6.2 Transmission Speed and Address
All instruments which are connected to the same bus (RS485), or work with the same interface
(RS232), must be set to the same transmission speed. Transmission speed is set to 9600 baud at
the factory. Speed can be changed to 200, 300, 600, 1200, 2400, 4800, 9600 or 19200 baud with
the bAUD parameter.
If several instruments are operated with the same interface, a different address must be selected at
each instrument. Address 1 is selected for all instruments at the factory. Different addresses can be
selected with the Adr parameter. See programming instruction in chap. 5.1 page 12.
6.3 Transmission Protocol and Message Formats
Protocols for serial interfaces RS232 and RS485 are the same and demonstrate the following char-
acteristics:
Data bits: 8, parity: even parity check, stop bits: 1
Message Formats
Notes: The required waiting time between two messages is equal to max. 1 ms. The check sum
ranges from the address, up to the last byte prior to the check sum.
• Status inquiry: With this message the computer can inquire as to whether or not a DIGEM is con-
nected to this address, and whether or not it is functional.
• Reset: This message resets all stored values, and the tare value if one is selected. Other values
remain unchanged.
• Parameters inquiry: see table below
• Setting parameters: see table below
