1. The CS485 may be used in point to point applications as well as multi drop applications using either 4 wire ot 2 wire configurations Up to 32 devices may be connected together on one communication line The CS485 has 1500 volt optical isolation between the RS 232 side and the RS 485 side The RS 485 lines are protected with 2 stages of surge protection and jumpers allow complete configuration of terminating and pull up down functions Configuring the CS485 The full manual for the CS 485 is available on the Centaurus Prime web site www centaurusprime com While it is very lengthy and technical we recommend that you download and review the full manual if you are using the Gateway in unusual applications e g with radio modems Ethernet converters line drivers with delays etc The CS 485 allows for many options and a unique data mode that no other RS 485 converter on the market has It is extremely robust and adaptable The CS485 s default configuration is for 2 wire RS485 Following are setup parameters for RS485 2 wire RS422 4 wire and optionally RS232 _RS 485 RX and TX Jumpers J4 Enable pull up resistor for RX line J3 Enable pull down resistor for RX line J2 Terminate RX pair with 120 ohm resistor J7 Enable pull up resistor for the TX line J6 Enable pull down resistor for the TX line J5 Terminate TX pair with 120 ohm resistor J8 IN Enables 2 wire operation for both2. 1 2012 VERSION 1 3 Centaurus Prime CENTAURUS PRIME Integrations Custom Programming Consulting p 1 22 Gateway Guide 1 2012 VERSION 1 3 INTEGRATIONS CUSTOM PROGRAMMING AND CONSULTING P1 Gateway Guide 2006 by Centaurus Prime 4425 Cass Street Suites B C San Diego CA Phone 858 270 4452 Fax 858 273 7769 www centaurusprime com Table of Contents Introduction i CHAPTER 1 m Gateway Installation Basic Information Summary Single Board Computer Basics O N Connecting Power to the Gateway Connecting Siemens P1 Trunks to the Gateway Connecting To the Modbus Master Configuring the CS485 RS485 Communications RS422 Communications RS232 Communications Note about Removing the CS485 Connecting to a BACnet IP Network N nN OO OAG BE Gateway Overview and Identification CHAPTER 2 Commissioning the Gateway with the Local user Interface 9 Creating and Downloading the GATEWAY INI file 10 Creating and Downloading the SOCKET CFG File 11 Local Mode Menu Options 11 Auto Discovery and Database Generation 12 Summary Menu Options 14 Devices Menu Options Point Menu Options Control Menu Options Watch Menu Options Uploading and Downloading files to the Gateway Setting Up The Modbus Driver Setting Up The BACnet System TEMPLATE Files index 15 17 20 24 25 26 27 28 32 CENTAURUS PRIME Ci Gateway Installation B

16. that number so that the BACnet instance numbers of the devices are all prefixed by the network number As an example if you set the BACNET NETWORK number to 333 and the BACNET OFFSET to 333000 then you would end up with BACnet device numbers 333001 333002 333003 etc on network 333 Makes it simple no Just a suggestion DO NOT over tax the BACnet network At about 30 BACnet IP packets pet second directed TO THE GATEWAY the Gateway will saturate any more packets than that and they are lost Any more than that will cause retries and actually SLOW DOWN the BACnet system This is because BACnet IP is a connectionless system the requestor sends a packet to the Gateway and the network gives it a best effort to deliver it If the network is saturated and our Gateway does not receive the packet the requestor has to time out and then retries its request packet This may mean that control logic will stall depending upon the software implementation in the controller until that retry occuts TEMPLATE Files You need to download to the Gateway and regular and custom templates that will be used in your building Say that you had a system with a couple DPUs and many TECs Perhaps you have several VAV box types like this e Many Application 2021 TECs cooling only VAV for internal zones e Many Application 2022 TECs VAVs with baseboard or electric reaheat e Afew 2051 TECs Blower coils e One Application 238

44. to the Modbus Master is done one of two ways 1 Ethernet If you have ordered the P1 Gateway as the standard Modbus IP configuration then it is simple You plug in an 8 pin Category 5 ot Categoty 6 cable into the Ethernet connection on the top right hand corner of the PC You must set the IP address of the Gateway to a static fixed address on the segment that you are in This is done with the CONFIG TXT file described in the next chapter 2 Serial Link If you have ordered the P1 Gateway with the Modbus RTU protocol option then the Modbus connection is made with the CS485 line driver included in the Gateway cabinet if the product has been ordered with a Modbus RTU front end The CS485 line driver is an RS 232 to RS 485 interface converter It allows an RS 232 device to reliably transmit data over long distances up to 4000 feet The CS485 has many features not normally found in typical line drivers and is intended for operation in harsh industrial environments You must also modify the GATEWAY INI file to specify the baud rate and parity of the Modbus RTU connection All Centaurus Prime Gateways act as a seties of Modbus slaves and can be a large number of logical devices but it acts as only one electrical device on the Modbus RTU trunk The P1 Gateway can act at any baud rate from 4800 baud to 19200 baud 19200 baud is not recommended except for vety short distances Even Odd and None are the valid patity options
