If you are not sure of the type of power service available, please contact your local power company. · Reliable earthing (grounding) of this unit must be maintained.
CMS-16 / CMS-8 User's Guide Figure 4.1: Terminal Block Assembly (DC Units Only) 4.1.2. DC Powered Units The DC terminal block features two bus inputs as shown in Figure 4.1. This allows the user to connect only one DC power source, or connect two DC power sources where the second source functions as a backup.
Hardware Installation 4.2.1. Default Baud Rate (Sw1, Sw2, Sw3) Option Switches one through three select the default baud rate for all CMS RS232 Ports. The default baud rate must match the rate your control device will use when communicating with the CMS. If the control device will communicate via modem, select a default baud rate that is compatible with the modem. 1 SW 2 3 Default Baud Rate D D D 9600* U D D 300 D U D 1200 U U D 2400 D D U 19.2K U D U 38.4K D U U 57.
CMS-16 / CMS-8 User's Guide 4.2.3. Default Response Message Format (Sw6) When commands are invoked, the CMS can respond with either verbose (English text) or terse (numeric / abbreviated) messages. Response messages are summarized in Section 11.2. After installation, the /P command can also set the response format to "none" (Quiet Mode). When Quiet Mode is selected, the unit will not send response messages.
Hardware Installation 4.4. Connecting the Network Cable The CMS Network Port is an RJ45, 10BaseT Ethernet Jack, for connection to a TCP/IP network. Connect your 10BaseT or 100BaseT network interface to the CMS-32 Network Port. The CMS features a default IP Address (192.168.168.168.) Providing that you are communicating with the unit from a node on the same subnet, this allows you to initially contact the CMS without first accessing the CMS command mode to define an IP address.
CMS-16 / CMS-8 User's Guide Figure 4.2: CMS Application Example (Model CMS-16 Shown) 4.6. Application Example The example in Figure 4.2 shows one of many possible installation configurations for the CMS. In this example, CMS-16 ports have been configured as follows: · Network Port: The Network Port allows telnet access by remote Supervisors and/or Users. When a telnet connection is established, the CMS will prompt the caller to enter a password.
Hardware Installation · Port 2 (Modem Port): An external modem has been installed at Port 2. This port has also been configured for Modem Mode, which allows definition of a modem reset string, initialization string, and hang-up string. When a caller contacts the CMS unit via modem, a password prompt will be displayed. If the Supervisor Password is entered, the CMS will permit access to Supervisor Level Commands; if a Port password is entered, the CMS will only recognize User Level Commands.

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. 7.1.1. Port Connection and Disconnection The CMS provides communication between devices without the requirement that both devices use the same communication parameters.
CMS-16 / CMS-8 User's Guide To Connect ports, proceed as follows: 1. Access the Command Mode. 2. Invoke the /C command to connect the desired ports. a) Resident Connect: To connect your resident port to another port, type /C xx [Enter]. Where xx is the number or name of the port you want to connect. The CMS will display the numbers of the connected ports, along with the command sequence that will be required in order to disconnect the two ports.
Operation 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 Timeout. Providing the Timeout feature is enabled, a No Activity Timeout will disconnect resident ports or third party ports. Note: Option 74 in the Port Parameters Menu determines how the DTR signal will react when the port disconnects. The DTR signal can either be held low, held high, or pulsed and then held high. 1.
CMS-16 / CMS-8 User's Guide 2. Third Party Disconnect: (Supervisor Mode Only) The /D command is issued from your resident port to disconnect two third party ports. For example, if your Resident Port is Port 1, a Third Party Disconnect would be used to disconnect Port 3 from Port 4. Note: The Third Party Disconnect method can be used to terminate a Telnet "Direct Connection" or an outbound Telnet connection. For more information, please refer to Section 8.2 and Section 8.4.
Operation 3. No Activity Timeout: Providing the Timeout feature is enabled at either connected port, the No Activity Timeout can disconnect Resident Ports, or Third Party Ports. Note: The No Activity Timeout also applies to Telnet "Direct Connections" and outbound Telnet connections. For more information regarding, please refer to Section 8.2 and Section 8.4.
CMS-16 / CMS-8 User's Guide 7.1.2. Defining Hunt Groups A Hunt Group creates a situation where the CMS will scan a group of ports and connect to the first available port in the group. Hunt Groups are created by assigning identical or similar names to two or more ports. Hunt Groups can be defined using Any-to-Any, Passive, Buffer, or Modem Mode Ports. Note that the Network Port cannot be included in Hunt Groups. 1. Access the Command Mode.
Operation 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". 2. Your resident port is Port 4. To connect to the first available Modem, access the Command Mode and type /C MODEM* [Enter]. Hunt Group Example 2: 1. Ports 3, 4, and 5 are Any-to-Any Mode ports.
