Turbo rates is in use, the overhead rate is reduced by a factor of three, and therefore the response
time will be around 15 seconds.)
11.3 Setup Summary
To access a distant-end unit:
Step Task
1 Designate a Master/Slave pair: Master at the local-end, Slave at the distant-end.
2
On the local-end unit, enable framing and EDMAC, define the unit as MASTER,
and then enter the bus address. This is constrained to be ‘base 10' meaning that
only addresses such as 10, 20, 30, 40, etc, are allowed.
3
Choose a unique bus address for the distant-end. This should normally be set to
the ‘base 10' address + 1. For example, if the MASTER unit is set to 30, choose 31
for the distant-end unit.
4
On the distant-end unit, enable framing and EDMAC, define the unit as SLAVE,
and then enter the bus address. The orange EDMAC Mode LED should be
illuminated.
5
Set the local-end unit to RS485 remote control, and set the bus address of this
local unit. The orange Remote Mode LED should be illuminated.
6
Once the satellite link has been established, connect the M&C Computer, and
begin communications, with both the local and distant end units.
EDMAC modes are fully compatible with AUPC modes.
