Demo exercises using Card 2: Devices 0 and 1: ADK-2130mPCIe-2F
While card 1 is currently executing the b, k, t, n, B, K, N, c, C, a, A demonstration above, repeat the same
sequence in the second command shell exactly. Observe that both command shells demonstrate traffic is
proceeding on Channels 0 and 1 in both shells.
Demonstrating the Holt Mini PCIe RT with an external BC
Any one of the four RT’s can be used with an external BC tester. Choose the desired channel and set the RT
address to match the BC message using command ‘9’. Connect the external BC to a bus coupler and connect a
stub from the bus coupler to the BNC connector on the optional Holt breakout board. See AN-551 for proper
bus connections.
To change the RT terminal address, press ‘9’ BEFORE enabling the RT. If a RT was enabled by a ‘b’ , ‘B’, ‘c’ or ’C’
command use command ‘4’ to reset the card first. The program first prompts for the channel number 0-4
followed by the RT address value.

Enable the RT with a corresponding ‘c’, ‘C’, ‘b’ or ‘B’ command depending on which RT and channel is used.
Enable ‘k’ or ‘K’ and ‘t’. The RT is ready for BC command reception. Make sure the external BC message tester
is set for the corresponding RT address or the message will be ignored. Traffic data display using the ‘t’ command
is optional but is recommended when first learning the card. BC message transaction occurs whether or not the
‘t’ command is used since ‘t’ just enables the ability to display the data on the console.
