The OMM-2500 modular matrix provides RS-232 serial communication. The simplest way to
control OMM-2500 over RS-232 is using embedded software in Windows OS, HyperTerminal.

not available on Win 7.):

▪
Select Start > Programs > Accessories > Communications > HyperTerminal.
▪
Enter a name and choose an icon in Connection Description window and click OK.
▪
In Connect To window, ignore the Country, Area Code and Phone Number fields but select
available COM port of PC to be connected to OMM-2500 then, click OK.
▪
In COM Properties window, set the parameters as below:
Bits per second (baud rate): 115200 (115200 is default baud rate of OMM-2500)
Data bits: 8
Parity: None
Stop bits: 1
Flow control: None
[Note] Bit per second of Hyper Terminal should be set as same as baud rate of OMM-2500.
▪
Click OK to save the parameters.
▪
Go Start > Programs > Accessories > Communications > HyperTerminal, then new icon
will be shown. Then select it to launch Hyper Terminal.
