Á Power Cable Receptacle  Power Switch à RS232 PORTS: For connection to console ports on target devices.
3. Getting Started This section provides a brief overview of basic CMS capabilities, and describes simple tests that can be used to determine if the unit is operating properly . 3.1. Communication Parameters The Option Switches, located on the instrument back panel, select default operating settings.
3.3. System SetUp Ports In order to ensure access to important command functions, Ports 1 and 2 are designated as System SetUp Ports; the Supervisor Mode cannot be disabled at these ports. Ports 1 and 2 will always allow password protected access to all CMS command functions, even when the unit has been reset to the default state.
3. The Port Status Screen will be displayed, followed by the "CMS>" prompt, indicating that you have successfully accessed the Command Mode. If the "CMS>" prompt is not displayed, this may indicate a communication problem. Check the following: a) Cable Connection: Check the connection between the CMS and the PC.
b) Third Party Connection: Y our resident port (e.g. Port 1) issues a /C command to create a connection between two other ports. i. T o connect Port 2 to Port 3, type / C23 [Enter] . ii. While Ports 2 and 3 are connected, Port 1 will still recognize CMS commands.
4. Hardware Installation 4.1. Connecting Power to the CMS Unit The CMS is available in both AC and DC powered versions. When connecting AC or DC power to the CMS, proceed as follows: CAUTION: This device should only be operated with the type of power source indicated on the instrument nameplate.
4.2. Configure Option Switches When the CMS is shipped from the factory , the Option Switches are configured for 9600 baud, 8 Bits-No Parity , R TS/CTS handshaking, verbose command response, and command echo ON (all switches Down). These settings are compatible with most applications.
4.2.2. Default Handshake (Sw4, Sw5) The default handshake format must match the format your control device will use when communicating with the CMS. Option Switches 4 and 5 can select R TS/CTS (hardware), XON/XOFF , Both or None. Switch Default Handshake 45 D D RTS/CTS * U D XON/XOFF D U Both U U None * = Factory Setting 4.
4.4. Connecting Devices to the CMS 1. Access the Command Mode. 2. Determine which port will be used for connection to the new device (e.g. Port 3). 3. Check Buffer: T ype /S [Enter] to display the Port Status Screen. Check the "Buffer Count" column, which lists the amount of data stored in the buffer for each port.
· Ports 5, 7, and 9 (User Ports): The Port Password “COLOCA TION1” has been assigned to these three ports. If the CMS is contacted via the Network Port or Modem Port, and this password is entered at log in, User ’ s will only be able to review status and connect to the devices attached to Ports 5, 7, and 9.
5. Configuration 5.1. Access to the CMS Command Mode When the CMS Command Mode is active, commands can be invoked to select parameters, and connect or disconnect ports. Note: Command Mode cannot be accessed from a Buffer Mode Port, Passive Mode Port, or any port that is currently connected to another CMS port.
5.2. System SetUp Ports As discussed previously in Section 3 of this User ’ s Guide, Ports 1 and 2 are designated as System SetUp Ports. Ports 1 and 2 will always permit password protected access to Supervisor Level command functions, even when the unit is reset to default parameters.
After the Supervisor Password has been defined (via the System Parameters menu), the CMS will display a password prompt whenever you attempt to access the command mode. If the correct Supervisor Password is entered, the CMS command mode then starts up in Supervisor Mode.
5.4. Defining the Site ID and Supervisor Password Before configuring individual ports, the Site ID and Supervisor Password should be defined. The Site ID is used to denote the location or name of the CMS unit, and the Supervisor Password is used to restrict access to sensitive commands.
5.5. Port Configuration 5.5.1. Configuration Conventions When responding to prompts, invoking commands, and selecting items from the port configuration menus, note the following: · T o select an item from a Port Configuration menu, key in the number and press [Enter] .
5.5.2. Port Modes The CMS offers four dif ferent port operation modes; Any-to-Any Mode, Passive Mode, Buf fer Mode, and Modem Mode. The Port Modes function as follows: · Any-to-Any Mode: Allows communication between connected ports.
The Port Configuration menu offers the following options: 1. Port Name: (Up to 16 characters, Default = undefined). 2. Password: (Up to 16 characters) Defines the Port Password for this port. Note that identical Port Passwords are generally assigned to several ports.
7. Port Mode: Defines the operation mode for this port. Note that Ports 1 and 2 cannot be configured for Passive Mode or Buffer Mode. (Default = Any-to-Any Mode). When Any-to-Any , Passive, or Buffer Mode is selected, the unit will display the DTR Output prompt (Figure 5.
8. Supervisor Mode: Permits or denies port access to Supervisor Mode. When enabled (Permit), and the valid Supervisor Password is entered, the port will be allowed to invoke Supervisor Level commands. If disabled (Deny), the port may not enter Supervisor Mode, even when the Supervisor Password is entered.
11 . Timeout Disconnect: Enables and selects the T imeout Period for this port. If enabled, and the port does not receive or transmit data for the specified T imeout Period, the port will disconnect. When the port is set for Any-to-Any Mode, Passive Mode, or Buffer Mode, the default setting for this item is “OFF”.
5.5.4. Network Port Configuration Menu In order to communicate with the CMS via network, the IP Address, Subnet Mask, and Gateway Address must first be defined using the Network Parameters Menu. If desired, this menu also allows you to implement IP Security features, which can restrict access based on the user ’ s IP Address.
The Network Parameters menu offers the following options: 1. IP Address: Defines the IP Address for the CMS unit. T ype 1 press [Enter] , and follow the instructions in the submenu. (Default = undefined). 2. Subnet Mask: Defines the Subnet Mask for the CMS unit.
