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
