Cas-Lite RS232 is a Bi-Directional Serial to Ethernet Conversion Bridges. It converts a full duplex RS-232 serial stream to a TCP/IP stream. The serial stream consists of at least the transmit data, plus optional "modem control " signal. The Cas-Lite connects to and network enables most RS232 serial devices.

The CAS-Lite RS-485 supports higher speeds (up to 250 kbps), longer distances, and may be used in a multidrop configuration. The CAS-Lite RS485 can be used in a multidrop network spanning up to 1200 m (4000 ft), and there can be as many as 32 attached devices.
The CAS-Lite RS485 is the master device and provides software support for typical RS485 protocols, where data packets are less than an upper limit of 1020 bytes.

The Power Distribution Module (PDM) conveniently distributes a single DC input into five individual outputs for centrally powering a cluster of CAS-Lite Units (RS232 / RS485). Each output is protected with an auto-resetting PTC to protect connected units by isolating each attached CAS-Lite. LED power indicators provide visual feed back and power status for each CAS-Lite connected to the PDM.
