RS-232
Communications
Modems and Cables
PC Package/Answer modem
Kit number: C01533
Parameter settings
Set SYS_PAR, page 8, Remote CFN Port Type:
3 = direct connect or dumb modem, full duplex.
Setup procedure:
1. Connect a terminal to the modem with a 1:1
cable male DB-25 to male DB-25 (C04549) or
male DB-25 to female DB-9 (C04654).
2. Connect the modem’s power cord and turn
modem power switch ON.
3. Use the steps below:
Hayes/Hayes-Compatible 14.4 and above
Type: AT&F&D2S0=1&C1B1&Q6X0&K0&W
↵
Modem responds: OK
Type: ATQ1&W ↵
Modem does not respond
Note: If a Panasonic data terminal (or other data
terminal requiring DCD) is being used to configure
the modem, set the parameter in the terminal to
Ignore the DCD level of the RS-232 signal. This is
necessary because the AT&C1&W command causes
the modem to drop DCD which may be required by
the terminal being used to configure the modem
unless the terminal is set up to ignore the DCD level.
