MODEL 232i9

The Model 232i9 Signal Isolator is a compact, plug-in unit providing a data path with full electrical isolation

between any two devices connected for bi-directional serial data communication.

The Model 232i9 Isolator Module is equipped with two 9 way, D type connectors, one male plug and one female

socket. The Isolator can therefore be directly interposed in any suitably configured RS-232 communications

circuit. The pin-out configuration is in accordance with the EIA/TIA 574 standard.

Both ports are line powered. The socket side from DTR/RTS (pins 4 and 7) and the plug side from the DSR/CTS

(pins 6 and 8) control lines of the connected devices, so eliminating the need for external power supplies.

Internal jumpers allow selection of RTS, CTS, DTR, DSR and DCD control signals for hardware handshaking.

The user must select the appropriate handshaking mode for his application. Due to the adapter's size, it was not

possible to implement isolation for all of the handshaking lines. It may be necessary for the user to determine

what the system at either end of the link requires from the handshaking lines. The figures below show how the

adapter can be configured to accommodate a variety of handshaking modes. Please note the end to which the

handshaking applies, e.g. Figure 4 loops DTR to DSR at the host end (9 way socket), and the equivalent lines are

not looped at the remote end. Figure 1 below shows the default jumper settings for RTS-CTS handshaking, and

Figures 2 to 5 show the other possible hardware handshaking configurations.
