The RAD MIC Series is a family of interface converters enabling connection between the DTE and DCE with different interfaces (see Table 1). MIC models operate in synchronous applications at data rates up to 2048 kbps with balanced interface at both ends, or at data rates up to 200 kbps with V.24/RS-232 at one end.
MICs perform both the physical conversion and the electrical conversion between the two interfaces. The circuitry is designed to provide short range interface conversion, i.e., for connection of devices which are
co-located.
Most RAD MIC models operate without AC power, using ultra-low power from the DTE and DCE data and control signals.
The various devices of the RAD MIC series are described in the following paragraphs.
MIC - 24/35
For converting between V.24/RS-232 and V.35 interfaces. MIC - 24/35 is switch-selectable and is used either for connecting a V.24/RS-232 DTE to a V.35 DCE, or for connecting a V.24 DCE to a V.35 DTE.
MIC - 24/36
For converting between V.24/RS-232 and V.36/RS-422 interfaces. MIC - 24/36 is switch-selectable and is used either for connecting a V.24/RS-232 DTE to a V.36/RS-422 DCE, or for connecting a V.24 DCE to a V.36 DTE.
MIC - 232/530
For converting between V.24/RS-232 and RS-530 interfaces. MIC - 232/530 is switch-selectable and is used either for connecting a V.24/RS-232 DTE to an RS-530 DCE, or for connecting a V.24/RS-232 DCE to an RS-530 DTE.
MIC - 24T/21C and MIC - 21T/24C
For converting between V.24/RS-232 and X.21 interfaces. MIC - 24T/21C is used for connecting a V.24/RS-232 DTE to an X.21 DCE. MIC - 21T/24C is used for connecting a V.24 DCE to an X.21 DTE, and has a built-in buffer to accommodate phase differences between the receive and transmit clocks of the DCE.
MIC - 24/11 (data only)
For converting between V.24/RS-232 and V.11/RS-422 interfaces. MIC - 24/11 is switch-selectable and is used for connecting a V.24/RS-232 DTE to a V.11/RS-422 DCE, or a V.24 DCE to a V.11 DTE. This model converts only data signals, and not control signals, and is suitable only for asynchronous applications.
MIC - 35T/21C and MIC - 21T/35C
For converting between V.35 and X.21 interfaces. MIC - 35T/21C is used for connecting a V.35 DTE to an X.21 DCE. MIC - 21T/35C is used for connecting a V.35 DCE to an X.21 DTE, and has a built-in buffer to accommodate phase differences between the receive and transmit clocks of the DCE. MIC - 21T/35C requires an external power supply.
CBL-36T/21C
For converting between RS-449/422 (V.36/V.11) and X.21 interfaces. The CBL-36T/21C cable is used for connecting a V.36 (RS-449/422) DTE to an X.21 DCE. This model is only a cable for performing cross-wiring between the two interfaces.
CBL-530T/21C and MIC - 21T/530C
For converting between RS-530 and X.21 interfaces. The CBL-530T/21C cable is used for connecting an RS-530/422 DTE to an X.21 DCE. This model is only a cable for performing the cross-wiring between the two interfaces. MIC - 21T/530C is used for connecting an RS-530 DCE to an X.21 DTE, and has a built-in buffer to accommodate phase differences between the receive and transmit clocks of the DCE. MIC - 21T/530C requires an external power supply.
CBL-530/449
For converting RS-530 to RS-449/422 (V.36/V.11) interfaces. CBL-530/449 is used for connecting an RS-530 DTE or DCE to an RS-449/422 (V.36) DCE or DTE. This model is only a cable for performing cross-wiring between the two interfaces.
MIC - 530T/35C and MIC - 35T/530C
For converting between RS-530 and V.35 interfaces. MIC - 530T/35C is used for connecting an RS-530 DTE to a V.35 DCE. MIC - 35T/530C is used for connecting an RS-530 DCE to a V.35 DTE.
MIC - 35T/36C and MIC - 36T/35C
For converting between V.35 and V.36/V.11 (RS-449/422) interfaces. MIC - 35T/36C is used for connecting a V.35 DTE to a V.36 (RS-449/422) DCE. MIC - 36T/35C is used for connecting a V.35 DCE to a V.36 DTE.
