 ATMI TGM Serial Driver Description  
The ATMI-TGM driver allows the FieldServer to transfer data to and from devices over RS-232 
using the ATMI-TGM printer port protocol.  
 
This driver connects to an ATMI TGM device using a serial connection. One device may be 
connected per FieldServer port. (This limitation exists because the protocol is node-less; that is, 
messages do not contain information about the node and thus messages from different TGM 
devices could not be distinguished if they were connected on the same port.) 
 
The driver reports Gas and sensor readings and Gas alarm / warning status.  The driver reports 
TGM module malfunctions. 
 
The driver is a client only driver.  
 
When reporting port and sensor data, the driver reports the gas name by setting a gas name 
index value.  The index value is obtained from a list of gas names / index values hard coded into 
the driver.  The list may be extended and/or modified using the configuration by using 
appropriate entries in the configuration CSV file.  The driver reports a second gas name index 
value based on reading the TGM calibration report.  When the report is read each gas is 
allocated an identifier value based on the gas’s position in the configuration report.   
 
The driver does not provide emulation of a TGM device and thus may not be used as a server. 
 
It is not possible to use this driver to write to the TGM device.
