E2/E2 Lite
2. Designing the User System
2.1
Connecting the E2/E2 Lite with the User System
To connect the E2/E2 Lite, a connector for the user system interface cable must be mounted on the user
system.
When designing the user system, read this section of this manual and the hardware manual for the MCUs.
2.2
Installing the Connector on the User System
Table 2.1 and Table 2.2 list the recommended connectors and user system interface cables for the E2/E2
Lite, respectively.
Table 2.1
Recommended Connectors
Connector
20-pin (1.27-mm pin
pitch) connector
10-pin (1.27-mm pin
pitch) connector
10-pin (1.27-mm pin
pitch) connector
Note: When using a connector without a guide marking (keying-shroud type), take care with regard to the direction for
insertion of the cable.
Table 2.2
User System Interface Cables
Cable Type
20-pin to 20-pin cable*
(for the 20-pin (1.27-mm pin pitch) connector)
20-pin to 10-pin cable
(for the 20-pin (1.27-mm pin pitch) connector)
Note: The 20-pin to 20-pin cable can be connected to the guideless 10-pin (1.27-mm pin pitch) connector; when doing
so, however, check the pin assignments and take care with regard to the direction for insertion of the cable.
Only connect the E2/E2 Lite after confirming that there are no mismatches of alignment on the user system
port connector. Incorrect connection will result in the host machine, the E2/E2 Lite, and the user system
emitting smoke or catching fire.
