Info

Setting the Message The message menu looks like the following: MESSAGE NO.1 MESSAGE LENGTH 40 0123466[0] Function MESSAGE NO. is defined as the following where “X” represents the phase setting: 0: Arbitrary message set from the external controller using the HP-IB capability. The data must be entered in units of words. Refer to “ [SOURce] : PAGing [ : FORMat] : CPOCSag I FLEX 1 FTD) :ARBitrary :DEFine , CNRl>, . . . , ” and “Using the Buffer Memory for the Arbitrary Messages” in Chapter 2. This arbitrary message buffer is divided into multiple segments by assigning START BATCH and STOP BATCH in the following menu: rFREQUENCY B ~~~ - AMlJlUDE START BATCH 000 STOP BATCH 127 I I I I The allowable ranges for both are 000 to 127. 1: Displays: 0123456 C-1 2: Displays: ABCDEFG [PI 3: Displays: TEST PAGING: POCSAG 4: Displays: ALPHANUMERIC 40CHARS TEST PAGING : POCSAG ellcodc44.cdr 5: Displays: 8888888888888888888888888888888888888888 for LCD test with 40 characters of “8”. 6: User-definable message, up to 40 characters long, set from the front panel. Enter numeric messages with the keypad. Alphanumeric messages require the (-1 (SHIFT) key to access the alphabetical characters (blue letters) above the keypad. If required alphabetical characters are not available on the front panel, send a message from an external Operation Reference 1 b-29
Function lb-30 Operation Reference controller over HP-IB. Refer to “ [SOURceI : PAGing C : FORMat] : CPOCSag I FLEX I FTD) :MESS : DEFine ‘string”’ in Chapter 2. MESSAGE LENGTH specifies the maximum number of characters that will be sent out and displayed in the message field. The allowable range is 1 to 40. After specifying the number of characters, press ljdB(mL) (ENTER) to save the new value. When the value of this parameter is equal to or greater than the length of the message, the whole message will be sent out. When the value of this parameter is less than the length of the message, only the characters specified by this parameter are output. (For example, if the MESSAGE NO. is 1(0123456[-1) and the MESSAGE LENGTH is 5, the message which is displayed and will be sent out is actually 01234.)
