IC952A, IC953A
For converting between V.24/RS-232 and
V.11/RS-422 interfaces. These converters are
switch-selectable and are 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. These Converters convert only
the data signals, not the control signals, and are
suitable only for asynchronous applications.
To install the Converter:
1) Separate the two halves of the plastic cover by
pressing the marked places on the sides,
starting at the cable end.
2) Connect the V.11 two twisted pairs to the screw
terminal block; transmit pair to “XMT” and
receive pair to “RCV.” A ground is provided for
optional connection of the cable shield.
3) Set the DTE/DCE switch of the Converter to
the required position (factory set to DCE).
