EGM-5 Operation Manual V. 1.04  102  support@ppsystems.com 
 
corresponds to a parameter value (See Get on page 106). When G,x is sent from 
the Host, the value associated with that particular parameter is returned. 
 
Example: 
Sent from Host: G,1<CR>  (Get Zero Type) 
Received from EGM-5:  
+<CR> 
G,1,1.000<CR>  
 
In this example the value of Zero Type is 1 (Automatic). 
with 
Parameters 
“H” Command    (Get Run Hours) 
 
This command gets the total hours of unit operation. The x parameter is the 
number that determines the module the hours is retrieved from. 
 
Module number:  
1 = Main Controller 
4 = IRGA Module 
Example: 
Sent from Host: H,1<CR> 
Received from EGM-5: 
+<CR> 
H,1, 463.1 
 
In this example, the main controller has reported 463.1 hours of operation. 
with 
Parameters 
“M” Command    (Measure String) 
 
This command performs a “one shot” measurement output. Each time ‘Mx’ is sent 
to the instrument, one set of data is displayed in the currently specified format 
(i.e., M1, M2, etc.). The value of x determines where the data will be sent: 
 
H=Host 
M=Memory Stick 
W=Wireless 
A=All three 
 
Example: 
Sent from Host: MH<CR> 
Received from EGM-5: 
+<CR> 
M3, 03/06/15, 09:32:15, 1, 0003, 1094, 1004.2, 327, 0.0, 00.0, 20.41, 00<CR> 
 
In this example, the data is sent to the Host only. The Host Measure Format 
setting had been set to 3. See Get/Set Parameter Values Table on page 106
 for 
“N” Command    (Read Voltages) 
 
This command returns five system voltage measurements in volts. External 
Voltage, System Voltage, Flow Sensor Voltage, AUX1 (Analog Output) Voltage 
and O
2
 Sensor Voltage are sent in order in comma-delimited format. 
 
Example: 
Sent from Host: N<CR>
