4 Communicating with the Recorder

c. Set the Baud Rate. This will be the rate at which the recorder will
communicate with the external modem. It does not control the rate
at which the modems communicate with each other. Unlike a direct
serial link, there is no need for this baud rate to match that of the re-
mote computer. A rate faster than the modem’s top speed is recom-
mended to take full advantage of the modem’s compression
capabilities.
d. Select External Modem.
e. The Modem Initialization String lets you set any special command
codes required by your modem. The factory default for this field is
“M1” for external modems. These default values are all that are re-
quired for most modems.
f. Save your changes, close the Utilities tab and disconnect.
