,
STANDBY
,
SAFE-CONN XX
,
RUNNING XX
,
COOL DOWN XX
,
PUMP
ERROR XX
, or
INTERLOCK XX, SHUT DOWN XX, CALIBRATION XX
, where XX is the pump error
code.
0E
SET PRESS UNITS. Specifies the default pressure units. Parameters: UUU where UUU is pressure
units — Torr, MBR, or PA.
0F
GET DATE/TIME. Reads the date and time. Response:
w dd/yy hh:mm
, where
w
is day of the week
(1=Sunday);
dd
is date;
mm
is month;
yy
is year;
hh
is hour, and
mm
is minute.
10
SET DATE/TIME. Sets the date and time. Response:

, where
w
is day of the week
(1=Sunday);
dd
is date;
mm
is month;

1
. Response:
ssss L/S
,
where
ssss
is pump size.
12
SET PUMP SIZE. Parameters: 1, size or 2*, size. Response:
ssss L/S
. Size = 0 or 10 – 1200.
1C
GET SUPPLY SIZE. Parameters: 1 or 2*. Response: “LARGE” or “MEDIUM”.
1D

Response: n.nn. n.nn is 0.00 – 9.99.
1E
SET CAL FACTOR. Sets calibration factor. Parameters: 1, n.nn or 2*, n.nn. n.nn is 0.00 – 9.99.
20
GET HV STRAPPING. Reads the supplies' high voltage strapping.
Parameters: 1 or 2
1
. Response:
5600
or
7000
.
22
GET PARM FACTOR. Reads the line voltage that the unit is strapped for. Response:
120
or
240
.
23
TELL PARM FACTOR. Informs the computer which line voltage the unit is strapped for. NOTE: This
does NOT change the input voltage strapping! Parameter:
120
or
240
.
24
GET LINE FREQUENCY. Reads the line frequency. Response:
50HZ
or
60HZ
.
25
SET DISPLAY. Changes the display parameter. Parameters: 1, parameter or 2*, parameter. Parameter
is VOLTS, CURRENT, or PRESSURE. Note: only the first character of each parameter is actually
required.
27
TSP TIMED. Sets TSP mode of operation to TIMED. Cycles TSP once every X minutes, for Y seconds,
Z number of cycles, but only if pressure is above specified amount. Parameters: XXX (000 – 999), YYY
(000 – 999), ZZZ (000 – 999), and X.XE-XX is specified pressure units (Torr, MBar, or PA).
28
TSP OFF. Disables the TSP. Sets values: ZZZ = 0, X.XE-XX = 0.1E-9.
29
FILAMENT ACTIVE. Sets which filament is active during TSP Timed.
Parameters: N (filament number).
2A
TSP STATUS. Reports how many cycles left and minutes each filament has been used. Response:
CCC, N- MMMM, N- MMMM, N- MMMM, and N- MMMM.
CCC (number of cycles left to execute), N (filament number), and MMMM (total amount of logged time in
minutes that the filament has been used).
2B
FILAMENT CLEAR. Executed after degassing. Resets logged time of all filaments to zero.
2C
FILAMENT AUTO. Automatically advances to the next filament if the one being used is open.
Parameters: YES or NO.
2D
TSP CONTINUOUS. Sets the TSP mode of operation to continuous.
2E
SUBLIMATION LEVEL. For TSP Timed mode of operation, sets the TSP controlling parameter (watts or
amps) and its value. Parameters: XXX,P, N. XXX = value; P = W for watts or A for amps; N = number
of seconds of on time (0 - 255).
