switches that are used by the UART to which the subsystem is connected; set the three dip-switches as specified. Siemens Building Technologies e1148c Cerberus Division 06.2000...
Even if the Flash EPROM configuration is enabled, you must set the communication baud rate with subsystems using the dip-switches and according to the suggested pro- tocol/baud rates (See section 6). Siemens Building Technologies e1148c Cerberus Division 06.2000...
The gateway GW-21 is powered using the connector located on the connection board (Please refer to Fig. 2). Please pay attention to pin polarities. The supply voltage must be in the range 10 to 30 V d.c. Siemens Building Technologies e1148c Cerberus Division...
Cables and connections Connection to GW-20 The figure below shows how to connect the Cerban Splitter CBS-3 to the Gat eway GW- 20, to transmit messages to the CMS/LMS monitoring system. Only UARTs 3 and 4 can be connected to the Gateway.
