I AM HAVING TROUBLE GETTING PROPER COMMUNICATION BETWEEN LOOKOUT 5.0 AND AB SLC 5/03 PLC ON A 3002 VOICE GRADE LEASED LINE USING LEASED LINE MODEMS. I AM USING THE SERIAL PORT ON THE COMPUTER AND I HAVE CREATED AN AB SLC 5/03 DRIVER IN LOOKOUT FOR 1200 BAUD COMMUNICATIONS. EVERYTHING IS OK. SO I CREATED A SERIAL FILE TO VIEW THE ASCII DATA BEING TRANSMITTED IN AND OUT OF THE LOOKOUT. I DO SEE DATA GOING OUT AND TRYING TO GET BACK, BUT IT IS SCRAMBLED. THERE IS NO CONSISTANCY. SOME DATA GETS CHOPPED OFF. I RECEIVED ERROR MESSAGES "NO RESPONSE - NO ACK FOR OUR TRANSMISSION" AND "RECEIVED TNS DOES NOT MATCH". THESE ERROR MESSAGES TOGGLE DEPENDING ON HOW I ADJUST THE GAINS ON MY MODEM. I NEED HELP..... ANY ADVICE WOULD BE APPRECIATED. THANKS.
