  • Serial port server
  • Serial port server holder
  • Logger data cable(s), delivered with the spare part Wiring Set for the specific cabinet model (PDT101, analog channel, safety barrier, or galvanic isolator model)
  • Ethernet switch (for installation locations with only 1 Ethernet cable available)
  • Short RJ45 cable for connecting 2 Ethernet switches
  • Small flat head screwdriver

For item codes, see Spare parts and accessories.

For setup instructions of the DIGI serial port server, see DIGI PortServer® TS Family Quick Start Guide.

When adding more measurement devices in CAB100B, you may need to add more data loggers in the installation. A second serial port server is needed when the number of data loggers exceeds 4.

For installation sites with only 1 Ethernet cable available for the 2 serial port servers, an Ethernet switch is available as an option.

To order the second serial port server, a serial port server holder, an Ethernet switch, and the cabling for them, contact Vaisala.

  1. De-energize the cabinet: switch off mains power and the circuit breaker located inside the cabinet.

  2. Dismantle the serial port server holder assembly (ASM213139SP).

    To do this, unscrew the DIN rail locking mechanism attached to the side of the assembly.

  3. Mount the serial port server in the serial port server holder.

    Attach the holder to the serial port server using the 2 screws and washers provided in the packaging of the serial port server holder (ASM213139SP).

  4. Reattach the DIN rail locking mechanism to the serial port server holder, as shown below. Use the original washer and screw.

  5. Insert the power wires in the screw terminals of the serial port server and the Ethernet switch (if using) and tighten the screws.

    For the locations of the screw terminals, see 6.

  6. Mount the serial port server with its holder, and the Ethernet switch (if using), on the DIN rail.

  7. For installations including an Ethernet switch:

    Connect the serial port servers to the Ethernet switch using 2 RJ45 cables.

  8. Route the power wires through the cable duct to the power block, located below the serial port server and the Ethernet switch.

    See also callouts #3 in the figure in 9.

  9. Using the logger data cables provided in the spare part Wiring Set, connect the new data logger(s) and the serial port server.

    Route the data logger data cable along the vertical cable duct from the left side of the cabinet.
