Burst Electronics VS8x8 - Manual (Page 13)

RS232 data in a multi unit (Mode 4) environment.
Example:
SP (sp) Puts all units to sleep
WK,01 (wk,01) Wakes up unit ID 1
SA12345678 Set All command for unit ID 1
SP (sp) Puts all units to sleep
WK,02 (wk,02) Wakes up unit ID 2
SA87654321 Set All command for unit ID 2
SP (sp) Puts all units to sleep
When VS8x8’s are in Mode 4, they always power
up in the Sleep state. Before any unit will respond
to RS232 commands, a Wake command must be
sent. Setting two or more VS8x8’s to the same ID
will control each unit together, but the data
returning to the computer will be jumbled.
