Transmission statement configuration
Transmission statements sent and received between the GOT and the host unit are classi-
fied into the following three formats. Type 1 and Type 2 can replace each other. When the
sum is not attached to a command, use Type 1. When the sum is attached, use Type 2.
Type 1 (without the sum)
When a command is Type 1, a response to it will be Type 1 or Type 3.
Type 2 (with the sum)
The targets of the sum are the entire text and ETX. The result of addition (excluding STX) is
converted into an ASCII code and sent. The sum consists of the upper digit and the lower
digit in this order.
When a command is Type 2, a response to it will be Type 2 or Type 3.
Type 3
This type of format consists of only one character. This format is used for responses (ACK
or NAK) and interrupt codes.
The table below shows characters available in statements. Interrupt codes include unused
codes.
