LINK Systems LinkNet I - Manual (Page 41)

LinkNet
A.1
manual rev 2.1 March 25, 1999
If the OIT software version is older than
version 2.0, the OIT and motherboard software
MUST both be changed at the same time.
Appendix A - Upgrading Link Equipment
Many new Link products will ship with network
support - but products produced before September
of 1998 may need to have software and/or hardware
upgrades. New equipment may also need software
upgrades to take advantage of new features both
network and non-network related - it’s a good idea
to check with Link on the status of any new
software upgrades when installing the Link network.
The following sections explain how to do the
software and hardware upgrades.
A.1 General Chip Changing Rules
Changing the software on Link equipment is
accomplished by swapping electronic chips called
EPROMS (called “chips” in the rest if this section).
These chips are plugged into sockets on various
circuit boards on the equipment and can usually be
identified by the label that gives the chip type and
version number. No special equipment is necessary
to change a chip but it is necessary to observe a few
precautions and rules:
@
Make sure that power to the system is OFF
when changing chips. Failure to observe this
precaution can result in damage to the
equipment.
@
Gently pry a chip from its socket using a small
blade screw driver (or chip remover if available).
Be sure to place the screw driver between the
socket and the chip - Not between the socket
and the circuit board!
@
When inserting a chip into its socket, make sure
the notch on the end of the chip is aligned with
the notch in the socket. The unit will not work
if the chip is inserted backwards and damage to
the chip may result.
@
When inserting a chip into its socket, make sure
that no pins are bent under the chip and that all
pins are in the socket.
A.2 System 1100 Tonnage Monitor Upgrade
Procedure
The System 1100 will require upgrading if the
existing software is older than version 3.3 on the
operator interface board (the circuit board mounted
to the door of the unit) or version 2.6 on the
motherboard (underneath the channel 1 & 2 dual
channel card in the bottom of the unit). OIT
software versions 2.0 and up will display the OIT
software version and the motherboard software
version for about 5 seconds when the unit powers
up. Older software will only display the OIT version
at power-up - the channel 1 & 2 dual channel card
must be removed to check the motherboard software
version.
A.2.1 System 1100 OIT Software Upgrade
Procedure
@
Review section A.1 for chip changing rules!
@
Turn off the power to the System 1100.
@
Open the front door of the System 1100
enclosure.
@
Using Figure A.1, locate the software chip on
the circuit board mounted to the System 1100
enclosure door and remove it.
@
Install the new software chip labeled 1100-OIT
in the socket. All software versions prior to
V2.0 had different chips for 2 channel and 4
channel tonnage monitors, but V2.0 or higher
works with both 2 and 4 channel OITs.
