Step Five: Install peripheral cabling

You can connect printers, terminals, modems (or any other sta ndard EIA232 device to be co ntrolled by appl ica tions on the computer) to the EPC/CON-16 concen trator by installing a cable between the peripheral and the concentrator.

On the peripheral end of the cable, the cable connector depends on the requirements of the peripheral. The EPC/CON-16 (or PORTS/Xem module) end of the cable must fit either an RJ-45 or DB-25 connector, depending on the model you have.

The pin assignments for each type of EPC/CON-16 connector are as follows:

What Next?

At this point the hardware installation for your EPC/X system is complete. However, sinc e the EPC/X adapter and the EPC/CON-16 concentrators must hav e softw are do wnload ed to their int ernal RAM before the y become functional, you must next install the software dri vers for your operating system.

This install ation guide describes how to plan your setup and install the EPC/X host adapter and conc entrator hardware.

Step One: Plan your setup

An EPC/X system can be set up in a variety of ways. Before you start your installation, be sure of the following:

Number of components.

and Xem modules onto one EPC/X host adapter (using both lines). It is a good idea to balance the number of connections on ea ch line. Having 12 concentrators and modules on one line, and 2 on the other , for example, may not make the best use of line resource.

Location of components.

concentrat ors can be located up to ten feet apart. (The daisy-chain cable that c omes wit h e ach Xem modul e a llows it to be st acked on t op of the concentrator to which it is attached via the EBI connector.)

If your installation calls for greater distances between concentrators, you can use twisted pair cabling in a maximum cumulative length of up to 2000 feet (600 meters) from the host adapter.

Note: The lengt h o f t wiste d pai r c ablin g a f fects the max imum data

transfer rat e that can be expec ted over the cable. The longer the length, the lower the rate. To maintain a baud rate of 10 Mbaud, the maximum cumulative twisted pair cable length cannot exceed 30 feet (9 meters).

You can also us e fiber optic cable (a specia l fiber optic convers ion option is available from Digi) that will allow a distance of up to 1.2 miles (2000 meters) from the adapter.

For even greater distances , you can attach a synchronous modem directl y to the adapter, and remotely locate concentr ators and Xem modules to a second synchronous modem.

Cabling.

Before beginning the installation, be s ure that you have the cables that you wil l nee d for the distances bet ween concentrators, as well as cables for the peripherals that you will be attaching to the concentrators and Xe m modules. EPC/X system concent r ators and PORTS/Xem modules are available with RJ-45 or DB-25 connectors for peripheral c abling. You will need to be sure that you have cables of the correct length and with the right connectors to properly attach the devices you want to us e with each concentrator or Xem module.

Power Requiremen ts.

Modem/Xem module) requ ires its own power supply. Befor e proceeding with installation, you s hould verify that adequa te line power is avail ab l e w h ere each con ce nt r at o r (and M od e m / X em) will be installed. Note that PORTS/Xem modules do not require power supplies when attached to an EPC/CON-16 concentr ator.

Additional information about the options available with the EPC/X system, such as s p ecifications and ca bling details, is provided on the CD-ROM that is packaged with the host adapter.

You can connect up to fourteen conce ntrators

Step Two: Install the EPC/X PCI host adapter

Before installing the EPC/X host adapte r, you shoul d do the following:

• Wear an ESD wrist strap to ground yourself while handling the adapter. If one is not available, discharge static electricity from your body by touching an unpainted metal surface, such as the computer’s chassis, prior to handling the adapter.

• Record the adapter serial number, which will enabl e Digi to provide you with better service, should the need arise.

The serial number label has this general format:

S/N: (S) XXX XXXXX

• Unplug power from the PC.

1. Remove the computer’s cover.

2. Locate an available PCI slot in your computer and remove the slot

plate.

3. Insert the adapter into the slot and screw the endplate to the computer chassis. The endplate must be scre wed into the computer chassis to remain in compliance with Part 15 of FCC rules.

4. Replace th e co mp u t er ’s cover.

5. Attach an EIA-422 cabl e to the co nnecto r of each li ne you will us e on

the adapter.

Step Three: Install concentrators and add-ons

1. Position concentrators and Xem modules (if any) at t he loc ation you have prepared according to the plan you developed in

Step One

2. Attach the cable from line l on the adapter to the connector label led

Continue cabling until all concentrators in the chain are connected.

3. Install a terminator plu g in the

trator in the chain.

4. Repeat steps 2 and 3 for Line 2 on the adapter (if you are using it).

5. To cable PORTS/Xem or Modem/Xem modules to the EBI bus of a

concentrat or, atta ch one end of an EBI cable to the tor on a concentrator and the other end to the add-on module. Continue similarly using the

connectors on the ad d-on mo dules until all the add-ons for a concentrator are cabled together.

6. Attach power supplies to the concentrators (and Modem/Xem mod-

ules).

7. Turn on power to the unit(s).

Step Four: Set the node numbers

Each concentrator must have a unique node number so the adapter can recognize it on the cha in. In general , you shoul d set the node num ber of a concentrat or ac cording to its relative position in the chain. F or example, the concentr ator c losest to the adapte r w ould be node 1 , the s econd would be node 2, and so on. To set the node number, do the following:

1. Wait until you see
