Output Configuration
1. Communications Configuration
Communications parameters for the H663 series are field selectable for your
convenience. Please see Figure 1 (page 2, #8) for selector location. The
following parameters are configurable:
■
Parity: Odd, even or none
■
Wiring: Two or four
■
Baud Rate: 2400, 4800, 9600 or 19200
2. Address Configuration
Each ModBus device on a single network must have a unique address. The
switch block must be set to assign a unique address before the device is
connected to the ModBus RS485 network. If an address is selected which
conflicts with another device, neither device will be able to communicate.

CONFIGURATION
The values of each dip switch are as follows:
1=1
2=2
3=4
4=8
5=16
6=32
7=64
8=128
To determine an address you simply add the values of any switch that is on.
For example:
Switch number 4 has an ON Value of 8 and switch number 6 has an ON Value of 32. (8+32 = 40)
See Chart 2 on the following page for a pictorial listing of the first 63 switch positions.
or
H663 series can be addressed as any whole number between and including 1-247. Each unit is equipped with a set of 8 dip switches for addressing. See below.
