Honeywell Excell 500/600 Controll System 500-XCL5010 ユーザーズマニュアル

modem connected to the Excel controller serial port, and it 
then transmits via GSM like a cellular (mobile) phone. 
NOTE:  Communication via GSM requires firmware version 

V2.3.0 or higher. 

The maximum communication speed is determined by the 
current GSM standard, which is 9600 baud. Due to a special 
transmission mechanism, the effective communication 
throughput is lower than 9600 baud – however this will be 
noticeable only when high data volumes are transmitted, e.g. 
when application download is performed. 

Use of the M20 Terminal on-board aircraft is 
forbidden. Use of a Cellular Engine in an aircraft, such 
as for the purpose of wireless connection of an aircraft 
based HVAC system to an XBS central, can endanger 
navigation, it interferes with the cellular network and it 
is illegal. Failure to comply with this prohibition may 
lead to temporary suspension or permanent 
cancellation of Cellular Engine services for the person 
who disregards this prohibition and/or to legal action 
against said person.

Users are advised to NOT use the M20T in 
automotive service stations. 

Users are reminded of the necessity of complying with 
restrictions regarding the use of radio devices in fuel 
depots, chemical plants and locations where 
explosives are ignited. 

Additional precautions are as follows: 

•   When receiving calls on a public highway, such as 

a cooling control system of a refrigeration truck 
being called by an XBS central, the M20T is not 
permitted to use "warning" devices which causes 
the vehicle’s horn to sound or the lights to flash. 

•   Drivers are advised not to use the handheld 

microphone or the telephone handset while their 
vehicle is in motion, except in emergencies. Use 
the hands-free facility to speak only if it does not 
divert your attention from the traffic. 

•   Operation of the M20T can disrupt the operability 

of inadequately protected medical devices. Please 

address all questions to a doctor or the 
manufacturer of the medical device. 

•   The M20 Terminal shall not be used within wet 

environment, such as in public baths. 

•   If your M20 Terminal, your SIM card or both go 

missing, notify your network operator immediately 
in order to avoid misuse. 

The Siemens M20 Terminal (shown below) is required for 
GSM communication. In addition, a 3V Mini SIM card with 
personal identification number (PIN) is required for the M20T. 
The Mini SIM card, supplied by the GSM Network Provider, 
must be released for data communication at 9600 baud.
