MEGACOLD L– Issue 01
Command 90 Select AUDIT protocol/ telemetry enablement:
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
The transmission happens according to the following specifications:
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 offers the choice of the drive speed that must be consistent with the
setting on card no. 082925 (see relevant instructions). The settable range is between 2400 baud and 19200
baud, or negotiable between machine and terminal (option only valid for connection with cable). 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.
Then set the option "enable telemetry". Value 1 = function enabled; Value 0 = function not enabled. Default
value = 0.
Command 91 Enter machine identification data:
The first figure requested in numeric format with a maximum of 8 digits refers to the serial number (Eva-Dts
ID101 field); the second, in alpha numeric format with a maximum of 32 characters refers to the location of
the machine (Eva-Dts ID104 field); the third figure requested is the machine identification code number (asset
number) with a maximum of 12 characters (Eva-Dts ID106 field). For the method of entering the description
in alpha-numeric format, consult the table of command 95.
Command 92 Clear sales data:
The command is used to clear the machine's sales data (see command 10). A special access code must be
entered for this operation. The procedure is as follows:
•
Programming mode, ............................................................................ Command 0 appears on the display
•
Type 92 and press ENTER, ................................................................... Code 0000 appears on the display
•
Type 1221 and press ENTER, .......................................................'CLEAR DATA?' appears on the display
Press the ENTER key to clear all the sales data whereas press ESC to return to the main menus without
saving the changes.
Command 93 Displays the temperature status over the last 24 hours:
Option available for the slave machines if enabled (see Command 49).
This command displays the trend of the internal temperature during the last 24 hours. The values are
recorded every 60 minutes. To view all the values simply press the 'B' button.
The values can only be recorded if the clock is programmed (see Command 02). After programming the
clock, all the data is automatically zeroed.
Tx - Pin 7
-9600 baud - 8 bit of data