13. Sequence Disconnect: Enables/Disables and configures the Resident Disconnect command. This prompt offers the option to either disable the Sequence Disconnect, select a three character format, or a one character format. (Default = Three Characters).
5.5.5. Implementing IP Security The CMS can be configured to restrict unauthorized IP addresses from T elneting to the unit. This allows the user to grant T elnet access to only a specific group of IP addresses, or block a particular IP address from gaining access.
Example 1: Deny access to all hosts except 192.1.1.5: Security Mask #1: 255.255.255.255 Mask #1 Action: Deny Security Mask #2: 192.1.1.5 Mask #2 Action: Permit Since 255 is a wild card, Mask #1 blocks all IP Addresses. Mask #2 then specifically grants access to 192.
5.6. Copying Parameters to All Ports The /CP command (Copy Port Parameters) provides a convenient means for selecting similar parameters for all CMS RS-232 ports. When the /CP command is invoked, the unit will display a menu which allows you to select port communication parameters, and then copy them to all CMS RS-232 ports.
T o select common parameters for all CMS RS-232 ports, proceed as follows: 1. Access the CMS command mode. If the password prompt is displayed, key in your Supervisor Level Password. 2. At the command prompt, type /CP and press [Enter] , the menu shown in Figure 5.
6. The Status Screens The CMS Status Screens display the connection status and communication parameters for the sixteen RS-232 ports and the Network Port. There are four different types of status screens; The Port Status Screen (/S), the Port Diagnostics Screen (/SD), the Network Status Screen (/SN), and the Port Parameters Screens (/W).
As shown in Figure 6.1, The Port Status Screen lists the following items: · Name: The user-defined name for each port. · Password: The user-defined password for each port. Note that actual passwords are not displayed; this column will read either “undefined” or “defined”.
6.2. The Port Diagnostics Screen (/SD) The Port Diagnostics Screen provides more detailed information about each port, including the port name and communication parameters. T o display the Port Diagnostics Screen, access the command mode and type /SD [Enter] , the screen will appear as shown in Figure 6.
· Baud: The baud rate selected for each port. · COM: The Data Bits, Parity , and Stop Bits selected for each port. For example, “8N1” indicates Eight data bits, No parity , and One stop bit. · HS: The handshaking (flow control) mode for each port.
6.4. The Port Parameters Screens (/W) The /W command displays more detailed information about an individual CMS port. Rather than listing connection information for all ports like the Port Status Screens, the Port Parameters screen lists all defined parameters for a specific port.
The /W command uses the following format: /W[P] xx [Enter] Where: P Is the command option to display port passwords. Note that when this option is included (e.g. /WP 5 ), the Port Parameters Screen will display the Port Password, if defined. (Supervisor Mode Only).
7. Operation 7.1. Any-to-Any Mode Any-to-Any Mode Ports can be connected to other Any-to-Any , Passive, Buffer , or Modem Mode Ports by accessing Command Mode and issuing the /C Command. All ports can be configured for the Any-to-Any Mode. Note that the Network Port is always configured for Any-to-Any Mode.
T o Connect ports, proceed as follows: 1. Access the Command Mode. If the Password Prompt is displayed, enter your Supervisor or Port Password. 2. Invoke the /C command to connect the desired ports. a) Resident Connect: T o connect your resident port to another port, type /C xx [Enter] .
7.1.1.2. Disconnecting Ports There are three different methods for disconnecting ports, the Resident Disconnect, the Third Party Disconnect, and the No Activity T imeout. Providing the T imeout feature is enabled, a No Activity T imeout will disconnect resident ports or third party ports.
3. No Activity Timeout: Providing the T imeout feature is enabled at either connected port, the No Activity T imeout can disconnect Resident Ports, or Third Party Ports. a) RS232 Ports: T o configure the Timeout Feature for the RS232 Ports, invoke the /P command to display the Port Configuration Menu for the desired port as described in Section 5.
Hunt Group port names must be unique. Otherwise, ports with similar names will also be included in the Hunt Group. Hunt Group Example 1: 1. Ports 1 and 2 are Modem Mode ports, and modems are installed at both ports. Port 1 is named "MODEM1" and Port 2 is named "MODEM2".
7.3.1. Reading Data from Buffer Mode Ports T o retrieve data from Buffer Mode Ports, you must first determine which port buffers contain data. T o check port buffers for stored data, access the Command Mode and type /S [Enter] to display the Port Status Screen.
7.4. Modem Mode In addition to allowing data transfer , the Modem Mode also provides additional functions specifically related to modem communication. A Modem Mode Port can perform all functions normally available in Any-to-Any Mode. The Modem Mode is available to all CMS ports except the Network Port.
8. Saving and Restoring Configuration Parameters After the CMS has been properly configured, parameters can be downloaded and saved as an ASCII text file. Later , if the configuration is accidentally altered, the file with the saved parameters can be uploaded to automatically reconfigure the unit without the need to manually assign each parameter .
8.2. Restoring Saved Parameters This section describes the procedure for using ProComm to send stored parameters to the CMS. 1. Start your terminal emulation program and access the CMS Command Mode; if the password prompt is displayed, enter the Supervisor Password.
9. Upgrading CMS Firmware When new , improved versions of the CMS operating firmware become available, the “Upgrade Firmware” function can be used to update the CMS unit. Updates can be uploaded via Setup Ports One and T wo, or via the Network Port.
6. Incomplete Upload: If the upload is interrupted, times-out, or if the file is corrupted during transfer , the CMS will display a screen which asks for user confirmation before proceeding. T o proceed, type 1 and press [Enter] , then return to Step 4 above.
10. Command Reference Guide 10.1. Command Conventions The commands described in this section conform to the following conventions: · Slash Character: Most CMS commands begin with the Slash Character ( / ).
