3. Using the RS-485 port on the ControlCenter keyboard: keyboards can be daisy-
chained and then connected to the DigiMux unit.
NOTE: Only one ControlCenter keyboard can operate with power supplied via the
DigiMux RJ-11 port. The additional keyboard(s) must have their own power
supplies.
Each DigiMux unit is set with an RS-485 ID address that enables the remote keyboard
to connect to it. In general, no two devices on the same RS-485 bus should have the
same ID address, so the ID assignments must be unique. The DigiMux default setting
is 9. To change the RS-485 port setting for each additional unit, see
Administrator Setup
on page 77.
Also note that the ControlCenter
TM
keyboard must be set to the baud rate of the
DigiMux unit. The DigiMux default baud rate is 4800 baud. See
RS-485 Port Settings
on page 82 for more information. For information about ControlCenter
TM
keyboards,
see Appendix G: Using ControlCenter 200/300 Keyboards on page 136.
