Before you start
The CHM software allows you to monitor the connected chargers and to
program the receivers inserted into the chargers.
Before you can work with the CHM software:
! The CHM requires operational RS 485 ports. These can be the ports of
an RS 485 card built in the computer or made available via an RS 232-
to-RS 485 interface converter.
Note:
If possible, use an RS 485 card (or an RS 232-to-RS 485 interface
converter) recommended by Sennheiser for connecting the chargers
to the Charger PC (see “Recommendations concerning the RS 485
interface” on page 5-46).
! The driver for the RS 485 ports must be installed and the Windows
Device Manager must recognize the RS 485 ports as being
“operational”!
! The chargers must be correctly connected to the serial RS 485
interfaces of the computer by means of suitable cables.
Note:
When using self-made cables for connecting the chargers to the
Charger PC, observe the correct wire assignment of the cables (please
contact your local Sennheiser dealer for assistance).
! A string (daisy-chain) with a maximum of 32 chargers can be
connected to each RS 485 interface. Each charger has ten charging
compartments (slots) for inserting the receivers. A maximum of 320
charging slots per string can thus be accessed.
! The CHM can manage a maximum of 16 strings (i.e. 5,120 receivers).
! The receivers must be inserted completely into the charging
compartments.
