The DCP35 series of products is designed to allow RS-232 devices to be inter-connected over distances sufficient to cover any industrial or institutional complex of buildings. These line drivers feature a DIN rail mountable enclosure for application to a junction box, a panel, a relay rack, the sides of computer equipment, or anywhere a DIN rail can be mounted.
The DCP35 series does not require a power supply for operation. The use of low power circuits and a sensitive optically isolated receiver allows the devices to derive all necessary power from the RS-232 data and control signals. They are designed for full-duplex, asynchronous operation over two, DC-continuous, non-loaded, twisted-wire pairs. Two-wire simplex operation may be accomplished over one twisted- wire pair. The line driver circuits and, consequently, the host device are protected from electrical transients due to lightning strikes or operation of heavy industrial equipment.
Each device features a convenient DCE (Data Communication Equipment) to DTE (Data Terminal Equipment) switch which reverses pins 2 and 3 of the RS-232 connector. For installation and system troubleshooting each unit has diagnostic Light Emitting Diodes (LEDs) on the transmit and receive lines.
The DCP35 is available in a single or dual channel package. The RS-232 connector may be ordered as a male or female 9-pin connector. Field connection is made through pluggable solderless screw terminals.
Frequently Asked Questions
I’m having trouble getting the DCP35 to communicate with a datalogger.
I’m having trouble getting the DCP35 to communicate with a datalogger. To connect to the DCP35, open or download the DCP35 data sheet from the Media Attachments box to the right of this Content box or the DCP35 User Manual from the Media Attachments box to the right of this Content box.
The important aspect of the DCP35 is providing it with sufficient power for it to send data over usable distances at a reasonable data rate.
That said, pay special attention to the power specifications in the data sheet and to the “Power Requirements” and “Cable Capacitance Effects On Distances” sections of the user manual.
