PDS-752 Programmable Serial-to-Ethernet Device Server, 4x RS-232/1x RS-485

The PDSM-752 brings four RS-232 serial ports and one RS-485 port onto an Ethernet network, so legacy serial devices can be connected to Ethernet. A VxComm driver maps the device server's COM ports to standard virtual COM ports on a Windows PC, allowing existing serial software to keep working over the network.Built around an 80 MHz 80186-class CPU with a built-in MiniOS7 operating system and the Xserver programming structure, the unit can be extended with custom Ethernet logic. It also acts as a Modbus TCP to RTU/ASCII gateway, passing requests from SCADA or HMI systems to Modbus serial slaves. A metal case, watchdog timer and ESD protection on the serial ports suit demanding installations.This ordering code includes the CA-0910 cable. Power is supplied from a removable terminal block rated at +10 ~ 30 VDC, and the unit is designed for wall mounting within an operating range of -25 ~ +75 °C.ApplicationsFactory automationBuilding automationHome automation

PDS-752D CR connects existing serial equipment to an Ethernet network without changing the devices themselves. It provides four RS-232 ports and one RS-485 port, so engineers can bring legacy controllers, meters and field devices onto an IP network. The VxComm driver can map the device server's serial ports to virtual COM ports on a Windows PC, which allows serial software to run unchanged.Beyond simple serial tunnelling, the unit is a programmable device server built around the Xserver programming structure and the built-in MiniOS7 operating system. It can also act as a Modbus TCP to RTU/ASCII gateway, passing requests from SCADA or HMI systems to serial Modbus devices. The RS-485 port uses a self-tuner ASIC controller, and the watchdog timer supports operation in demanding environments.The removable terminal block simplifies wiring in industrial installations. The unit is supplied with the CA-0910 cable and can be mounted on a DIN rail or on a wall. Where a metal housing or Power over Ethernet is required, the similar listed models should be checked against the requirements.ApplicationsFactory automationBuilding automationHome automation

The PDSM-752D links serial equipment to Ethernet. It provides four RS-232 ports and one RS-485 port, so existing serial instruments, controllers and field devices can be reached over a network without replacing them. The VxComm driver maps the serial ports to virtual COM ports on a Windows PC, which lets legacy serial software keep working unchanged.Because the unit is programmable, engineers can build their own Ethernet communication logic on the built-in MiniOS7 platform. It also acts as a Modbus TCP to RTU/ASCII gateway, allowing SCADA and HMI systems that speak Modbus TCP to poll Modbus RTU or ASCII slaves on the serial side.This variant has a metal housing and an LED display, and it is supplied with a CA-0910 cable. It is wall-mounted and powered from a 10 to 30 VDC terminal block. The rated operating range is -25 to +75 °C, which suits cabinets and plant floors in factory, building and home automation installations.ApplicationsFactory automationBuilding automationHome automation

The PPDS-752-MTCP CR bridges four RS-232 devices and one RS-485 device onto an Ethernet network. Its built-in COM ports can be presented as standard COM ports on a Windows PC through the VxComm driver, so existing serial software can keep working with networked hardware.Beyond simple serial tunnelling, the unit is programmable and runs the built-in MiniOS7 operating system. It also acts as a Modbus TCP to RTU/ASCII gateway, letting Modbus TCP SCADA and HMI systems poll serial Modbus slaves. Power can come from a PoE switch under IEEE 802.3af Class 1 or from a +12 ~ 48 VDC terminal block, and the removable terminal block simplifies field wiring.This ordering code ships with the CA-0910 cable. The device is suited to factory, building and home automation projects where serial equipment needs to be integrated into an Ethernet infrastructure.ApplicationsFactory AutomationBuilding AutomationHome Automation

The PPDSM-752-MTCP is a programmable device server from the PDS-700 series that brings RS-232 and RS-485 serial devices onto an Ethernet network. It is supplied in a metal case with Power over Ethernet, and it also works as a Modbus TCP to RTU/ASCII gateway for SCADA and HMI systems that communicate over Modbus TCP.Choose this ordering code when you need four RS-232 ports and one RS-485 port in a compact, wall-mounted unit. Power can come from an IEEE 802.3af Class 1 PoE switch over a standard Category 5 cable, or from a +12 ~ 48 VDC terminal block. The removable terminal block simplifies wiring in industrial installations, and the metal casing offers stronger protection than the plastic PDS-700 variants.The unit includes the CA-0910 cable. The VxComm utility maps the built-in COM ports to virtual COM ports on a PC, and it supports 32/64-bit Windows 7 SP1, 10, 2012 and 2016. A watchdog timer and +/-4 kV ESD protection on the serial ports add robustness for demanding environments.ApplicationsFactory AutomationBuilding AutomationHome Automation

PPDS-752D-MTCP connects legacy serial equipment to an Ethernet network. Four RS-232 ports and one RS-485 port give engineers a compact way to bring several serial devices online without rewriting their firmware. Virtual COM drivers let Windows applications address the device server's serial ports as if they were local COM ports.The unit runs a programmable device server environment on a built-in MiniOS7 kernel, so custom Ethernet logic can be developed on the device itself. It also operates as a Modbus TCP to RTU/ASCII gateway, allowing Modbus TCP SCADA or HMI clients to poll RTU or ASCII slaves on the serial side. Power can be supplied over a standard Ethernet cable from an IEEE 802.3af Class 1 PoE switch, or from a +12 ~ 48 VDC terminal block.For field installation, the unit offers a Watchdog Timer, ESD protection of +/-4 kV on the serial ports and a removable terminal block for wiring. It mounts on DIN-rail or wall and is supplied with a CA-0910 cable. The model is listed with CE, UKCA, FCC, RoHS and WEEE certification in the source data.ApplicationsFactory automationBuilding automationHome automation

The PPDSM-752D-MTCP CR connects up to five serial devices, four RS-232 and one RS-485, to an Ethernet network. Its built-in virtual COM driver lets software on a Windows PC address the remote serial ports as local COM ports, so existing serial applications can often be retained without rewriting them.Beyond simple serial bridging, the unit runs a programmable Xserver environment on the built-in MiniOS7 and can act as a Modbus TCP to RTU/ASCII gateway for SCADA and HMI systems. Power can be supplied over the Ethernet cable via IEEE 802.3af Class 1 PoE, or from a +12 ~ 48 VDC terminal block, and a watchdog timer and ESD protection on the serial ports support operation in demanding environments.The metal housing, wall-mounting design and removable terminal block suit installation in factory, building and home automation panels. A CA-0910 cable is included with this ordering code.ApplicationsFactory automationBuilding automationHome automation
