How to Buy

The ConnectPort TS 4x4 family of device servers provides serial device network connectivity and remote Ethernet switch capability. Supporting multiple serial and Ethernet ports, this product is ideal for medical, utility, traffic, retail and POS, industrial automation, banking and many more applications.

Digi’s patented RealPort® software establishes a connection between the server and networked serial devices, creating a local COM/TTY port on the server. RealPort technology allows almost any software application to work with Digi networked device servers without modification.

The Python® development environment built into ConnectPort TS 4x4 device servers enables application customization. This easy-to-use, universal programming language allows complete control of device connections, data manipulation and event based actions.

  • All RJ-45 to DBx cables are 10-pin. Only the RJ-45 to RJ-45 cable is an 8-pin cable.
  • All RJ-45 adapters are 8-pin. When using these adapters with modems or other applications that require DCD on pin 1, you must turn on altpin.
  • If altpin is turned off, the hardware signal on pin 1 becomes DSR instead of DCD. This alternative can be used if DCD is not required, and DSR is needed instead.
