CD24-R8
The CD24-R8 can be accessed directly using Scream (File Setup
→
→
Com Ports). The default line speed for the DATA connector is 115,200
baud. This rate is suitable for all common usage scenarios and should
not normally be changed.
2.1.3 Single CD24-R8 with Ethernet connection
The ETHERNET connector on the CD24-R8 can be connected to your
LAN via a network hub or switch. Most modern PCs and laptops also
allow a direct connection between the CD24-R8 and the Ethernet port
without an intervening hub or switch.
The network interface is implemented using a Lantronix WiPort-NR
module. To configure the network settings, please see Chapter 4 on
page 11.
To view the digitiser's output in Scream, open the Network Control
window (
+
) and add a new TCP server on port 10,002.
2.1.4 Multiple CD24-R8s without an EAM-R – USB connection
Multiple CD24-R8s can be connected to a single PC or laptop using a
USB hub. The individual units will appear as separate COM ports and
can be accessed from Scream as described in section 2.1.1 on page 5.
If the PC does not recognise the CD24-R8 as a virtual COM port, you
can download drivers from http://www.ftdichip.com/Drivers/VCP.htm
The GPS receiver should be connected to only one CD24-R8. A GPS
“daisy-chain” cable is used to pass timing information to other units in
the rack.
The CD24-R8s are supplied with separate power supplies but, if a
suitable DC power source is available, a “daisy-chain” power supply
cable can be made up to run all the units from a single supply.
