In a network with a JACE controller, the JACE is connected directly to the master device via an RS232 cable. The JACE takes on the control functions of the master device, interrogating the network for information.
While all slave devices must be compatible with a communication rate of 300 baud, this driver supports multiple baud rates, which means that all slave devices, sharing the same network, can communicate with the master at the most efficient baud rate for the device.
