REMOTE MANAGEMENT SWITCH 3. Installation 3.1 Master and Switched Ports Connect the Remote Management Switch’s ports A through D found on the rear of the unit to your RS-232 devices. Each port uses a DB25 subminiature connector and supports the following leads for asynchronous communications. Table 3-1. DB25 connector supported leads. Pin Designation 2 Transmit Data 3 Receive Data 4 Request to Send 5 Clear to Send 6 Data Set Ready 7 Signal Ground 8 Data Carrier Detect 20 Data Terminal Ready Remot

CHAPTER 3: Installation The four switched ports, A through D, are wired DCE (output data on pin 3, RD). The master port is wired as DTE. To directly connect a terminal device to the master port, you need a null-modem cable (see Figure 3-2). Control leads required vary from device to device. Consult your device’s operations manual for details on your specific needs. Figure 3-2. Null-modem connection. 9

REMOTE MANAGEMENT SWITCH 3.2 RTS/DTR Selection WARNING To avoid electrical shock, you MUST remove power to the Remote Management Switch BEFORE opening the top cover. Jumpers JP1 through JP4 let you select RTS (default) or DTR as the control lead used for lead control. To access these jumpers, disconnect the power source and remove the top cover of the Remote Management Switch. The jumpers are located behind the B and D port connectors (see Figure 3-3). Figure 3-3. Location of components. 10

CHAPTER 3: Installation 3.3 Internal Modem Option (SW556A, SW556AE) An internal modem is included in two models of the Remote Management Switch. Part number SW556A features a 33.6-kbps modem, while part number SW556AE incorporates a 56-kbps modem. Connect the modem to the dial line via an RS-232 to modular adapter (included). This adapter connects to the master port and to an RJ-11 modular jack. The modem complies with FCC Class A and uses the standard AT command set. Modular Adapter Figure 3-4.

REMOTE MANAGEMENT SWITCH 4. Operation 4.1 Four Modes of Operation You can operate the Remote Management Switch in four possible ways: menu selection, escape code sequences, lead control, and manual control. 4.1.1 MENU SELECTION By connecting to the master port, you can switch to any of the four ports (A through D) or operate any of the four relays. The menu system allows convenient naming of each port and relay, as well as allowing setup of all Remote Management Switch parameters. A login proced

CHAPTER 4: Operation The Remote Management Switch automatically detects the rate of operation, allowing connection at 300 bps to 115.2 kbps. Using the default speed will allow the fastest access to the unit. To invoke the auto rate detector, press the Enter key one or more times as needed. When the Switch detects the rate, it will respond with the security login prompt: Login > Enter the default security code (the default code is “TEST,” all caps, case-sensitive). Three incorrect attempts to ent

CHAPTER 4: Operation • Terminal mode: The Remote Management Switch does not monitor the connection status of the master port. This mode allows an unlimited number of login attempts. Each time it receives an enter key, the Switch issues a new login prompt. After three tries, the login prompt is suppressed to allow you to enter control codes. Use this mode for direct cable connections from a PC or terminal to the Switch. 8) Cycle Time. Sets the length of time in a relay Cycle command. This time is
