Introduction
The PDS series is a family of Programmable Device Servers, also known as "Serial-to-Ethernet
gateway", that are designed for linking RS-232/422/485 devices to an Ethernet network. The user-
friendly VxComm Driver/Utility allows users to easily turn the built-in COM ports of the PDS series
into standard COM ports on a PC. By virtue of its protocol independence, a small-core OS and high
flexibility, the PDS series is able to meet the demands of every network-enabled application.
The PDS series includes a powerful and reliable Xserver programming structure that allows you to
design your robust Ethernet applications in one day. The built-in, high-performance MiniOS7 boots
the PDS up in just one second and gives you fastest responses.
The PPDS(M)-700, PPDS(M)-700-MTCP and PPDS-700-IP67 series features true IEEE 802.3af-
compliant (classification, Class 1) Power over Ethernet (PoE) using a standard category 5 Ethernet
cable to receive power from a PoE switch like the NS-205PSE.
The PPDS(M)-700-MTCP and PDS-5105D-MTCP also works as a Modbus/TCP to Modbus/RTU
gateway that supports most SCADA/HMI communications based on the Modbus/TCP protocol. The
PDSM-700 is the PDS-700 with Metal Case (RoHS) and the PPDSM-700-MTCP is the PPDS-700-MTCP
with Metal Case (RoHS). Metal Case version includes stronger protection than PDS-700 and PPDS-
700-MTCP.
The PPDS-700-IP67 is a special design for the toughest applications. It can be directly mounted to
any machine or convenient flat surface. The rugged packaging and IP67 connectors are rated to
protect against water, oil, dust, vibration, and much more.
