Special order, delayed despatch

The E-P732-DIO83 is a dual Ethernet to Serial converter with 2 serial ports, 3 mains relay outputs and 8 digital inputs. There is one dedicated RS232 port whist the other port can be either RS232, Rs422 or RS485. Serial data can be sent directly through a TCP/IP connection using Virtual Serial Port software or directly.  The 3 mains rated relay outputs can be controlled by writing a control word to the TCP port. Digital input status is automatically reported on state change or can be obtained though a simple TCP port request.

Ethernet to Serial

The E-P732-DIO83 is a dual Serial to Ethernet converter that can network-enable your serial devices, such as weigh scales, PLCs, Data acquisition systems, point of sale, bar code scanners, access control systems, gas meters, printers - anything!

Connect it to your network via a standard RJ45 connector, set-up its' IP address and TCP port number and you are away. With the supplied Virtual Com port software you can simply communicate with your serial device as if it were connected to the back of your PC. Programmers can communicate directly with the E-P732-DIO83 using standard TCP/IP protocols.

Relay Outputs

The E-P732-DIO83 has 3 mains rated change-over relays. The Common, normally open (NO) and normally closed (NC) contacts are accessed via removable screw terminals.

The relays are activated by sending a control word to the digital IO TCP port, Digital I/O Port 1. The top 3 bits of the 8-bit word controls the corresponding relay;

Relay 1 - send 10000000 for on, 0000000 for off

Relay 2 - send 01000000 for on, 0000000 for off

Relay 3 - send 00100000 for on, 0000000 for off

Digital Input

There are 8 digital inputs which can respond to volt-free contact or a voltage input: the voltage need to be 3.3 to 30V to register a logic 1.

Data is automatically sent to the digital IO TCP port 2 on digital input state change, or data can be requested by sending any character to the port

An 8-bit word is returned, with each bit corresponding to a digital input - the MSB corresponding to DI8, the LCB to DI1, etc.

Box-to-Box Mode

A pair of E-P732-DIO83's can be set up in Client-Server mode where they will send RS232 data and digital IO data between each other without any PC intervention.


CVBrowser is a simple tool to detect and configure the installed EDIO device. CVBrowser allows you to set the IP address and TCP/IP port to suit your Network. Users can then use any web-browser to configure the advanced settings of EDIO device hardware such as Baud rate, socket port, serial I/O and etc.

VirtualSerialPort Console

VirtualSerialPort Console is a COM port redirection software application for Windows PC platforms. Its function is to re-direct customer application data destined for a local serial (COM) port on a PC. Rather than going out the local port, the data is transmitted across the Ethernet network using TCP/IP. The eDIO attached to the network receives the data and presents it on its serial port. Conversely, data into the serial port of the eDIO-100 is sent back to the customer application via the network to the VirtualSerialPort Console software. The VirtualSerialPort Console software then presents the data to the customer application as if it were from a local serial COM port.

One of the main objectives of the VirtualSerialPort Console software is to eliminate the need for a customer to modify their application. If the application knows how to connect to a local serial port, it can by default talk to a remote serial port on a device server using the VirtualSerialPort Console software. No understanding of how to develop networking software is required.
