1. Introduction The AFS-16 is a versatile switching system, designed for applications that require automatic routing of analog or digital signals between a common jack and "A" and "B jacks. The AFS-16 is ideal for switching RS232, RS422/485, Ethernet/UTP or telephone lines. The system consists of a Card Rack, one Power Supply Module, one Control Module, and up to 16 Circuit Modules. Each Circuit Module is capable of switching all 8 pins of a common RJ45 jack between Jack "A" and Jack "B".

For example, ]S or ]P 02. [Bold Font] 1-2 Text set in bold face and enclosed in square brackets, indicates a specific key. For example, [Enter] or [Esc].
2. Unit Description The AFS-16 consists of a frame unit, one Power Supply Module, one Control Module, and up to sixteen Circuit Modules. 2.1. The Power Supply Module The Power Supply Module, shown in Figure 2.1, provides AC power used by the Control Module and Circuit Module(s). The AFS-16 will always include one Power Supply Module. Figure 2.
A F S - 1 6 Us e r ' s Gu i d e 2.2. The Control Module The Control Module, shown in Figure 2.2, coordinates switching of the individual Circuit Modules. The Control Module includes a Master A/B Gang Switch, status LEDs, and an RJ-11 jack for connection to your PC, control device or external modem. An AUX jack is provided to allow connection to a monitored line and optional external alarm. The AFS-16 always requires one Control Module. Figure 2.

A F S - 1 6 Us e r ' s Gu i d e 2.3. The Circuit Module The AFS-16 can accept up to sixteen Circuit Modules. Each Circuit Module includes a common jack, jacks for "A" and "B" paths, and a Manual A/B switch. Figure 2.3: The Circuit Module 2-4 À A/B Switch: Each A/B Switch can be manually switched, or activated by commands sent to the Control Module. The A/B Switch can also be operated by the Control Module's Master A/B Switch. Á Â Ã Ä "A" Connector "C" Connector: For connection to a common line.
3. Installation 3.1. Initialization Prior to first time installation, the AFS-16 should be initialized using the following procedure: Note: The initialization procedure will clear all memory, set parameters to default values, and sequentially toggle each switch card. 1. Connect the AFS-16 power cable to an appropriate power source. 2. Hold the Control Card Toggle Switch in the "A" position (UP) while turning AC power ON. 3. Release the Toggle switch after approximately 3 seconds.
A F S - 1 6 Us e r ' s Gu i d e Figure 3.1: Control Module Jumpers (Not to Scale) 3.3.1. RS232 Port Baud Rate Jumper The RS232 Port can be set for 1200, 2400, 9600 or 19.2K bps using Jumper J1 (Figure 3.1). · 1200 bps: Place jumper at position 1. · 2400 bps: Place jumper at position 2. · 9600 bps: Place jumper at position 3. · 19.2K bps: Place jumpers across positions 1 and 2. 3.3.2. Master A/B Gang Switch Jumper Jumper J2 (Figure 3.1, Item 4) enables/disables the Master A/B Gang Switch.
Section 3: Installation Figure 3.2: Circuit Card Jumpers (Not to Scale) 3.4. Circuit Module SetUp The A/B Switch Jumper (Figure 3.2) enables/disables the individual Circuit Module's response to the Master A/B Gang Switch. When disabled, the A/B Switch will not be effected by the Master A/B Switch. To disable response to the Master A/B Gang Switch, place the jumper in the right hand position.

4. SetUp and Configuration 4.1. Communicating with the Control Module The AFS-16 can be controlled by simple ASCII commands sent to the Control Module RS232 port. To communicate with the unit, first start your communications program (e.g. ProComm). If your PC is connected directly to the RS232 port, the AFS-16 will then be ready to accept commands. Note however, that the "AFS>" prompt will not appear until after a command has been invoked.
A F S - 1 6 Us e r ' s Gu i d e 1. Location ID: Can be appended to the Notify Message and may also be sent at any time to verify the identity of the unit. Up to 32 characters. Any character may be used except ], quotes and null. 2. Password Mode: Enables/Disables the password feature. When enabled, the "Enter Password" prompt will appear when the unit is contacted via modem. 3. Password: Allows the user to define the modem password (Default = FALLBACK). 4.

5. Operation The AFS-16 offers three different methods for switching A/B paths: 1. Manual A/B Switching: Manual A/B Switches are used to initiate switching of one or more Circuit Modules. 2. Code Activated A/B Switching: ASCII commands are sent to the Control Module to initiate switching of one or more Circuit Modules. 3.
A F S - 1 6 Us e r ' s Gu i d e 5.2. Code Activated A/B Switching The AFS-16 will also switch A/B paths in response to simple ASCII commands sent to the Control Module. To switch A/B paths, invoke the ]T command using the following format: ]T N,P [Enter] Where: N Is the number or name of the desired Circuit Module. Enter an Asterisk (*) to apply the command to all installed Circuit Modules. To apply the ]T command to more than one Circuit Module, enter numbers for additional modules separated by commas.
Section 5: Op e r a t i o n When configuring a Circuit Module for the Monitor Mode, note the following: · Only one Circuit Module may be configured for the Monitor Mode at a given time. · The Monitor Mode can provide automated A/B switching of up to sixteen Circuit Modules, or can send a Notify Message without switching A/B paths. · When an external modem is installed at the Control Module RS232 Port, the Notify Message can be defined as an AT command.

6. Application Examples 6.1. Monitoring Signal Drop and/or Power Loss In this application, the AFS-16 will monitor the DTR signal from a data device. If the signal drops or the data device loses power for more than one minute, the unit will automatically switch modules 4, 5, 6, and 7 to path "B". In addition, the AFS-16 will also send a notify message to the Control PC. Figure 6.1: Monitoring Signal Drop 1. Pull Input Level Low: Remove the Control Module from the frame unit.
