Serial Commands

All serial commands apply to the MSX1616 and MSX3216. Both switchers follow the same command structure with the exception of command strings that designate ii for input assignment. For the MSX1616, ii would be 01 – 16 while the MSX3216 ii would be 01 - 32.

Addressing Commands

If you use the switcher 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 must assign addresses 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, the unit 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 they are addressed

COMMAND

[ADDRxx]

[ADDR@]

[ADDR?]

[CCxx]

DESCRIPTION

Assigns an address to the unit, 01 to 98. Address 99 is reserved for future products.

•Where

oxx = 01 - 98

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

Query unit for a pre-assigned address.

Connects controller to the addressed unit. 00 is a broadcast address thus all connected devices will perform commands. Use this command in conjunction with the [ADDRxx] command string.

•Where

oxx = 01 - 98

Note: This command string is case sensitive.
