Transparent Mode 10-2
The following examples 1 through 4 illustrate the application of the A2400
in the extended mode of operation. The A2400 in transparent mode allows
equipment from various sources to be added to a network of D series
modules. However the following rules must apply:
1. half duplex communications.
2. 10-bit data format.
3. The equipment must work on a command and response protocol
and that protocol must not interfere with valid D series prompts ($, #) or
the customer programmed prompt of another A2400 module that may
be on the same line.
4. In examples where more than several devices are to be on the
same line the devices must have their own channel address.
