REFERENCES1655.2.5 Inter-Block DelayFor the PEN Emulation interface, data are sent to the Host in fixed size blocks of 20characters each. The inter-block delay parameter allows setting a delay betweeneach block sent to the Host.5.3 NETWORK PARAMETERS5.3.1 Slave Address Range First/LastThese parameters define the valid addresses for the Slave cradles on the network.Valid values are in the range 0 to 1999. However, the maximum number of cradles ina single network is 16, (including the Master if present). All cradles in the systemmust have different addresses.To reduce system boot time, it is recommended to number the Slaves consecutively,while it is not necessary that the Master cradle address is contained in the range.The network addresses correspond to the radio addresses, see par. 4.7.At system power-up, the Master searches for and initializes all the Slaves found inthe valid address range. During this phase the yellow LED on the Master cradleblinks. The time to complete the start up procedure varies depending on thecomplexity of the network but is typically between a few seconds to a few minutes.Start up cannot be interrupted. At the end of this procedure the system will beoperative and can collect data from all devices.All Slaves must be powered up either before or together with theMaster. Slaves successively powered will not be recognized bythe system even if their address is in the specified range.CAUTION5.3.2 Network Warning MessageThe Master cradle can transmit warning messages to the Host regarding somenetwork errors./*Slave xxxx not responding*/: when the Master can no longer communicatewith the specified Slave previously identified at start up./*Frame out of sequence for terminal xxxx*/: if a reader is sending datapackets out of sequence. This can happen if there are transmission problemson the network (either connection or communication), or if the reader hascorrectly transmitted data to a device not on the network (reader configurationerror).
