Serial Port Receive Data
Module Properties Dialog Box 18 Max Number of Receive Characters 0…200 In Simultaneous mode, the total number of channel 0 characters plus
channel 1 characters cannot exceed 200.
Ch1RxStartMode 19 Receive Record Start Mode 0…2 0 = ignore, 1 = exclude, 2 = include start delimiter
Ch1RxStartDelimiter 20 Receive Start Delimiter
(1)
0…127/255 0…0x7f (0…127) for 7-bit data
0…0xff (0…255) for 8-bit data
Ch1RxEndMode 21 Receive Record End Mode 0…2 0 = ignore, 1 = exclude, 2 = include end delimiter
Ch1RxEndDelimiter 22 Receive End Delimiter
(1)
0…127/255 0…0x7f (0…127) for 7-bit data
0…0xff (0…255) for 8-bit data
Module Production Data
Ch1RxPadChar 23 Pad Character
(1)
0…127/255 0…0x7f (0…127) for 7-bit data
0…0xff (0…255) for 8-bit data
Ch1RxByteSwapMode 24 Receive Swap Mode 0…2 0 = disabled, 1 = 16-bit, 2 = 32-bit
Ch1RxByteHandshakeMode 25 Master Handshake Mode 0…1 0 = master/slave handshake, 1 = produce immediate
CH1RxMessageTimeout 26 Message Time Out 0…65535 0 = none, 1 to 65535 ms
Serial Port Transmit Data
Module Properties Dialog Box 27 Max Number of Transmit Characters 0…200 In Simultaneous mode, the total number of channel 0 characters plus
channel 1 characters cannot exceed 200.
Ch1TxEndMode 28 Transmit Record End Mode 0…2 0 = ignore, 1 = exclude, 2 = include end delimiter
Ch1TxEndDelimiter 29 Transmit End Delimiter
(1)
0…127/255 0…0x7f (0…127) for 7-bit data
0…0xff (0…255) for 8-bit data
Ch1TxByteSwapMode 30 Transmit Swap Mode 0…2 0 = disabled, 1 = 16-bit, 2 = 32-bit
(1) To enter values 128…255, use this conversion formula: Desired Decimal Value - 256 = Entered Decimal Value. For example, for an ASCII character value of 128, 128 - 256 = -128.
