10/100BaseT Ethernet port 3.5-channel RS232 port (DB9M) Power input/output through DB9 DIN rail and wall mounting plates included Optional OLED display Optional WiFi interface or Power-over-Ethernet Compact — 90 × 48 × 25 mm
The DS1101 is a compact programmable controller targeting cost-sensitive serial-over-IP and serial control applications. The device comes preloaded with a fully functional serial-over-IP application.
A key feature of the DS1101 is its multi-channel serial port. The device has a single DB9M connector and is priced as a single-port device, yet packs four independent serial channels. Have no use for those DSR and DTR lines? Turn them into RX and TX of an additional serial channel. Don't want CTS and RTS either? That's one more channel! In total, there are 15 different configurations or "port mappings" to choose from, starting from a standard single-channel configuration (RX, TX, CTS, RTS, DSR, and DTR) all the way to a 3.5-channel setup (RX, TX, RX2, TX2, RX3, TX3, and RX4).
Another feature of the DS1101 is software-controlled power output on pin 9 of the RS232 port, so you can power an attached serial device directly through the DS1101. Alternatively, the DS1101 itself can be powered through this pin when not powered via its barrel jack or optional PoE module.
There are eight LEDs on the device's front: green and red main status LEDs, a yellow Ethernet link LED, and five blue LEDs which can be used to show WiFi signal strength when using the optional WiFi module.
The DS1101 is equipped with a buzzer that you can use for audible status indication.
The picture above shows the DS1101 with an optional 96×32-pixel monochrome OLED display. See the Add-On option selector at the bottom of this page to order the DS1101 with the display and/or the WiFi or Power-over-Ethernet module.
Each DS1101 is supplied with plates for mounting on a DIN rail or a wall. The lower picture shows what the plates look like installed on the unit.

Tibbo Integrated Development Environment (TIDE) It takes just one key (F5) to compile your Tibbo BASIC and/or Tibbo C project, upload it to the target, and run it with full debugging capabilities. You don't need any special debugging hardware; just connect your DS1101 to the LAN and debug right through the network.
