PDSM-743 Serial-to-Ethernet Device Server, 3x RS-232 and 1x RS-485, Metal Case

The PDS-743 CR is a programmable device server that brings RS-232 and RS-485 serial devices onto an Ethernet network. Its built-in COM ports can be mapped to standard Virtual COM ports on a Windows PC using the VxComm utility, so existing serial software can keep working without modification.The unit also acts as a Modbus TCP to RTU/ASCII gateway, allowing SCADA and HMI systems that speak Modbus TCP to reach Modbus RTU or ASCII slave devices. The built-in MiniOS7 runtime and programmable Xserver structure let engineers build custom Ethernet applications on the device.Four digital inputs with latched and counter functions and four open-collector digital outputs add local I/O to the serial gateway. The plastic enclosure mounts on DIN-rail or wall, and a removable terminal block simplifies wiring. The CA-0910 cable is included.ApplicationsFactory automationBuilding automationHome automation

The PDS-743D (ordering code PDS-743D CR) connects serial equipment to an Ethernet network. It provides three RS-232 ports and one RS-485 port, so existing serial instruments, meters and controllers can be reached from IP-based systems without redesigning their wiring or software.The VxComm driver and utility can map the device's serial ports to virtual COM ports on a Windows PC, so legacy serial applications can keep their standard COM port interface. The unit also runs a programmable Xserver structure on the built-in MiniOS7 platform 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. The unit includes a watchdog timer, ESD protection on the serial port and a removable terminal block, and is supplied with a CA-0910 cable.ApplicationsFactory AutomationBuilding AutomationHome Automation

The PDSM-743D connects serial devices to an Ethernet network. Its built-in COM ports can be presented as standard COM ports on a Windows PC through the VxComm utility, so existing serial software can keep working over the network without changes to the application.The device runs the MiniOS7 operating system and can be programmed with the Xserver structure to build custom Ethernet applications. It can also act as a Modbus TCP to RTU/ASCII gateway, which suits SCADA and HMI systems that use Modbus TCP. Digital inputs support latched and counter functions, and the RS-485 port uses a self-tuner ASIC controller.The unit has a metal case, a watchdog timer for harsh environments, and a +/-4 kV ESD protection circuit on the serial ports. Wiring is made through a removable terminal block, and the unit is wall mounted. The package includes a CA-0910 cable.ApplicationsFactory AutomationBuilding AutomationHome Automation

The PPDS-743-MTCP connects RS-232 and RS-485 serial devices to an Ethernet network, with three RS-232 ports and one RS-485 port on a single unit. The VxComm driver can map the device's COM ports to standard COM ports on a Windows PC, which is useful when existing COM-based software needs to reach remote serial equipment.The unit is programmable through the Xserver structure and runs the built-in MiniOS7 runtime. It also works as a Modbus TCP to RTU/ASCII gateway for SCADA and HMI systems. Four digital inputs support latched and counter functions, and four open-collector NPN digital outputs are rated at 30 VDC and 100 mA max.Power can be supplied by IEEE 802.3af Class 1 PoE over standard Category 5 cable, or from a +12 ~ 48 VDC terminal block. The plastic casing mounts on DIN-rail or wall, with an operating range of -25 ~ +75 °C. The ordering code includes a CA-0910 cable.ApplicationsFactory AutomationBuilding AutomationHome Automation

The PPDSM-743-MTCP connects serial equipment to an Ethernet network. It offers three RS-232 ports and one RS-485 port, so existing serial devices can be brought onto an IP network without replacing them. The VxComm driver can map the built-in COM ports to standard COM ports on a Windows PC, which helps with legacy software that expects local serial connections.The unit is also a Modbus TCP to RTU/ASCII gateway, allowing SCADA and HMI systems that speak Modbus TCP to communicate with Modbus RTU or ASCII slave devices on the serial side. Four digital inputs and four open-collector digital outputs add basic discrete I/O to the same unit. It can be powered from an IEEE 802.3af, Class 1 PoE switch over a standard Ethernet cable, or from a +12 ~ 48 VDC terminal block supply.The metal housing is intended for wall mounting in industrial environments, with an operating temperature range of -25 ~ +75 °C. The ordering code includes a CA-0910 cable.ApplicationsFactory AutomationBuilding AutomationHome Automation

The PPDS-743D-MTCP is a programmable device server that brings legacy serial equipment onto an Ethernet network. It provides two 3-wire RS-232 ports, one 5-wire RS-232 port and one RS-485 port, so existing serial devices can be connected to Ethernet without replacing them. The VxComm driver and utility can map the built-in COM ports to standard COM ports on a Windows PC.Beyond serial bridging, the unit runs the built-in MiniOS7 and the Xserver programming structure, so custom Ethernet applications can be developed on the device. It also acts as a Modbus TCP to RTU/ASCII gateway for SCADA and HMI systems that speak Modbus TCP. Four digital inputs with latched and counter functions and four open-collector digital outputs handle local signals alongside the serial traffic.Power can be supplied over Ethernet via IEEE 802.3af (Class 1) PoE, or from a +12 ~ 48 VDC terminal block. The unit is supplied with the CA-0910 cable, mounts on a DIN-rail or wall, and is rated for an operating range of -25 ~ +75 °C.ApplicationsFactory AutomationBuilding AutomationHome Automation

The PPDSM-743D-MTCP links up to four serial devices, three RS-232 and one RS-485, to an Ethernet network, so existing serial equipment can be integrated without replacing it. Its built-in gateway converts Modbus TCP requests to Modbus RTU or ASCII, which suits SCADA and HMI systems that speak Modbus TCP to serial field devices.The unit is fully programmable, with a built-in MiniOS7 operating system that starts in about one second. It provides four digital inputs with latched and counter functions and four open-collector digital outputs, plus a 5-digit 7-segment LED display for status information.