CMS-16 / CMS-8 User's Guide 7.3. Buffer Mode Ports configured as Buffer Mode ports will collect data from the connected device and store it in the CMS's statically allocated memory. Each CMS port features a fixed length, fixed position data buffer. The Buffer Mode allows collection of data from various devices without the requirement that all devices use the same communication parameters (e.g. baud rate, parity, etc.). Notes: · Buffer Mode Ports cannot access the Command Mode.
Operation If the port's buffer is empty, the CMS will send a message which reads "Connected xx, Buffer Empty"; where "xx" is the port number. If the buffer contains data, the CMS will display a prompt that offers four options: · Next Screen: To scroll through data one screen at a time, press the [Space] bar. Each time the space bar is pressed, the next full screen of data will be sent. · Scroll All: To send all data without pausing, press [1].
CMS-16 / CMS-8 User's Guide 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. Telnet Capabilities 8.1. Network Port Numbers Whenever an inbound Telnet session connects to a CMS RS232 Port, or an outbound Telnet connection is initiated from a CMS RS232 Port, the Port Status Screen and Port Diagnostics Screen will indicate that the RS232 port is presently connected to Port "Nn" (where "N" indicates a network connection, and "n" is a number that lists the logical Network Port being used.) This "Nn" number is referred to as the logical Network Port Number.
CMS-16 / CMS-8 User's Guide 8.2. The Direct Connect Feature The Direct Connect feature allows you to initiate a Telnet session with the CMS and make an immediate connection to a specific RS232 Serial Port of the users' choice, without first being presented with the command interface. This allows you to connect to a discrete TCP port mapped directly to one of the CMS RS232 Ports. Direct Connect employs unique, pre-assigned TCP port numbers for each RS232 Port.
Telnet Capabilities 8.2.2. Configuration The Direct Connect Function is configured on a per port basis using the RS232 Port Configuration Menus (/P nn), item 15, "Direct Connect". The following options are available: 1. Direct Connect OFF: Direct Connect disabled at this RS232 Port. (Default) 2. Direct Connect ON - NO PASSWORD: The Direct Connect feature is enabled at this port, but no password is required in order to connect to the port.
CMS-16 / CMS-8 User's Guide Notes: · Password protection for the Direct Connect feature will only function if the Supervisor Level Password has been defined (see Section 5.4.) · If the Supervisor Mode has been disabled at the Network Port (Network Configuration Menu, Item 11 = "Deny"), then the Port Password must be entered in order to establish a connection to this port. If the Port Password is not defined, the connection will be refused.
Telnet Capabilities When establishing a Direct Connection to RS232 Port "x", the corresponding TCP port number must be used. If conditions are acceptable (e.g. Target RS232 Port must be free and properly configured), an immediate connection will be made, with one possible exception; password entry may first be required depending on current password configuration settings. Note: When a Direct Connect attempt fails because the RS232 Port is busy, the call is immediately rejected at the TCP level.
CMS-16 / CMS-8 User's Guide 8.2.4. Terminating a Direct Connect Session To terminate a Direct Connect session, use the client Telnet program's "disconnect" feature. The following will occur immediately upon a client initiated disconnect: 1. The Network port is disconnected from the RS232 Port. 2. The Network session is terminated. 3. The RS232 Port is put to sleep. Notes: · The Sequence Disconnect Command, which is defined via the Port Configuration menus (CMS User's Guide, Section 5.
Telnet Capabilities 8.4. Outbound Telnet Connections The CMS allows you to initiate a maximum of two simultaneous outbound Telnet sessions from the CMS Command Mode. This feature is available in both the Supervisor Mode and User Mode. 8.4.1. Password Protection In order to restrict User level access to the outbound Telnet function, a password can be defined via the Network Port Configuration Menu (/N), Item 19.
CMS-16 / CMS-8 User's Guide 8.4.2. Command Syntax When an outbound Telnet session is initiated, the following command syntax is used: /TELNET [port] [RAW] Where: ip_address is the desired IP address (required.) port is the desired port number (optional, default = 23.) RAW initiates the Telnet connection in Raw Socket Mode (optional, default = standard Telnet mode.

9. 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. Saved parameters can also be uploaded to other CMS units. This allows rapid set-up when several units will be configured with the same parameters.
CMS-16 / CMS-8 User's Guide 4. The CMS will send a series of ASCII command lines which specify the currently selected CMS parameters. The last line of the file should end with a “/G-00” command. When the download is complete, press [Enter] to return to the "CMS>" command prompt. 9.2. Restoring Saved Parameters This section describes the procedure for using your terminal emulation program to send stored parameters to the CMS. 1.
