MODULE #7 - PROGRAM SERIAL COMMUNICATIONS
Several programmable parameters must be programmed before serial
communication can occur.
BAUD RATE
Select one of the baud rates from the list to match the baud rate of the
printer, computer, controller, etc.
“bAud” < > “300” - 300 baud
“600” - 600 baud
“1200” - 1200 baud
“2400” - 2400 baud
UNIT ADDRESS NUMBER
Toallowmultipleunitstocommunicateonthe20mAloop,differentaddress
numbers must be assigned to each unit. If only one unit is on the loop, an
address of “0” may be given, eliminating the need for the address command.
“
“AddrES” < > “0” to “99”
PRINT REQUEST FUNCTION
A selection of print operations can be programmed. A print operation
occurs when a print request is activated via E1-CON (TBA #4) or optional
E2-CON (TBA #8),ora“P” command is sent from a terminal via the serial
communicationsoption. Ifthe optionto whicha particularprintcode applies
is not installed, then that parameter will not be printed.

printed (ex. *000127 positive overflow, -*00127 negative overflow). If the
temperature exceeds the range of the unit, the print-out will show
“OLOLOL”.Ifthesensoropens,theprint-outwillshow“ULULUL”.Forthe
negative direction or shorted, the print-out will show “SHOrt”.
“Print” < > “0” - input signal
“1” - input signal, peak, valley and offset
“2” - input signal, alarm 1 and alarm 2
“3” - input signal, alarm 1, alarm 2, hysteresis 1,
hysteresis 2, peak, valley, and offset
“4” - totalizer
“5” - input signal and totalizer
“6” - input signal, totalizer, peak, valley, and offset
“7” - totalizer, alarm 1, and alarm 2
“8” - input signal, totalizer, alarm 1, and alarm 2
“9” - input signal, totalizer, alarm 1, alarm 2,
hysteresis 1, hysteresis 2, peak, valley, and
offset
FULL OR ABBREVIATED TRANSMISSION
When transmitting data, the IMY can be programmed to suppress the
addressnumber,mnemonicsandsome spaces,ifdesired,byselecting“NO”.
A selection of “NO” results in faster transmission. This feature may be
helpful when interfacing with a computer. When interfacing to a printer, a
“yES” response is usually desirable.
“FULL” < > “yES” or “NO”
An example of full and abbreviated transmission is shown below:
2 INP -125.7F < CR><LF> Full transmission
-125.7 < CR><LF> Abbreviated transmission
