DS1102 as a 3-channel
RS232/422/485 Device Server

The DS1102 is a compact Tibbo BASIC/Tibbo C-programmable RS232/422/485 controller with Ethernet and optional Wi-Fi* connectivity.

The DS1102 features a multi-channel RS232/422/485 port. The device has a single DB9M connector and is priced as a single-port product, yet provides 3 independent RS232 channels, 2 independent RS422 channels, or a single RS485 to ethernet channel.

The DS1102 comes preloaded with a fully functional serial-over-IP (SoI) application that turns the DS1102 into a powerful multi-channel, multi-protocol 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 DS1102 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 DS1102 as remote COM ports of your PC. The Linux version of the VSPD is available as well.

The device can be powered via its power jack or the available power-over-Ethernet module*.

In addition, the DS1102 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 DS1102 is supplied with the DIN rail and wall mounting plates.
