Inter-Block Delay

For the PEN Emulation interface, data are sent to the Host in fixed size blocks of 20
characters each. The inter-block delay parameter allows setting a delay between each block
sent to the Host.

Network Parameters

Slave Address Range First/Last

These 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 in a single
network is 16, (including the Master if present). All cradles in the system must 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
page 45.
At system power-up, the Master searches for and initializes all the Slaves found in the valid
address range. During this phase the yellow LED on the Master cradle blinks. The time to
complete the start up procedure varies depending on the complexity 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 be operative and can collect data from all devices.

All Slaves must be powered up either before or together with the Master.
Slaves successively powered will not be recognized by the system even if
their address is in the specified range.
