Serial connectors
The two serial connectors support RS-232
(default), RS-422, and RS-485 standards. To use
RS-422/485 standards, change the settings with
the IoT IOBOX DT1 IO CONTROLLER application.
To download the application, go to:
https://support.lenovo.com.
They are also compatible with IEEE 802.3af or
IEEE 802.3at devices. In this case, the dc power
input to the box must be higher than 135 W.
Data transfer speed is 10/100/1000 Mbps (The
box is equipped with RTL8153B).
They support full duplex flow control (IEEE
802.3x).
Do not support Wake On LAN.
DC-in power connector
The 3-pin Phoenix dc-in power connector
accepts dc power input from 9 V (-5%) to 36 V
(+5%).
Baud rate: 50 bps ~ 115.2 Kbps
For Baud rate, Data bits, Parity, Stop bits, and
flow control detail setting, do the following:
1. Right-click the Start button to open the
Start context menu.
2. Click Device Manager, and then click
Ports(COM&LPT).
3. Double-click IoT IOBOX DT1 (COM3) or IoT
IOBOX DT1 (COM4), and then click Port
settings.
Ethernet connectors
The two Ethernet connectors are fully compliant
with IEEE 802.3, IEEE 802.3u, and IEEE 802.3ab.
The DC-in power LED indicator shows the status
of the dc power input.

:
The output voltage can range from 5 V to 30 V
when an external relay module, which has
been connected to external power source
separately, is connected to the Digital Output
connector.
