PDSM-742 Programmable Serial-to-Ethernet Device Server, 3x RS-232, 1x RS-485

The PDS-742 is a programmable device server that brings serial equipment onto an Ethernet network. It provides three RS-232 ports and one RS-485 port, so existing serial instruments, controllers and field devices can be integrated without replacing them. The VxComm driver and utility can map the device's serial ports to virtual COM ports on a Windows PC, allowing standard COM-based software to communicate with them over the network.Beyond simple serial-to-Ethernet bridging, the unit runs the built-in MiniOS7 from ICP DAS and can be programmed for custom Ethernet applications. It also operates as a Modbus TCP to RTU/ASCII gateway, supporting SCADA and HMI systems that communicate over Modbus TCP. A watchdog timer and +/-4 kV ESD protection on the serial ports help it cope with demanding industrial environments.The PDS-742 ordering code includes the CA-0910 cable. It has a plastic casing, a removable terminal block for wiring, and can be mounted on a DIN rail or on a wall. It is rated for an operating temperature of -25 ~ +75 °C and is supplied from a +10 ~ 30 VDC terminal block supply.ApplicationsFactory automationBuilding automationHome automation

The PPDS-742-MTCP brings legacy serial equipment onto an Ethernet network. It provides three RS-232 ports and one RS-485 port, and can be powered over Ethernet using IEEE 802.3af Class 1 PoE from a standard category 5 cable. Its VxComm driver can map the device's serial ports to virtual COM ports on a Windows PC, so existing COM-based software can keep working.Beyond simple serial tunnelling, the unit runs a programmable device server environment with the built-in MiniOS7 firmware, and it can act as a Modbus TCP to RTU/ASCII gateway for SCADA and HMI systems that speak Modbus TCP. Serial ports carry +/-4 kV ESD protection, and the RS-485 port uses a self-tuner ASIC controller.This ordering code is supplied with a CA-0910 cable. The unit has a plastic casing, a removable terminal block for wiring, and can be installed on a DIN rail or wall. Its operating range is -25 ~ +75 °C.ApplicationsFactory automationBuilding automationHome automation

The PPDSM-742-MTCP brings three RS-232 serial ports and one RS-485 port onto an Ethernet network, so existing serial devices can be integrated without rewiring them to a PC. The VxComm driver and utility map the built-in COM ports to standard COM ports on Windows, which suits legacy serial software that expects local ports. Supplied with a CA-0910 cable.Beyond simple device serving, the unit can be programmed through its Xserver structure and runs the built-in MiniOS7. 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 RS-485 port includes a self-tuner ASIC controller.Power can be supplied over the Ethernet cable using IEEE 802.3af, Class 1 PoE, or from a +12 ~ 48 VDC terminal block. The metal casing and removable on-board terminal block are intended for industrial wiring, and the unit is wall mounted with an operating temperature range of -25 ~ +75 °C.ApplicationsFactory AutomationBuilding AutomationHome Automation

PPDS-742D-MTCP links three RS-232 devices and one RS-485 device to an Ethernet network, so existing serial equipment can be reached from PCs, SCADA and HMI systems without replacing it. The built-in virtual COM support lets software written for local COM ports keep working over the network, and the unit also acts as a Modbus TCP to RTU/ASCII gateway for Modbus TCP clients.The unit is built around a programmable Xserver structure and the MiniOS7 runtime, so custom Ethernet logic can be added to the serial interfaces. Each serial port has ESD protection rated at +/-4 kV, and the RS-485 port uses a self-tuner ASIC controller. A watchdog timer supports operation in harsh environments.Power can be supplied over Ethernet via IEEE 802.3af, Class 1 PoE, or from a +12 ~ 48 VDC terminal block. The removable terminal block and DIN-rail or wall mounting suit panel installation, and a single-LED power/PoE indicator plus a five-digit 7-segment display show status on the unit. This ordering code includes the CA-0910 cable.ApplicationsFactory automationBuilding automationHome automation

The PPDSM-742D-MTCP links serial devices to an Ethernet network. It provides three RS-232 ports and one RS-485 port, and its built-in Modbus TCP to RTU/ASCII gateway lets SCADA and HMI systems that speak Modbus TCP reach serial slave devices.
