PDSM-743D Serial-to-Ethernet Device Server, 3x RS-232 + 1x RS-485, 4 DI/4 DO

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 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.
