CDM-Qx/QxL Multi-Channel Satellite Modem with DoubleTalk™ Carrier-in-Carrier® Revision 7

EDMAC Channel MN/CDMQX.IOM

10–3

10.3 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, 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, then

enter the bus address. The orange EDMAC Mode LED should be illuminated.

• Set the local-end unit to RS-485 remote control, and set the bus address of this local unit.

The orange Remote Mode LED should be illuminated.

• Once the satellite link has been established, connect the M&C Computer, and begin

communications, with both the local and distant end units.

Note: EDMAC modes are fully compatible with AUPC modes.
