I just finished an application where I needed to communitcate a Zebra printer and computer running labview code. Computer connected to port 1 (mode hostlink), printer connected to port 2 (mode RS232). First to all, you need to make sure all settings matches on both devices connected, then, and even more important, cables should be the correct ones. (remember some Omron PLC requires power off-power on to use the new downloaded settings). Host link cable should be as per Omron specifications. Check it firts. Second, I advice you do download a serial port monitor and emulator for your PC. I used RealTerm (I really like it), then, check you are receiving exactly what you are sending from the PLC. A good tip is to go DM area and select view as ASC, then write something there and send it to you PC checking with Realterm. Make sure you have all there before you start checking your hostlink coding. Hope this helps. David Chavarria Automation and Industries - Costa Rica -

Yes! Great support. We have figured it out. Attaching correct cable for any further reference. Thanks also to Mike Walsh from Omron who worked directly assiting me on this matter.

Hi I have been trying to send a command string to a zebra printer thru port 2 on cpm1h with no success so far. I have the plc correctly setup matching settings with zebra as 9600,8,1,N. Using a hostlink cable I can send the string to my laptop (using realterm or hyperterminal) and capture it , then from laptop, using a null cable, send it to printer. Printer prints ok. The problem: either host link or serial null does not work from plc to printer. Does someone have experience doing this job with these devices and can enlight me on what cable should be used or any other trick related?
