UPGRADING GEM FIRMWARE (OPTIONAL) 

F

IRMWARE

 

The “firmware” is the software program that runs inside the GEM’s processor. The concept of upgrading 
firmware is like that of upgrading software on a PC. Typically when a company releases a new version of 
software, improvements have been made and new features added. The same applies to firmware. 
 
The GEM has two processors and therefore two firmware types: “COM” and “ENG”. The “COM” 
firmware is the principal operating system of the GEM and commonly upgraded. 

COM Firmware 

This firmware handles most of the GEM functions such as packet communication, all settings and system 
functions. Most upgrades will involve this firmware. 

ENG Firmware 

The engine (ENG) firmware does all of the energy processing for channels 1 to 32. This firmware rarely 
requires upgrading. 
 

It is strongly recommended to upgrade the GEM’s firmware if the “COM” firmware version is older 
(less) than ver 2.20. The ENG firmware should also be upgraded.

The “baud rate” is the speed at which data is transferred between the GEM and the communication 
module.  
 
The GEM requires a baud rate of 19,200 for “COM” and “ENG” firmware upgrades. Older GEMs used this 
baud rate exclusively however newer firmware versions allow the GEM to be switched between 19,200 
baud and 115,200 baud. 

The 19,200 baud rate is mandatory for firmware upgrades.

 Under normal 

operating conditions, it is advised to set the GEM for the faster 115,200 rate to greatly improve its 
performance. 
 
If clicking the “Get GEM Info” results in a response similar to that of Figure 22, then the baud rate is not 
detected and no baud rate change is required since this older version used 19,200 baud only. If the 
response resembles that of Figure 21, then the baud rate is selectable and in this case MUST be changed 
from 115,200 to 19,200 before proceeding with the firmware upgrade. 

Changing to 19200 Baud 

Figure 29 below shows the result of the “Get GEM Info” function of newer firmware. In this example the 
GEM is set for 115,200 baud and needs to be changed before proceeding with firmware upgrade. 
 
Click the “19200” button in the “Change Com1 Baud” section (Figure 29). The entire procedure will take 
approximately 32 seconds.
