MEGACOLD S/M – Issue 01
Command 90 Selecting the AUDIT / telemetry enabling protocol:
The control card has a jack RS232.
The connector I/O is a 9 poles with male container in which the following pins are used:
- Pin 2 Tx
The transmission happens according to the following specifications:
-9600 baud
The transfer of the data is ruled by a control signal DTR (active high) given by the device to fetch data.
The data fetch from the machine happens as follows:
•
Connection of the device to fetch data to the jack RS232.
•
Press pushbutton data sending.
•
After the transmission of data the request to disconnect the device is displayed.
Through command 90 it is possible to choose the quantity of data sent to the jack RS232. There are three
levels:
•
level 1 totals regarding the transactions
•
level 2 totals regarding the transactions of level 1, plus sales per each selection
•
level 3 totals regarding the transactions of level 1, data regarding the last 5 power off and on of the
machine; data regarding the error events that have happened.
If the command is set at 4, the machine dialogue with the outside world is achieved by means of an 082928
infrared interface, based on the specifications of the EVA-DTS protocol.
If the command is set at 5 the machine dialogues with the external world through an infrared 082925
interface (IRDA interface), according to the specifications of the protocol EVA-DTS vers.5.0.
Then, if the preceding option has been set at 4 or 5, the machine proposes selecting the input / output
direction: towards the infrared interface (082928 or 082925 OPTICAL LINK) or towards RS232 (connector
situated on the card). In the latter case the connector pins used are 2= VMC Tx, 3=VMC Rx, 5= GROUND in
which case the transmission speed is fixed at 9600 baud. To select press any key on the keyboard to scroll
the various direction options and confirm the desired value by pressing "B"
If the initial option is set at 5 the machine requests that the peripheral address be inserted: key in the desired
value and press "B".
If the initial option is set at 5 the machine proposes selecting the transmission speed which must be
consistent with the setting of card no. 082925 (see relevant instructions). The setting range is between 2400
baud and 19200 baud. To select press any key on the keyboard to scroll the various speed options and
confirm the desired value by pressing "B".
If the command is set at 6 the machine dialogues with the user by means of DEX-UCS protocol.
Afterwards set the "telemetry enabling" option. Value 1 = function enabled; Value 0 = function disabled.
Default value = 0.
