1. Product Specifications The Raypak Gateway card is a hardware product designed to be a communications front end for the Raypak B6000 Boiler Control and Johnson Controls N2 compatible masters.
2.0 Metasys Slave Port Functionality 2.1 N2 Slave Communications The Comminications Interface card supports the Johnson Controls Metasys™ N2 Protocol, as a slave, on port 1. This capability allows the module to communicate data from the Raypak B6000 Boiler Control to a Johnson Controls Metasys Master such as the Johnson Controls Companion™ or Metasys software. The following discusses the functional capabilities of the card. 2.1.
Writing Attributes The data object attributes can be configured by a master using the following commands: 2/1 2/2 2/3 2/4 Write Analog Input Attributes Write Binary Input Attributes Write Analog Output Attributes Write Binary Output Attributes Controlling the B6000 Controller Access to the control functions is made available through the Override commands.
Hardware Setup 3.0 3.1 1500 Interface Card Setup 3.1.1 Connecting Power to the T-2 Card The T-2 Card requires an external source of DC voltage. The DC source voltage should be between 9V and 30V. The power is connected to TB1, located near the two 9 pin serial port connections. The connection to TB1 is as follows: TB1-1 9-30 VDC (+) TB1-2 Common(-) 3.1.2 SW 1 1 2 3 4 5 6 7 8 O F F ↓ • • Dip Switch Configuration The T-2 card is configured primarily through two sets of dip switches.
The parameters are defined as follows: Baud Rate: The baud rate at which the module is to operate. The baud rate is configured as follows: Value Baud Rate 0 1 2 3 4 5 6 300 Baud 600 Baud 1200 Baud 2400 Baud 4800 Baud 9600 Baud* 19200 Baud If a value outside of this range is selected,upon firing the power up process the card’s LEDs will flash on 1/2 second intervals until a correct address is selected. Powering down is not necessary.
4.0 N2 System Protocol Support The Raypak T-2 card supports several data read and write commands for the N2 System protocol. The decision on which command to use is made depending on the type of data being addressed, and the level of protocol support in the master equipment. The following sections detail the different commands supported by the module. 4.1 Attribute Commands The T-2 Interface card supports the reading and writing to the data object attributes.
5.0 Diagnostics Several hardware diagnostics capabilities have been implemented using the LED indicator lights on the front of the 1500 card. The possible conditions as indicated by the lights are: 5.1 LED Indicators Several hardware diagnostics capabilities have been implemented using the LED indicator lights on the front of the module.
