Check the baud rate, hand shaking, parity, stop bit, etc. when configuring the serial
communications software. The required settings are listed in the
RS-232
Communications
section above.
Make sure there are no bent pins in the ends of all the data cables
Make sure the device is powered. The Green LED should be on.
If the computer is a laptop running on batteries, try plugging in the power. Some
laptops disable the serial ports when running on batteries.
Make sure a null modem adaptor or cable is not being used.
Make sure the correct adaptors(if any) are being used. Refer to the pinouts in the
RS-
232 Communications
section above.
If the problem was encountered when trying to control the device with custom
software, try using one of the demo programs from the Zaber website to verify that
the hardware is functioning properly.
Two or more devices both respond to commands sent to device 1.
Most devices are shipped with their device number set as 1. If you connect the devices
through Zaber Console, you will be prompted to renumber them. If you aren't able to install
and open Zaber Console, send the
renumber
(
T:2
) command in the software you are using to
set all of the device numbers to different values.
The Yellow LED comes on briefly when sending a command, but the device does not move
and does not reply.
Check baud rate, hand shaking, parity, stop bit, etc. are set as per the
RS-232
Communications
defaults.
The device numbers may not be what is expected, issue a
renumber
(
T:2
) command. Make
sure that the computer does not transmit anything else while the devices renumber.
If using the Binary Protocol, check the following:
6 bytes are transmitted and that the device number and command are valid.
The software does not transmit any control characters such as line feed and spaces.
That the serial port is not configured with a termination character (it often defaults to
linefeed).
If problems are encountered when using custom software, try using one of the demo
programs from the Zaber website to verify that the hardware works.
The device does not behave as expected when software sends it a series of commands.
The computer might be set to Unicode. This is common for languages that use non-Latin
based characters. Go to Control Panel/Regional and Language Options/Advanced. Select a
language for non-unicode programs. This should be English or another Latin based character
language.
Check what is being sent out of the serial port.
stackoverflow.com
has a list of some tools to
monitor serial ports.
In Binary mode, the device does not send replies but otherwise works.
Auto-reply might have been disabled via
T:101
.
Send a
system restore
(
T:36
) command.
