Communication
NKK Switches’ LCD SmartSwitches and SmartDisplays.
Any computer, terminal, or other device that can communicate over the
RS232 line.
A PCB assembly that controls one or more logic boards and the switches
associated with them. It communicates with a host over the RS232 line.
A PCB assembly with “glue logic” for mounting switches. It is controlled by a
controller.
An eight bit hex value ranging from 00H to FFH (Decimal 0 to 255). The bit
format of a byte is: (B7 B6 B5 B4 B3 B2 B1 B0) where B7 is most significant
and bit B0 is least significant bit.
A four bit value ranging from 0H to FH. A byte consists of two nibbles.
A byte value representing a symbol.
There are two formats to transmit a byte:
Format
1. Hex format - A hex byte is transmitted without any change to it. [ xxH ] will
be used to denote this.
All commands and some data are sent by using this format.
2. ASCII HEX format - Each nibble of the byte is converted to ASCII code
and sent as a byte. [ xxAH ] will be used to denote this.
For example, the hex byte 5AH is transmitted in two bytes, 35H and 41H .
The ASCII value for 5 is 35H and the ASCII value for A is 41H .
All addresses and most data are sent using this format.
Address
A one byte value ranging from 01H to FFH representing the 255 memory.
