<strong>Technical</strong> <strong>documentation</strong> v 1.07, <strong>RTCU</strong>-<strong>D4</strong><strong>Logic</strong> <strong>IO</strong>www.logicio.comDigital outputsThe digital outputs interface to the outside world via solid-state drivers. The digital outputshave their own separate power supply terminal, and must be supplied with a voltagebetween 5 and 34 VDC to operate correctly.Terminal Number DescriptionDOSUPP 35 Digital output supplyDOSUPP 36 Digital output supplyDOSUPP 37 Digital output supplyDO1 38 Digital output number 1DO2 39 Digital output number 2DO3 40 Digital output number 3DO4 41 Digital output number 4DO5 42 Digital output number 5DO6 43 Digital output number 6DO7 44 Digital output number 7DO8 45 Digital output number 8DO9 46 Digital output number 9DO10 47 Digital output number 10DO11 48 Digital output number 11DO12 49 Digital output number 12Programming port (RS232) / RS485 portThe programming port (RS232) is shared with the RS485 port, if the RS485 port is used,the RS232 port cannot be used, and vice versa.The connection to the programming port (RS232) is done using the RJ11 connector in thelower left corner on the <strong>RTCU</strong> Unit (see graphical view)This connector can be used as a general-purpose serial port and as a programmingconnector. In order to use the connector as a programming connector, the RSDET pin (pin6) must be connected to GND. When using this connector as a general-purpose serialport, the RSDET pin must be left unconnected, or it can be tied to the VCC pin(recommended).Page 6 of 10<strong>Logic</strong> <strong>IO</strong> ApS.
