4 Trouble Shooting
Table 15: Trouble Shooting
Error Possible Reason Solution
No characters are received via the
interface/the Ecotec E3000 does not
answer. Wrong cable Please use a 1:1 cable, (NO null-modem cable, also called cross-over
cable!).
Problems with flow control Deactivate flow control in PC/PLC or use cable according to the wiring
diagram in Section 2.
Wrong COM-Port used at PC. Select correct COM-Port.
Wrong interface parameters (Baud rate,
Data bits, Parity, Stop bits) Check if interface parameters (Baud rate, number of data bits, parity bit
and number of stop bits in the Ecotec E3000 and PC / PLC match).
Wrong protocol selected in the Ecotec
E3000. Select correct protocol in the Ecotec E3000.
PC uses an USB-RS-232 converter. In general the Ecotec E3000 will also work with an USB-RS-232-
converter. However, these often cause multiple difficult to track
problems (driver, flow control.) Please test your PC program on a “real”
RS-232 interface first preferably. Especially with USB-RS-232-
converters it is often helpful to use a cable according to the wiring
diagram in Section 2.
Serial interface of PC is (still) occupied
with a different program . Check if other programs (e.g. a synchronisation software for your hand-
held computer) uses the serial interface. It is also possible that an
already closed program has not released the interface again yet. In this
case a restart of the PC will help.
The Ecotec E3000 replies with
“unreadable” characters. Wrong interface parameters (Baud rate,
Data bits, Parity, Stop bits). Check if interface parameters (Baud rate, number of data bits, parity bit
and number of stop bits in the Ecotec E3000 and PC / PLC match).
Wrong protocol selected in the Ecotec
E3000. Select correct protocol in the Ecotec E3000.
Ecotec E3000 does not reply / Ecotec E3000
replies after several command with “E10” “Carriage Return” at the end of the
command is missing. Finish all commands with “Carriage Return” (ASCII 0dhex / 13dez).
Ecotec E3000 replies with “E06”. Control via RS-232 not enabled in the
Ecotec E3000. Enable control via RS-232 (see submenu CONTROL LOCATION ).
Ecotec E3000 replies with error message to
the first command only, following
commands are interpreted correctly. Receiving buffer of the Ecotec E3000 was
not empty before sending the first
command (e.g. by plugging in the RS-232
cable during operation) In the ASCII protocol the Ecotec E3000 has not time out function
which will empty the receiving buffer automatically. Therefore, the
buffer should be emptied before the first command by sending of “ESC”,
“^C” or “^X”.
