AXlink Status LED

The green LED (CR1) on the front end of the card indicates AXlink status, as follows:

 

• One blink per second indicates power is active and AXlink communication is

 

functioning.

 

• Two blinks per second indicate that the devices specified in the master program do

 

not match the devices found.

 

• Three blinks per second indicate an AXlink communication error.

 

• Full on indicates the following:

 

•There is no AXlink control or activity, but power is on. (For example, another

 

AXC-EMmay have control of AXlink.)

 

•The Axcess program is not loaded.

 

 

To ensure the integrity of your Axcess program, you can use two AXC-EMs,each loaded with the same program. Should the primaryAXC-EM'scontrol of AXlink be interrupted, the secondaryAXC-EMwill automatically take control.

Setting the RS-232Communications DIP Switch

Use the 8-positionDIP switch to set the communication parameters. Set the parameters with the combination of ON and OFF positions. The following table describes the communications DIP switch settings:

Product Information

Installation

To install the AXC-EM:

Static electricity can damage electronic circuitry. Before handling the card, discharge any accumulated static electricity from your body by touching a grounded metal object.

1. Hold the card by the tab end and slide the card into one of the first two slots of the frame. If it is the primary card, insert it into slot MC1.

If it is the secondary (backup) card, insert it into slot MC2.

Make sure the card is correctly positioned in the guide slot.

2.Gently push the card in until it is firmly seated in the card connector slot. You do not have to disconnect the power to the CardFrame when you install the card. When power is applied to the card, the green LED lights.

3.Load the Axcess program.

AXLink Wiring

Connect the wiring from the CardFrame to the external AXlink devices, as shown in FIG. 2.

Product Information

Replacing the Battery

There are two lithium batteries on the AXC-EM.The batteries protect the memory on theAXC-EM.While the DC power is on, the batteries are not used. The battery life is five years. At the time of installation, record when you need to replace the batteries.

When you replace the batteries, you may do so one battery at a time without loss of data in memory.

All data in memory will be lost if you are not timely in replacing the batteries.

As a precaution, be sure you have access to a backup of your Axcess program. If your program was loaded with the Source-Sendoption on, retrieve a copy of the source code from theAXC-EM.If it was loaded with theSource-Sendoption off, be sure you obtain a copy of the program before replacing the batteries.

To remove and replace the batteries:

1.Discharge static electricity from your body.

2.Remove the card from the CardFrame.

3.Lift the handle and remove one battery from its socket.

4.Carefully slide the new battery under the handle and into the socket.

5.Reset the card in the CardFrame to apply power to the card.

6.Follow steps 1 through 5 to replace the second battery.

Improper handling of a lithium battery can be hazardous.

Never recharge, disassemble, or heat the battery above 212°F (100°C).

Never solder directly to the battery or expose the contents of the battery to water.

Dispose of used batteries according to the manufacturer's instructions.

Replace the battery with a battery of the same type.

Upgrading the Memory Chips

The AXC-EMhas two 256 Kb RAM chips. You can upgrade with two 1 Mb RAM chips(FG-072).To install the RAM chips:

1.Remove the battery.

2.Remove the 256 Kb RAM chips currently in sockets U1 and U2 (FIG. 3).

Pin 1

Pin hole 3

FIG. 3 Removing the 256 Kb chip

3.Remove the 1 Mb RAM chips from their anti-staticpackaging. Save the packaging for storing the 256 Kb RAM chips.

4.Align the notch end of one of the 1 Mb RAM chips with the notch on one of the sockets. Then, align Pin 1 of the RAM chip with Pin 1 of the socket (FIG. 4).
