8.3 Master Station Status
This is the first master station screen which is displayed at power-up
The
Master Tag
is an identity tag which can be configured by the user.
The
Status
line indicates the loopback status and the ESD input state.
The loopback state is displayed as:
LB OFF
- loopbacks are all off
LB ON
- loopbacks are in use, i.e. there is a loop fault
LB busy
- "message" during loop re-configuration only. The message will be one
of the following;
1) LBbusy:Wait for LB 1 (first wait for loopbacks to come on)
2) LBbusy:Find FCUs on A (finding FCUs on port A)
3) LBbusy:Test Loop (testing for complete loop)
4) LBbusy:Find FCUs on B (finding FCUs on port B)
5) LBbusy:Wait for LB 2 (second wait for loopbacks to come on)
6) LBbusy:LBs off on A (removing loopbacks from port A)
7) LBbusy:LBs off on B (removing loopbacks from port B)
N.B. -
The normal sequence for a fault free loop would be 1-2-3. A sequence for a break in the loop
anywhere except at port A or port B, would be 1-2-3-4-5-6-7. Note that some of the phases may be very
quick, particularly at higher baud rates, and so may not be displayed as the LCD update rate is about twice a
second.
