Serial Commands
All serial commands are applicable to the MSV0502 and MSV0804. Both matrices follow the same
command structure with the exception of command strings that designate ii for input assignment and oo
for output assignment. For the MSV0502, ii would be 01 – 05 and oo would be 01 – 02, while the
MSV0804, ii would be 01 – 08 and oo would be 01 - 04.
Addressing Commands
If the switcher is being used in RS-232 mode (no other devices connected in parallel) there is no need to
assign an address for this unit. If you are using multiple Inline products connected in parallel to a single
serial port using RS-422 or RS-485 communications, you will need to assign an address for each unit.
The factory default for the unit is no address. The address for the unit must be between 01 and 98.
Address 00 is a broadcast address and all units on the buss will perform the action commanded;
however, they will not issue any responses.
To open communications to an addressed device, you must send a [CCxx] command. All other devices
on the buss will ignore commands until addressed.
COMMAND DESCRIPTION
[ADDRxx] Assigns an address to the unit, 01 to 98. Address 99 is reserved for future
products.
•
Where xx = 01 - 98
[ADDR@] Removes an address from the unit. This is the factory default, and is the typical
way to use the switcher when in the RS-232 mode
[ADDR?] Query unit for a pre-assigned address.
[CCxx] Connects controller to the addressed unit. 00 is a broadcast address thus all
connected devices will perform commands. This command is to be used in
conjunction with the [ADDRxx] command string.

Where
o xx = 01 - 98
