3 Installation and Commissioning

Hardware Installation

The Communication Processor must be installed into two spare slots

of a MOD HUB series ARCNET modular active hub. Refer to the

MOD HUB series User Manual for detailed information on installing

the MOD HUB. With the power off on the MOD HUB, remove any

filler plates and install the Communication Processor into the hub

and hand tighten the knurled screws. At least one additional

expansion module (EXP) must reside in the MOD HUB along with

the Communication Processor. For example, an EXP-CXS 4-port

coaxial star expansion module could be used to connect to the

Metasys N1 ARCNET subnet. Once an appropriate expansion

module and the Communication Processor are installed, the unit is

ready for configuration.

Configuring the Metasys Ethernet Router

The Communication Processor, on which the Metasys Ethernet

Router program resides, is actually a DOS computer with an

Ethernet port, ARCNET port, TCP/IP stack, BIOS and a flash disk

which emulates a disk drive. The router program has been preloaded

at the factory, but it must be configured. To aid in this process,

Planning Forms have been provided in Appendix A.

Note: Unlike previous versions of the Metasys Embedded Router,

the configuration program (CONFIG.EXE) cannot be run

from DOS — it can only be called from within the main

program during the boot-up procedure.

Monitor and keyboard functionality has been redirected to the two

DB-9 connectors (COM1 and COM2) located on the front of the

Communication Processor. Attach a short null-modem cable from

COM1 to a COM port on either a laptop or desktop computer

running a terminal emulation program like HyperTerminal. Set the

program for 19.2 kbps, 8 bits, no-parity and no hand shaking. (A

pinout of a null modem cable and more information on

HyperTerminal can be found in Appendix C).

Once the terminal emulator is ready, turn on the power to the MOD

HUB which houses the Communication Processor. You will notice

that the MOD HUB RECON light is on and the TIMING light is off.
