Page 4: Introduction
The RT-ANA unit is an interface converter that accepts CAN messages from the RT3000 and converts them to analogue voltages. The RT-ANA has up to 16 analogue output channels with a range of ±10V. The RT-ANA uses precision 16-bit DACs and precision op-amp drivers to ensure the highest levels of accuracy can be achieved.

LED state. CAN Running. The LED will flash Orange/Off every 100 CAN messages (100 Orange then 100 Off). Since the RT3000 updates at 100Hz and there are 4 CAN messages per update, the LED will cycle with a frequency of 2Hz.
Page 9: Configuration
Configuration There are two configuration parameters that may need changing by the user before operation begins. These are the CAN baud rate (so it matches the RT3000 and the other devices on the bus) and the fast-update mode. To configure the RT-ANA a serial terminal program is required. Windows comes with HyperTerminal, but other suitable programs can also be used.

Page 11: Command Syntax
RT-ANA User Manual Figure 3. RT-ANA Configuration Output at Start-up At Start-up the Dev Id is the version of software running in the RT-ANA unit. This may be required when contacting Oxford Technical Solutions for support. The user commands that the RT-ANA responds to are listed in Table 5, below.
Page 12 SAVECONFIG command or they will be forgotten when the power is removed. CONFIG command. The CONFIG command is used to list the settings in the RT-ANA box. The command will list all the configurations, not just the ones for the user. Do not change any configurations apart from the ones described here.
Page 13 RT-ANA User Manual CANBAUD command. The CANBAUD command is used to change the baud rate settings of the RT-ANA. This setting does not become active until the RT-ANA is next powered on. Syntax CANBAUD <RATE> Valid values for <RATE> are listed in Table 6, below.
Page 14 If a system samples the low- latency RT-ANA output at 100Hz then the timing is only known to 10ms. If it samples the fast-update RT-ANA output then it knows the timing to 0.6ms. For some applications the improved timing is more critical than the additional delay.
Page 15: Connections
RT-ANA User Manual Connections The RT-ANA should be connected to the RT3000 CAN bus as shown in Figure 5, below. Figure 5. RT-ANA Connections to RT3000 The pin assignments for the connectors on the RT-ANA are given in the following tables.
