Toggle to

YES

and press ENTER if you plan to use DH-485 in your

application. To temporarily disable DH-485, toggle to

NO

and press

ENTER. To permanently disable DH-485, the hardware must be
re-configured (see Configuring the IMC-S/23x in the Installation and
Hookup section of this manual).

Maximum Node Address

Enter the highest address of any device on the DH-485 network for
the maximum node address. This is the highest address which will be
polled as devices pass the token among masters on the DH-485 network.
The smaller the maximum node address, the faster the throughput on
the DH-485 network, since no time is spent polling devices which do
not exist.

Network Node Address

Enter the desired address of the motion controller on the DH-485
network for the network node address. The specified address must
be less than or equal to the specified maximum node address. If not,
the message

is displayed and you must enter a new network node address.

Baud Rate

Toggle to the baud rate of the DH-485 network to which the motion
controller is connected. Both 19,200 and 9,600 baud are available.
Unless necessary for some other device, always use 19,200 baud for
fastest communication.

Token Hold Factor

Toggle to the hold factor you want (1, 2, 3, or 4). Selecting the
default of 4 gives the IMC-S/23x the largest time slice for sending
and receiving.
