Description
When an alarm or failure occurs, the Product will print the current reading, date,
time, and either ALARM or FAIL to the RS-232 port. The instrument will print
once every 30 seconds as long as the alarm or fail condition is present.
Setup
You will need the following: the Product, a 1220 40-column printer, and a cable
(LMI PN: 8303-674)
The printer should be configured at 2400 bps (baud), no parity, 8 data bits, 1 stop
bit, and no handshaking. See printer manual for proper setup instructions.
Date and Time
Check the month and day (MMDD) by pressing the LOW ALARM and
HIGH ALARM
buttons simultaneously. The month and day will be displayed as
long as those buttons are pressed. The month and day can be set from 0101 to
1231.
Check the year (YYYY) by pressing the LOW ALARM and CAL CONST buttons
simultaneously. The year will be displayed as long as those buttons are pressed.
The year can be adjusted from 0000 to 9999.
Check the hours and minutes (HHMM) by pressing the LOW ALARM and
DEAD TIME
buttons simultaneously. The hours and minutes will be displayed as
long as those buttons are pressed. The hours and minutes can be adjusted from
0000 to 2359.
RS232 Data Format
The data will be sent to the RS-232 port as:
Byte 1 0 x Byte 18 Space (20H)
Byte 2 x x Byte 19 H
Byte 3 x OR x Byte 20 H
Byte 4 x x Byte 21 :
Byte 5 . . Byte 22 M
Byte 6 x 0 Byte 23 M
Byte 7 Space (20H) Byte 24 :
Byte 8 Space (20H) Byte 25 S
Byte 9 Space (20H) Byte 26 S
Byte 10 M Byte 27 Space (20H)
Byte 11 M Byte 28 A Space
Byte 12 / Byte 29 L F
Byte 13 D Byte 30 A OR A
Byte 14 D Byte 31 R I
Byte 15 / Byte 32 M L
Byte 16 Y Byte 33 Carriage Return (0DH)
Byte 17 Y Byte 34 Line Feed (0AH)
Example output:
0642.1 04/21/95 16:56:24 ALARM
0000.0 04/21/95 08:32:16 FAIL
