The "Remote AB-M Switches" connect a common device on port A to either of its slave ports B/C/D/S. "S" is a logical security port (no connection). The Matrix version connects any port to any other port or multiple ports. The X2 version has more of a security or rebooting flavor. It connects/disconnects two 8-wire connections, such as two LAN connections.

The AB-M provides the same basic peripheral sharing functions as the familiar manual A/B/C/D switch boxes that the industry grew up with. These switches however, can also be controlled remotely, opening the door to other network switching applications such as back-up, security, resource allocation, etc., in addition to the peripheral sharing functions.

They are available in Three or Four port models with:

  • RJ-11 connectors for telephone phone line switching applications (4 wire)
  • RJ-45 connectors for switching Ethernet, Token Ring or T1 circuits (8 wire).
  • DB-9(25)/RJ-45 filtered adapters are available for 8 wire RS-232 switching applications.
The port connections can be selected manually by simply pressing the "select button". Remote control can be initiated through the serial port of an adjacent PC (an RS-232 Filtered Adapter is required) or with the addition of one of CPS's Remote Controllers (SP-RRC, 3P-RRC or N-RRC). Note: A "Master PC" connected to Port A can also control its own "switch to ports" through a second serial port.

The Controllers provide the desired type of communications interface (phone line or TCP/IP). They also add password security, and the ability to share a phone line as well as other programmable features. The controllers are the same as those that are used for the CPS rebooting products. They follow the same flexible "Base Unit + Controller" concept.

The AB-M Base Switch is also dip switch addressable. Up to 31 of them can be daisy chained from one Controller or from each port of a multi-port telephone line Controller. As an example a 3P-RRC (three port) could support up to 93 AB-Ms (31 per port). An eight port controller is being planned (up to 248 AB-Ms). They connect to the controllers, and to each other, with standard RJ-11 telephone cables at a combined distance of up to 2000 feet. Any of the addressable CPS AC power control units can also be intermixed within the same "daisy chain" (IPN or APB) for additional application flexibility.

Command Examples
A typical command to connect port (B)-2 to port A from the serial port of a PC may look like:

* AD 2#
* is an attention command for the AB-M since there is no controller to wake it up.
AD is the address of the Switch if daisy chained (01-31).
2 is the Port that is going to be connected to port (A)-1
# terminates the command.

If this command were sent through a Touch-tone controller you would precede it with the commands for the controller and it would look like this:

#8 PASS 1 AD 2#
------------------------Controller Command--------------------------------------
#8 is the attention command for the controller that you are using.
PASS is the controllers password (consult the controller manual)
1 is the port on the controller. (for multi-port controllers)

------------------------AB-M Command (same)-------------------------------------
AD is the address of the Switch if daisy chained (01-31).
    Note: if multiple switches have the same address,
    they will all take the command.

2 is the Port that is going to be connected to port (A)-1
# terminates the command.

Note: Do not use spaces they are used for clarification only.

These Touch-tone commands can be entered manually or appended to the AT dial string.

 


AB-M X2
The X2 version is more geared toward security and rebooting applications. It connects/disconnects two eight-wire connections, such as two LAN connections, under RS-232 or Controller control.

It is used primarily to disconnect and reconnect servers on a LAN or to reset the power on wireless LAN Access Points that use PoE (Power over Ethernet). It makes an ideal running mate in this rebooting application since it can also share the "daisy chain" with addressable AC Power Base Units (IPNs) or Auto Push Boards (APBs) that can be used to reset or cycle the AC power on the associated routers or servers.
