6.3.34 TIO
Test I/O. Test the relays. This command allows to switch
a single relay or several relays at a time.
S: TIO[,a,bb][]

R: a,bb
NOTE:
The relay status is a hexadecimal number. It may be
combined by the logical operator OR. Example: 24 =
Switching functions relays 3 and 6 on.
6.3.35 TKB
Test keyboard. Test the keyboard.

R: aaaa
The control character starts the test. The Vac-
uum Gauge Controller polls the keyboard and sends a
message to the computer.
NOTE:
The keyboard status is a binary number. It may be
combined by the logical operator OR. Example: 0011
= DOWN and UP pressed at the same time.

CAUTION
Relay test.
In this test the relays switch irrespective of the
actual pressure. This may cause unintended
switching of devices.
Unplug the RELAY connection before per-
forming a relay test.
Parameter Significance
a Test status
0 = Off
1 = On
bb Relay status
00 = All relays off
01 = Switching function 1 relay on
02 = Switching function 2 relay on
04 = Switching function 3 relay on
08 = Switching function 4 relay on
10 = Switching function 5 relay on
20 = Switching function 6 relay on
40 = Error signal relay on
7F = All relays on
Parameter Significance
aaaa Keyboard status
0000 = No button pressed
1000 = CH pressed
0100 = PARA pressed
0010 = DOWN pressed
0001 = UP pressed
