DS1101 as a 3.5-channel
RS232 port Serial Device Server

The DS1101 is a compact Tibbo BASIC/Tibbo C-programmable RS232 controller with Ethernet and optional Wi-Fi* connectivity.

The DS1101 features a multi-channel RS232 port. The device has a single DB9M connector and is priced as a single-port RS232 server, yet packs 3.5 independent serial channels

The DS1101 comes preloaded with a fully functional serial-over-IP (SoI) application that turns the DS1101 into a powerful multi-channel serial-over-IP converter, a.k.a. the device server.

Both network interfaces — Ethernet and Wi-Fi — are fully supported by the SoI application, with automatic switchover depending on the network conditions.

As a device server, the DS1101 is compatible with Tibbo Device Server Toolkit (TDST) for Windows. TDST includes the Virtual Serial Port Driver (VSPD), which enables you to use all serial channels of the DS1101 as remote COM ports of your PC. The Linux version of the VSPD is available as well.

Another feature of the DS1101 is its software-controlled power output on pin 9 of the DB9 (serial port) connector — you can power an attached serial device directly through the DS1101. Alternatively, the DS1101 itself can be powered through the pin 9. The device can also be powered via its power jack or the available power-over-Ethernet module.*

In addition, the DS1101 can be equipped with a 96x32 monochrome OLED display. This display shows the current configuration and communication state for each channel, Wi-Fi status, and other useful information.

There are eight LEDs on the device's front: green and red main status LEDs, yellow Ethernet link LED, and five blue LEDs, which are used for Wi-Fi signal strength indication. A buzzer is provided as well.

Each DS1101 is supplied with the DIN rail and wall mounting plates.
