CHAPTER 2: Overview 2. Overview The Remote Management Switch (part number SW555A or SW555AE) can be used for serial switching and as an AC power control system. A Remote Management Switch with Modem (part number SW556A-R2 or SW556AE— includes 56 kbps modem) is also available. See Figure 2-1. MANUAL Figure 2-1. The switch’s front and rear views. 2.
REMOTE MANAGEMENT SWITCH 3. Installation 3.1 Master and Switched Ports Connect the Remote Management Switch’s back-panel ports A through D to your RS-232 devices. Each port uses a DB25 subminiature connector and supports the leads shown in Table 3-1 for asynchronous communications. Table 3-1. DB25 connector supported leads.
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.
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. D C B A Master DTR RTS 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 Remote Management Switch’s top cover. The jumpers are located behind the B and D port connectors (see Figure 3-3).
CHAPTER 3: Installation 3.3 Internal Modem Option (SW556A-R2, SW556AE) An internal modem is included in two models of the Remote Management Switch. Part numbers SW556A-R2 and SW556AE incorporate 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. (See Figure 3-4.) The modem complies with FCC Class A and uses the standard AT command set.
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.
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).
REMOTE MANAGEMENT SWITCH Once you select a port, the switch will clear the screen and generate the following message: x Selected (x=the programmed name of the port) Enter ESC{PASSWORD}ESC to return to menu At this point, the master port is connected through to the port selected. The Remote Management Switch is passive to the messages sent between the master port and the port selected.

Entering new label name. 2) Password. The password is used for logging into the menu system and in every escape sequence.
CHAPTER 4: Operation 5) Lead Control. This selection determines whether control leads from the switched ports can be used to access the master port. The factory default is lead control disabled. Select Yes or No. 6) Command Response. The switch can send a response to escape sequences to let the operator know that the switch has taken place. The factory default is responses disabled. Select Yes or No to change the setting. 7) Modem or Terminal Mode. Sets the switch for either terminal or modem use.
REMOTE MANAGEMENT SWITCH 4.3 Escape Code Control The Remote Management Switch allows direct computer control using simple ASCII strings. These codes can control the port selection and relay operation. To access the switch for code control, enter the commands as shown below. To invoke the auto-rate detector, press the Escape key one or more times, until the switch responds with BLACK BOX READY.
CHAPTER 4: Operation Responses to Code Control commands are optional and set via the Programming menu. 4.4 Lead Control of Ports The Remote Management Switch can automatically select ports via control leads. You must set up this feature before using the switch. Any port can access the master by raising the RTS or DTR lead (jumper selectable) provided no other port is already connected by Menu, Manual, or Code Control. If another port is connected, the request is placed in queue.
