Sharp JW-20CM, JW-20RS System, 1. When using 1 channel alone, 2. When using connected channels, Select system in each channel in SEND/RECEIVE function

“When PC is JW model and the SEND/RECEIVE function is used”

Select system in each channel in SEND/RECEIVE function

•Select the method of each channel (instruction or data memory starting) on the parameter address 007700 to 007703(8).

007700(8)	CH 0
007701(8)
	CH 1
007702(8)
	CH 2
007703(8)
	CH 3

1. When using 1 channel alone

Channel	Setting	System
	value (H)
CH 0	0 0	Instruction system
	8 0	Data memory starting system
CH 1	0 0	Instruction system
	8 1	Data memory starting system
CH 2	0 0	Instruction system
	8 2	Data memory starting system
CH 3	0 0	Instruction system
	8 3	Data memory starting system

2. When using connected channels

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.9 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 system (using 1 channel alone)

CH 0	007700(8)	8 0 (H)
CH 1	007701(8)
		8 1 (H)
CH 2	007702(8)
		8 2 (H)
CH 3	007703(8)
		8 3 (H)

[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.)

CH 0	007700(8)	8 0 (H)
CH 1	007701(8)
		8 1 (H)
CH 2	007702(8)
		8 1 (H)
CH 3	007703(8)
		8 1 (H)

If you enter values other than “00(H), 81(H) to 83(H)” the JW-20CM ignores the entry.
