Delay Time Programming 6-2
Figure 6.1 Programmable delay times.
As described in figure 6.1 the communications sequence assumes a host
computer communicating with a module on the RS-485 bus through the
A2400.
In an idle condition, when no data is present on the communications lines,
the A2400 turns its RS-485 transceiver to receive mode and monitors
activity on the RS-485 bus. When data is detected on the RS-232 input, the
A2400 bus arbitrator immediately turns on the RS-485 driver and transmits
