Omnia-6ex Use and Operation Manual – V: 1.20
17
The Omnia-6EX also contains a third PC Memory Card slot that is used to load software for the Front Panel. The
slot is located under the top cover on the right-hand side of the Front Panel circuit board and is normally un-
occupied. Please do not insert or remove any PCMCIA cards from this slot without the direct assistance of Telos /
Omnia customer support. Make sure the AC power is off and disconnected from the unit before removing the top
cover and removing or replacing a card.
Important Note 1: The PC Cards used in the Omnia-6EX are not generic PCMCIA cards that can be bought in any
local computer store. They are cards that are specially qualified by Omnia specifically for this product. If you need a
backup card, please contact Omnia Customer Support to purchase an additional card. Inserting a card of unknown
origin risks damaging the Omnia, the cards, or both, and doing so will void your warranty!
Important Note 2: If you wish to operate the Omnia-6EX using a PCMCIA type modem, you must use the
available modem card from Omnia. Other modem cards are NOT qualified for use at this time. We cannot provide
technical support for any other modem card. External modems are a different case. Typically, any external Hayes
compatible modem may be connected to the rear-panel serial port. See Chapter 6 for more details on the Modem and
the Remote Control Software.
Note: The rear panel PCMCIA Memory Card must remain in the top slot unless you are prompted by the system to
remove it. Randomly removing the PC Card without system instruction may cause unpredictable operation and PC
Card data damage.
AC Environment
The Omnia-6EX subsystem is microcomputer-based. Therefore, it requires the same clean AC environment as any
modern computer system does. Even though the Omnia-6 is equipped with quite robust internal AC input transient
suppression, we recommend that external transient suppressers/voltage regulation or an Uninterruptible Power
Supply (UPS) be employed. This recommendation becomes even more important when installing the processor at a
transmitter site, where there can be heavy transients on the power lines. These unwelcome events can be caused by
anything from load switching to lightning strikes on a nearby tower. Therefore, we ask that you give your AC power
environment and installation practices thorough consideration before plugging in your Omnia6-HDFM unit.
