78. CRIPTION RS 232 DESCRIPTION Almost all laptop and desktop computers have at least one RS 232 serial communications port available It was initially developed for the emerging computer industry in the 1960 s Origi nally it was a method of sending data from a mini or main frame computer to devices such as printers punch card readers teletypes magnetic tape units and modems In those early days the maximum speed at which RS 232 was capable of transmitting about 9600 bits per second was quite satisfactory as most of the receiving devices were mechanical in nature except for modems and barely able to keep up with these speeds RS 232 uses single ended TX transmit data and RX receive data This means a common ground wire is shared between TX and RX so only 3 wires are needed for a data only serial channel TX RX and GND Disadvantages of single ended signaling is that it is more susceptible to noise than differential signaling RS 422 485 effective cable distances are shorter typically about 50 Ft total due to low noise immunity and data rates are slower Additionally there is the limitation that only two devices can communicate together master and slave RS 422 RS 485 DESCRIPTION When serial communications started moving into the industrial environment it was quickly noted that because of the high electrical noise potential from electric motors valves solenoids fluorescent lighting etc that the n

ICATIONS SETUP LL d Frick BY JOHNSON CONTROLS Q5 CONTROLLER MAIN BOARD HISTORY AND IDENTIFICATION The processor board shown on this page is known as the O5 board and it is based on the Pentium micro processor platform The operating software that this board runs is known as Quantum LX software This software displays graphic information and data on the LCD screen in a format that is similar to the way a Windows6 desktop computer screen displays a Web browser the Internet The O5 board can be identified by the presence of a large aluminum heat sink located on the board Ad jacent to the processor board is an Interface board which allows the user to attach local communications connections via the four orange connectors RS 422 and RS 485 ports There are also a number of jumpers present on both the O5 and the Interface board These jumpers MAY need to be modified by gualified personnel to config ure the Quantum 5 for specific applications The O5 utilizes Flash Card technology There is a Flash Card socket located on the under side of this main board The O5 board has the LX Operating System pre loaded at the factory so this Flash Card feature will primarily be utilized for future program updates The information that follows will primarily describe the jumper configuration for communications set tings as well as wiring diagrams for the different types of communications that are possible with the O5 Q5 C
