You can address the IRC remotely via one of the following paths:
●
"
SER
": Computer via RS-232 serial interface
●
"
LAN
": Computer via Ethernet (LAN cable)
If you use a combination of these control devices and paths, some of the following
operating modes can result in special cases:
●
MAN
only: no special case
●
IRC + SER
: no special case
●
IRC + LAN
: no special case
●
Combined as follows:
–
IRC + SER
and
MAN
–
IRC + LAN
and
MAN
These combinations establish a special case:
For the computer to detect the presence of the MAN unit, the chamber must open
and close once via SER or LAN. In the combined mode of operation, SER/LAN and
MAN can send contradicting commands, activating pneumatic mechanisms both
for opening and closing the drawer. This conflict makes the chamber remain in its
current state, which is not dangerous for the operator, nor does it damage the
chamber. For further operation, MAN will be the master over SER or LAN, and
there is no restriction in operation.
We recommend avoiding this conflict by the following procedure:
To change the mode of operation
1. Disconnect the chamber from power.
2. Establish a combination of control devices and paths.
3. Activate the chamber as described in
Chapter 7.1, "Activating the Chamber"
4. After power-up, use MAN as the first control device for sending a door command.
This procedure ensures that the computer detects the
assigns it the role of the master controller.
