FEATURES
APPLICATIONS
DESCRIPTION * MIC-24/CL enables communication
between equipment with current loop interface and devices with RS-232 / V.24 interface. MIC-24/CL operates bidirectionally, full or half-duplex, converting the RS-232 / V.24 voltage levels to loop closure or loop opening. active and passive current loop transmissions:
* * * * * * * * * *
Conversion of RS-232/V.24 to current loop, bidirectional Distances up to 6.5 km / 4 miles Data rates up to 19.2 bps Full or half duplex 20 mA current loop, 60 mA optional Active or passive units LEDs indicating RD, TD activity (active only) DCE/DTE switch Miniature, lightweight Easy to install
* MIC-24CL is available in two models, for
MIC -24/CL/A (active) allows both the transmitter and the receiver to supply the current loop source or only the transmitter to supply the source (strap-selectable, see Figures 1,2. The active unit operates with 20 mA (60 mA optional ordering) and requires a standard external power supply of 12V. LED indicators, POWER, TD and RD, monitor the data flow for transmit and receive signals. MIC -24/CL/P (passive) always accepts the supplied loop current from both transmit and receive lines (see Figure 3). The passive unit operates with 20 or 60 mA, without requiring an external power source. Its power is derived from the RS-232 / V.24 data and control source signals.
* Both models feature a DCE/DTE switch to
simplify installation and eliminate the need for cross cables.

INSTALLATION
Caution. This is a delicate instrument. Be careful when setting jumpers or performing any actions within the product so that you do not break or shake any components.
6.
Plug the unit directly into the 25-pin connector of the RS-232/V.24 equipment and fasten with the screws.
Note: For the MIC-24/CL/A unit, plug in the power connector and check that the POWER LED is on.
MIC-24/CL is easy to configure and install. Review Table 1 and Figure 4 for the factory settings as the unit may already be strapped to suit your application. If not, follow these steps: 1. Open the unit by pressing the marked places on the sides, starting at the cable end. Table 1. Strap Selection Strap
DCE/DTE
Function
Factory Setting 3.
Figure 4. Strapping Diagram In the MIC-24/CL/A (active unit), set the double RECEIVER strap to the position for the Receive circuitry to be active or passive. When RECEIVER is set to ACTIVE, "Rxa" is the positive lead and "Rxb" is the negative lead. When RECEIVER is set to PASSIVE, the polarity is reversed: "RXa" is the negative lead and "RXb" is the positive lead. Connect the 4-wire line to the screw terminal block: transmit pair to "TX" and receive pair to "RX", maintaining polarity. Note: Remote "TX" should be connected to local "RX" and vice versa. 5. Close the unit by pressing the two halves of the cover together.
Designates if unit is DCE configured as a DCE or DTE Selects the Receive ACTIVE circuitry to be either active (supplying current) or passive (sinking current).
ACTIVE/ PASSIVE (on the active unit only)
2.
Set the DCE/DTE switch to the required position. When set to DCE, the unit is configured as a DCE for connection to a computer or terminal. When set to DTE, it operates as a DTE.
