Using An External Demodulator; How To Install The Software Modules - Wavecom W 4010 User Manual

The number of data and stop bits can be adjusted with [F2] to either 7 data bits / 1 stop bit, 7 data bits /
2 stop bits, 8 data bits / 1 stop bit, 8 data bits / 2 stop bits.
The parity can be adjusted with help of [F3] to NO, ODD, or EVEN.
The programmed values are stored in a non-volatile memory and stay stored even without power. By means
of [F1], [F2], and [F3] the operator can easily configure the WAVECOM decoder to communicate with any
RS-232C equipment.

In order to transfer the data's of the serial interface, it is necessary to load a terminal Program in a PC. With
the terminal Program you can save the data's on a disk.
In order to connect an external demodulator you must first open the case. Locate jumper #3 and change it
from the left-hand position (internal demodulator) to the right-hand position (seen from the front panel).
The external demodulator can now be connected to the 5-pole DIN rear panel jack. The external demodula-
tor input can be driven with either TTL or RS-232 level signals.
Before undertaking any changes in the equipment make sure the power is disconnected.
The EPROM memory chips have an easily seen indentation on one end. When inserting the EPROM, this in-
dentation must point to the front of the equipment. Also the EPROM markings should be oriented similar to
that of EPROM A. The EPROM has to be inserted in the proper sense, otherwise it probably will be de-
stroyed!
Set the DIP switch, located behind module C, as follows:
