3. Indicates a Unit as shown in the following table.
Unit
Setting
PC
00
SYSMAC NET Link, SYSMAC LINK,
or Controller Link Unit
$10 to $1F: Unit numbers 0 to F
$FE: The local Unit
SYSMAC BUS/2 Master, BASIC Unit,
or Personal Computer Unit
$10 to $1F: Unit numbers 0 to F
SYSMAC BUS/2 Group-2 Slave
$90 to $CF:
Unit 90+10
×
Master address
4. Values of $01 to $7E indicate nodes 1 to 126. Set to $FF to send to all nodes,
$00 to send data within the local PC.
5. Designates the length of time that the PC retries transmission when bit 15 of
C+3 is OFF and no response is received. The default value is $0000, which
indicates 2 seconds. The response function is not used when the destina-
tion node number is set to $FF, broadcasting to all nodes in the network.
6. Transmissions cannot be sent to the PC executing the send.
Set the destination node number to $FF to send the data to all nodes in the des-
ignated network or to $00 to send to a destination within the node of the PC exe-
cuting the send. Refer to the SYSMAC LINK System Manual or Controller Link
System Manual for details.
Word
Bits 00 to 07
Bits 08 to 15
C
Number of words (1 to 256 in 4-digit hexadecimal, i.e., $0001 to $0100)

Bits 12 to 15:
Set to 0.
C+2
Destination unit address
3
Destination node number

C+3
Bits 00 to 03:
No. of retries (0 to 15 in
hexadecimal,
i.e., $0 to $F)
Bits 04 to 07:
Set to 0.
Bits 08 to 11:
Transmission port number
($0 to $7)
Bit 12 to 14:
Set to 0.
Bit 15:
ON: No response.
OFF: Response returned.
C+4
Response monitoring time ( $0001 to $FFFF = 0.1 to 6553.5 seconds)

Note
1. Set the destination network address to $00 when transmitting within the lo-
cal network. In this case, the network of the Link Unit with the lowest unit
number will be selected if the PC belongs to more than one network.
2. Set the BASIC Unit interrupt number when a BASIC Unit is designated.
3. Same as for SYSMAC NET Link Systems. See note 3 above.
4. Values of $01 to $3E indicate nodes 1 to 62. Set to $FF to send to all nodes,
$00 to send data within the local PC. In a Controller Link System, the des-
tination node number can be set to values of $00 to $20 or $FF.
5. Designates the length of time that the PC retries transmission when bit 15 of
C+3 is OFF and no response is received. The default value is $0000, which
indicates 2 seconds. The response function is not used when the destina-
tion node number is set to $FF, broadcasting to all nodes in the network.
6. Transmissions cannot be sent to the PC executing the send.
Precautions
C through C+4 must be within the values specified above. To be able use of
SEND(192), the PC must have a SYSMAC NET Link Unit, SYSMAC LINK Unit,
or Controller Link Unit mounted.
Do not change the control data during a transmission (i.e., while the correspond-
ing Port Enabled Flag in A502 is OFF).
Note Refer to page 101 for general precautions on operand data areas.
