• • •
Converts between V.24/RS-232 DTE and X.21 DCE Operates at data rates up to 200 kbps Has a built-in buffer to accommodate phase differences between the receive and transmit clocks of the DCE No external power required Easy to install Miniature, lightweight
DESCRIPTION • MIC-24T/21C Miniature Interface Converter, converts between DTEs with the V.24/RS-232 interface and DCEs with the X.21 interface at data rates up to 200 kbps (see Figure 1 for the data flow diagram).
• MIC-24T/21C performs both physical and electrical conversion between the two interfaces. The circuitry is designed to provide short range interface, i.e. for connection of co-located devices
• MIC-24T/21C has a built-in buffer to accommodate phase differences between the receive and transmit clocks of the DCE.
• No AC power is required. The device uses ultra-low power derived from the DTE and DCE data and control signals.
