Connection of the

ZULU Modem to an RS232 or USB host terminal device such as a PC serial

port may easily be achieved using the Application Schematic below.

The 9 way ‘D’ socket (J1) provides the standard pin out required to connect directly to the serial

port of any std PC using a 9 way male/female cable. The MAX3232 (a low voltage RS232 line

driver) provides level conversion between the RS232 levels on the serial port and the logic levels

pins of the

ZULU Modem module.

Alternatively the same can be achieved using the ZULU Eval Boards
