OPERATING FAULT ON T HE RS232C SERIAL LINK
In the event the
RS232C
connection does not operate as described in this manual, please
check the following points:
Absence of a reaction of the device when sending commands
The connection cord between the device of the
SEFELEC
series and the computer
must be connected correctly at the two ends and be of uncrossed type. The Sefelec
CO179 cord is not compatible with the device.
The devices in the SEFELEC series have several possible types of interfaces, check
in the configuration menu that the
RS232
mode was selected on the
INTERFACE
line.
The end of message character must be the LF character (hexadecimal:
0A
, decimal:
10
). If this character is not sent, the device of the
SEFELEC
series does not process
the command received.
Check that this character is indeed added to the characters of the command sent.
The first command that must be sent is the REM command, the latter results in the
display of the icon of the links of a chain on the left hand side corner of the LCD
screen, the device is then ready to process the other commands.
Warning: the first REM command must not wait for the Xon character before it is
sent.
The device switches to REMOTE then seems to be blocked
Before sending another command, it is imperative to wait for the device in the SE-
FELEC series to report that it is available by the sending of the
Xon
character. If a
code arrives during the processing of the preceding code, it can cause incoherent
operation of the device or block it.
