Only when using SEND/RECEIVE function
Select system in each channel in SEND/RECEIVE function
Select the method of each channel (instruction or data memory starting) on the parameter address 7700
to 7703(8) (3700 to 3703(8)).

2. When using connected channels => refer to page 10-2
In the SEND/RECEIVE function, the JW-22CM can transfer 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.
[Example 1] When all channels are used for the data memory starting method (using channel
alone)
When JW20H/30H is used
CH 0
7700(8)
80(H)
CH 1
7701(8)
81(H)
CH 2
7702(8)
82(H)
CH 3
7703(8)
83(H)
[Example 2] When channel 0 is used for the instruction method, and channel 1 to 3 are the data
memory starting method and used connected.
CH 0
7700(8)
00(8)
CH 1
7701(8)
81(8)
CH 2
7702(8)
81(8)
CH 3
7703(8)
81(8)
- In this case, channel 2 and 3 can not be used.
If values other than "00(H), 80 to 83(H)" are set, they will be ignored.
