RS232 Port Parameters

The Port Parameters Menus are used to conﬁgure the CMS-6R4's serial RS232

Ports, and allow you to assign a name to each port and select parameters such

as the baud rate, parity and handshake mode. To access the Serial Parameters

Menu, proceed as follows:

• Web Browser Interface: Click the "Setup" button to access the Setup

Menus, and then click the "Port Parameters" button. The Port Parameters

Menu will be displayed as shown in Figure 5.14.

• Text Interface: Type

/P n and press [Enter] (where n is the number or

name of the port that you wish to conﬁgure.) The Port Parameters Menu

will be displayed as shown in Figure 5.15.

Note:

Port 7 is the Internal Modem port; the Port Mode for this port

is set to "Modem" and cannot be changed. To conﬁgure the Modem

port, either select port 7 via the Web Browser Interface, or access the

Text Interface and type

/P 7 [Enter].

As shown in Figure 5.14 and Figure 5.15, the Port Parameters Menus allow

you to deﬁne the following parameters:

• Port Name: Assigns a name to this port. (Default = undeﬁned.)

Note:

The Port name can be up to sixteen characters long, and cannot

include control characters, forward slashes (/), asterisks (*), or space

characters. The ﬁrst character of the Port Name must be a letter of the

alphabet.

• Baud Rate: Baud Rate for this RS232 Port. (Defaults: Port 1 through

Port 6 = 9,600 bps; Port 7 (Internal Modem Port) = 57.6 Kbps.)

Note:

When this setting is changed, the new baud rate will not be

applied until the user exits and then re-enters command mode.

• Bits/Parity: The data bits and parity setting for this port.

(Default = 8 Bits, No Parity.)

• Stop Bits: The Stop Bits setting for this port. (Default = 1 Bit.)
• Handshake Mode: Selects the handshake format for this port;

XON/XOFF, RTS/CTS (hardware), Both, or None. (Default = RTS/CTS).
