Sending and receiving SDS- and Status Messages using the Hash
(#) Command Sequence
SDS- and Status messages can be sent over the TGW-100s serial ports using the #-
command (Hash Command)
The idea behind the #-commands is to have a simple method of sending and receiving
SDS and Status messages for machine to machine, for human to machine or for human
to Voice-Terminal applications.
The Hash-Command is defined as a header control sequence within two #-characters,
followed by a SDS or status information in the following way:
# SSI # Text, Data or Status
Control
character
ISSI /
GSSI
Text or Status
Remark
T
Yes
Text

S

Numeric Status:
0-65535
Sends a Status Message
D

Text or Data

header information
C
Yes/No MMI Command
Sends a MMI command to a different
TGW-100 or to the own device
Rules:
The transmitting TGW serial interface (COM or AUX) has to be in Hash Command
Mode
The first character inside the # signs is the control character T, S or D
Followed by an ISSI or GSSI
The characters outside the # signs are: Text Information, Data or Status Information
On manual (human) input:
Choose the CR LF on "COM Port Serial Parameter Settings" and use a terminal
software (e.g. HyperTerminal on your computer)
On PLC or PC communication:
Choose Timeout or 3964R (CR LF will work also)
