H-S81-HS Installation & Operation Manual — P/N LS10114-000HI-E:A 2/24/2015 39Central Unit Rack Parts of the H-S81-HS System J4 & J5: Printer/Debug / Host ComputerTwo connectors for 10-pole flat cable, allowing the connection of a 40 or 80 column serial printerand of a PC for configuration data transfer. Use the S81-CFT10/2 cable for connecting to the PC. J6: DisplayA connector for 20-pole flat cable, allowing the connection to the S81-U1006 display module.2.2.2 S81-U1002-1DescriptionThis module is system central unit. Besides the micro-controller, the moduleincludes the following elements: Flash memory, buffered static Ram, watchdogcircuit and Ethernet controller. The CPU module can be used in both single andredundant configuration. In this last case, two CPUs operating in parallel areused. Both CPUs process the information received from the modules, but onlyone of the two CPUs runs the commands. In case of failure of the primary CPU,the other one keeps on carrying out all the tasks without any interruption of themachine cycle.Technical FeaturesJ4 Connector Direction DB9 FemalePin Signal Signal Pin1 DTR DCD 13 TXD RXD 25 RXD TXD 37 DCD DTR 49 GND GND 52 DTR DSR 64 CTS RTS 76 RTS CTS 88 RI 910 NU Figure 2.9 RS232 Connections• Safety rating: applicable up to SIL3• Micro-controller: Renesas H8-2318 at 25Mhz• RAM memory: 4 MB, lithium battery buffered• FLASH memory: 2 MB• Ethernet Output: 10/100BaseT with RJ45 connector• Watch Dog: external• Redundancy YES• Supply voltage: 22-29VDC• Quiescent current: 70mA• Operating temperature: -5 - 50 °C• Storage temperature: -30 - 80 °C• Maximum humidity: 95% (RH) non-condensing• Hot swap capability: yes
