PDSM-721 Metal Serial-to-Ethernet Device Server, RS-232/RS-485, 6 DI/7 DO

PDS-721 is a programmable device server that brings RS-232 and RS-485 serial equipment onto an Ethernet network. A virtual COM driver lets a Windows PC treat the device's serial ports as local COM ports, so existing serial software can keep working over the network.The unit runs the built-in MiniOS7 and can be programmed for custom Ethernet applications. It also acts as a Modbus TCP to RTU/ASCII gateway, which suits SCADA and HMI systems that speak Modbus TCP but must reach serial field devices. The six digital inputs support latched input and counter functions, and the seven open-collector outputs are rated for up to 30 VDC and 100 mA.This plastic-cased CR version is a DIN-rail or wall-mounted unit with a removable terminal block for wiring. It is supplied with the CA-0910 cable. For a metal enclosure, see the PDSM-721 listed in the same series.ApplicationsFactory automationBuilding automationHome automation

The PDS-721D brings a serial RS-232 device and an RS-485 device onto an Ethernet network without changing the serial application. Its virtual COM driver lets a PC address the device's serial ports as standard COM ports, which suits legacy software that expects a local serial connection.Beyond serial bridging, the unit runs a programmable Xserver structure on a built-in MiniOS7 platform, so custom Ethernet logic can be developed on the device. It also acts as a Modbus TCP to RTU/ASCII gateway, allowing Modbus TCP SCADA or HMI systems to reach Modbus serial slaves. The six digital inputs support latched and counter functions, and the seven open-collector outputs and LED display add local status and control.The PDS-721D is supplied with a CA-0910 cable and suits factory, building and home automation installations. It is housed in a plastic casing with DIN-rail or wall mounting, a removable terminal block, and a watchdog timer for use in harsh environments.ApplicationsFactory AutomationBuilding AutomationHome Automation

PDSM-721D is a programmable serial-to-Ethernet device server that brings one RS-232 and one RS-485 serial device onto an Ethernet network. The VxComm utility can map the built-in serial ports to standard virtual COM ports on a Windows PC, so existing COM-based software can reach the devices over the network.The unit runs the built-in MiniOS7 operating system, which boots in one second, and supports a programmable Xserver structure for custom Ethernet applications. It also works as a Modbus TCP to RTU/ASCII gateway for SCADA and HMI systems. Six digital inputs support latched D/I and counter functions, while seven open-collector sink outputs handle switching duties. A watchdog timer and ±4 kV ESD protection on the serial port are included for demanding environments.The metal case, removable terminal block and wall mounting suit industrial installations powered from 10 to 30 VDC and operating between -25 and +75 °C. The package includes a CA-0910 cable.ApplicationsFactory automationBuilding automationHome automation

The PPDS-721-MTCP links an RS-232 and an RS-485 serial device to an Ethernet network. Its VxComm utility can map the serial ports to virtual COM ports on a Windows PC, so existing COM-based software can reach serial equipment across the network without changes to the application.Beyond simple serial bridging, the unit runs a programmable Xserver application on its built-in MiniOS7 real-time operating system and can act as a Modbus TCP to RTU/ASCII gateway for SCADA and HMI systems. It also provides latched digital inputs and counter functions for local event handling on site.Power can be supplied over Ethernet using IEEE 802.3af Class 1 PoE, or from a +12 ~ 48 VDC terminal block. The CA-0910 cable is included with this ordering code, and the unit mounts on a DIN-rail or a wall.ApplicationsFactory automationBuilding automationHome automation

The PPDSM-721-MTCP brings a serial RS-232 device and an RS-485 device onto an Ethernet network through a single compact unit. Its virtual COM support, provided by the VxComm utility, lets existing PC software address the device server's serial ports as standard COM ports, so legacy serial applications can be kept in service while the network is upgraded.The unit also works as a Modbus TCP to RTU/ASCII gateway for SCADA and HMI systems that speak Modbus TCP. Six digital inputs with latched and counter functions and seven open-collector digital outputs add local I/O, and the device can be powered either from a PoE switch using IEEE 802.3af Class 1 or from a +12 ~ 48 VDC terminal block.The metal case, watchdog timer and ESD protection on the serial port are intended for demanding environments. The package includes a CA-0910 cable, and the unit is rated for an operating range of -25 ~ +75 °C and wall mounting.ApplicationsFactory automationBuilding automationHome automation

The PPDS-721D-MTCP links serial equipment to an Ethernet network. Its built-in RS-232 and RS-485 ports can be presented to a PC as virtual COM ports using the VxComm utility, so existing serial software can keep working over the network. It also acts as a Modbus TCP to RTU/ASCII gateway, which suits SCADA and HMI systems that speak Modbus TCP to talk to RTU or ASCII devices.Beyond gateway duties, the unit is a programmable device server with on-board I/O. It provides 6 wet-contact digital inputs with latched and counter functions, and 7 open-collector sink (NPN) digital outputs. A 5-digit 7-segment LED display and a Power/PoE indicator give local status, and a watchdog timer is included for unattended operation.Power can come from an IEEE 802.3af Class 1 PoE switch over a standard Category 5 cable, or from a +12 ~ 48 VDC supply on the removable terminal block. The plastic casing mounts on a DIN rail or a wall, and the unit is rated for -25 ~ +75 °C operation. A CA-0910 cable is included with this ordering code.ApplicationsFactory AutomationBuilding AutomationHome Automation

PPDSM-721D-MTCP links an RS-232 device and an RS-485 device to an Ethernet network, so existing serial equipment can be integrated without replacing it. Its built-in Modbus TCP to RTU/ASCII gateway lets SCADA and HMI systems that speak Modbus TCP reach serial devices. The unit is powered either over Ethernet using IEEE 802.3af, Class 1 PoE or from a +12 ~ 48 VDC terminal block.The unit combines 6 wet-contact digital inputs and 7 open-collector sink (NPN) digital outputs with a programmable device server. It supports latched digital input and counter functions. The VxComm utility maps the serial ports to virtual COM ports on 32/64-bit Windows 7 SP1, 10, 2012 and 2016.
