SeaI/O Manual 43
After the Get command is executed, the “Module Description” frame will display the model type,
description, firmware version number, interface, and I/O type. In the example shown, the
module found at slave ID 247 is a SeaI/O-420 module with a USB (Modbus RTU) interface. The
“Set Settings” and “Change Slave ID” buttons will also be enabled for this module.
After a successful Get operation, additional tabs may be displayed in MaxSSD, depending on the
found device model. These tabs display device I/O and allow easy configuration for all SeaMAX
supported devices.
The “Broadcast to Multiple Modules” checkbox, along with the “Set Settings” button can be used
to change the baud rate and parity on multiple SeaI/O modules at once. This function only
works with SeaI/O modules connected together via the pass-through connectors.
MaxSSD broadcasts a set data rate and set parity command to all devices on the RS-485 bus,
but only those modules listening at the current baud rate will be able to receive and respond.
For example, if you have five SeaI/O modules chained together and two are set to 9600 bps and
no parity and three are set to 115.2k bps and the PC is set to 9600 bps, only the two modules
set to 9600 bps will receive the broadcast set data rate and parity message.
