PPDSM-734-MTCP Serial-to-Ethernet Device Server with PoE and Modbus TCP Gateway

The PDS-734 CR links legacy RS-232, RS-485 and RS-422/485 devices to an Ethernet network. Its built-in COM ports can be mapped to standard virtual COM ports on a Windows PC, so existing serial software can keep working over the network without rewriting the application.Beyond simple serial bridging, the unit runs a programmable device server environment and can act as a Modbus TCP to RTU/ASCII gateway for SCADA and HMI systems. Four digital inputs with latched and counter functions and four open-collector sink outputs add local discrete I/O, while a watchdog timer supports operation in demanding environments.The PDS-734 CR uses a plastic casing with a removable terminal block for wiring, and mounts on DIN-rail or wall. It is supplied with the CA-0910 cable.ApplicationsFactory automationBuilding automationHome automation

The PDSM-734 CR is a metal-case programmable device server that connects RS-232, RS-485 and RS-422/485 serial equipment to an Ethernet network. The VxComm driver presents the built-in COM ports as standard virtual COM ports on a Windows PC.An embedded MiniOS7 and the Xserver programming structure let engineers build custom Ethernet applications. The unit can also operate as a Modbus TCP to RTU/ASCII gateway for SCADA and HMI systems, while four digital inputs support latched and counter functions alongside four open-collector outputs.The PDSM-734 CR ordering code includes the CA-0910 cable. Wiring is made through a removable terminal block, the unit operates from -25 ~ +75 °C and carries CE, UKCA, FCC, RoHS and WEEE marks.ApplicationsFactory automationBuilding automationHome automation

The PDS-734D CR brings three serial ports, four digital inputs and four digital outputs onto an Ethernet network in a compact DIN-rail or wall-mounted unit. It suits engineers who need to connect legacy RS-232 or RS-485 field devices to a PC, SCADA or HMI system without rewriting the device firmware.The built-in MiniOS7 runtime and Xserver programming structure allow custom Ethernet logic to be added to the device. The unit can also act as a Modbus TCP to RTU/ASCII gateway, so Modbus TCP masters can reach serial slaves directly. Each digital input supports latched and counter functions, and the 4 DO channels are open-collector NPN sink outputs rated at 30 VDC and 100 mA.The CA-0910 cable is included with the ordering code. The removable terminal block and plastic casing with a built-in watchdog timer make installation and maintenance straightforward in industrial cabinets.ApplicationsFactory automationBuilding automationHome automation

The PDSM-734D is a programmable serial-to-Ethernet device server for bringing RS-232, RS-485 and RS-422/485 equipment onto an Ethernet network. Its metal case offers stronger protection than the standard PDS-700 housing, which suits cabinet and field installations where robustness matters.Each unit provides one RS-232, one RS-485 and one RS-422/485 port, plus four digital inputs and four open-collector digital outputs. The VxComm driver and utility map the built-in COM ports to standard COM ports on Windows PCs, so existing serial software can run over the network. The unit can also act as a Modbus TCP to RTU/ASCII gateway for SCADA and HMI systems.The PDSM-734D is supplied with a CA-0910 cable and is mounted on a wall. It operates from a +10 ~ 30 VDC terminal block supply across -25 ~ +75 °C.ApplicationsFactory automationBuilding automationHome automation

The PPDS-734-MTCP CR links RS-232, RS-485 and RS-422/485 serial equipment to an Ethernet network. Its programmable firmware runs on the built-in MiniOS7, which boots in about one second, so engineers can build custom Ethernet applications on the device. The Modbus TCP to RTU/ASCII gateway function lets Modbus TCP SCADA and HMI systems communicate with attached serial devices.Power can be supplied over Ethernet using IEEE 802.3af Class 1 PoE on a standard Category 5 cable, or from a +12 to 48 VDC source on the removable terminal block. The four digital inputs support latched and counter functions, and the four open-collector NPN outputs are rated at 30 VDC and 100 mA max.A VxComm driver allows Windows 7 SP1, 10, 2012 and 2016 applications, in 32-bit or 64-bit editions, to use the device's serial ports as virtual COM ports. The plastic housing mounts on DIN-rail or wall and is rated for -25 ~ +75 °C operation. A CA-0910 cable is included with this ordering code.ApplicationsFactory AutomationBuilding AutomationHome Automation

The PPDS-734D-MTCP CR is a programmable device server that brings legacy serial equipment onto an Ethernet network. It provides one RS-232, one RS-485 and one RS-422/485 port, so engineers can connect several serial devices to a single unit and reach them over TCP/IP without redesigning the field hardware.Beyond simple serial tunnelling, the unit runs a built-in programmable Xserver environment on the MiniOS7 operating system, which can be used to build custom Ethernet applications. It also acts as a Modbus TCP to RTU/ASCII gateway, allowing SCADA and HMI systems that speak Modbus TCP to communicate with serial Modbus devices. The VxComm driver and utility can map the built-in COM ports to standard COM ports on a PC running supported 32 or 64-bit Windows versions.Four digital inputs and four digital outputs are included for local switching and monitoring. The unit is powered either from IEEE 802.3af Class 1 Power over Ethernet or from a +12 ~ 48 VDC terminal block supply. Its plastic casing mounts on DIN-rail or wall, and the package includes a CA-0910 cable.ApplicationsFactory AutomationBuilding AutomationHome Automation

The PPDSM-734D-MTCP brings three serial devices onto an Ethernet network: one RS-232, one RS-485 and one RS-422/485 port. Its built-in VxComm driver can map the serial ports to standard COM ports on a Windows PC, so existing serial software can keep working over the network without modification.Beyond simple serial bridging, the unit runs a programmable Xserver environment on the MiniOS7 operating system and can act as a Modbus TCP to RTU/ASCII gateway for SCADA and HMI systems. Four digital inputs with latched and counter functions and four open-collector digital outputs add local I/O, while the LED display shows status at a glance.Power can come from PoE (IEEE 802.3af, Class 1) over standard Category 5 cable or from a +12 ~ 48 VDC terminal block.
