Note A loose label sticker that includes the unique device password is included in the box. Retain this label sticker with your hardware records.
This default password will be needed if the device is factory reset and you want to access the web UIon the device.
2 Confirm serial pinouts
Step 1: Configure DIP switches (MEI models only)
For PortServer TS 1-4 port models, if the connected device is not EIA-232, set the DIP switches as shown for the serial port according to your serial device requirements.

Switch settings
Up/On
Down/Off
For PortServer TSPMEI series only, in EIA-232 mode, if switch 3 is
down, 9V power is provided on pin 9 (DTR). If switch 3 is up, power on
pin 9 is disabled and 5V power can be enabled on pin 1 (RI) through
the software interface. If using EIA-422 or EIA-485, the DIPswitch
settings are the same as for any other PortServer TS 1-4 MEI model.
If switch 4 is up, the termination resistor is connected. If switch 4 is down, the termination resistor is not connected.
Step 2: Review serial pinouts

Note The CTS and RTS control signals are available as separate differential signals in the EIA-
422/EIA-485 4-wire mode. Do not use these differential signals in 2-wire mode. The CTS and
RTS differential signals are not terminated or biased internally. Any termination or biasing
must be done externally.
