[Example 2] When channel 0 is used for the instruction system, and channel 1 to 3 are the data
memory starting system and used connected.
(In this case, channel 2 and 3 can not be used.)
1. When using 1 channel alone
In the SEND/RECEIVE function, the JW-20CM can send and receive a maximum of 256 bytes
of data for each channel. For the data memory starting system, the amount of communication
data can be increased by connecting channels.
Set the data amount with 8X(H) (X is 0 to 3, determined depending on which channel is used
for the connector.)
When using connected channels, these should be consecutive channels. For example,
channel 0 and 1, or channel 2 and 3 can be connected to each other, but channel 1 and 3 can
not be connected to each other.
