CDM-625A Advanced Satellite Modem MN-CDM625A
Appendix H Revision 4
H–4
H.3 Setup Summary
To access a distant-end unit:
• Designate a Master/Slave pair: Master at the local-end, Slave at the distant-end.
• 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.
• 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.
• On the distant-end unit, enable framing and EDMAC, define the unit as SLAVE, and then
enter the bus address.
• Set the local-end unit to RS-485 remote control, and set the bus address of this local unit.
The orange “REMOTE” Mode LED on the modem front panel should be lit.
• Once the satellite link has been established, connect the M&C User PC, and begin
communications with both the local and distant end units.
EDMAC modes are fully compatible with AUPC modes.
