Printer Parallel Interface; Serial Rs-232 Interface; Configuring The Baud Rate And Data Format - Wavecom W 4010 User Manual

In case of unreadable video text switch the W 4010 Off, switch On, push [F1] and then [F3]. The pro-
grammed values are stored in a non-volatile memory and keep stored even without power.
Before interconnecting the printer with the W 4010, make sure both units are turned off. The 36-pole Cen-
tronics printer output jack is located on the decoder's rear panel and is connected via the standardized Cen-
tronics cable to the similar jack on the printer. The printer can be used immediately thereafter. Although the
Centronics printer signals have been internally filtered against RFI emissions, it is recommended to use
shielded cables only.
Some services use high Baud rates with the result that not all printers can keep pace. Before buying a print-
er, make sure it can print as fast as the service which you wish to receive, otherwise characters will be lost
when the buffer is full.
The RS-232 serial connector is the 5 pole DIN type
and the diagrams below show the electrical connec-
tions and give a typical connection example.
Shielded cable is recommended, although it is not
absolutely necessary.
The baud rate and data format of the equipment
connected to the serial port and the WAVECOM de-
coder has to be identical. The serial port parameters
for the decoder default to 300 baud, 8 data bits,
and 1 stop bit. The decoder offers the possibility of
inverting the data shift, should this eventually be
necessary. To invert the polarity, open the case and
change the position of the jumper, right front, to-
wards the front panel.

GND 2 ––––––––––––––––––––––––––––––––––––––––––––––––– 7
DATA 3 ––––––––––––––––––––––––––––––––––––––––––––––––– 3
DTR 5 ––––––––––––––––––––––––––––––––––––––––––––––––– 20
The DTR line signals the decoder whenever the printer cannot accept any more characters. If this handshak-
ing is not necessary in a particular case, this connection does not have to be made. Xon/Xoff handshaking is
not supported.
The information from the TTL parallel output is identical with that from the serial port except that this output
has a level of 0 to +5 Volts.
1.7 CONFIGURING THE BAUD RATE AND DATA FORMAT FOR SERIAL COMMUNICATION
Choose module A by pushing the module key while watching the monitor. Thereafter push [F2] to obtain the
menu to setup the communication parameters. The [F1] key allows configuring the Baud rate to either
300, 600, 1200, 2400, 4800, or 9600 Baud.
