4.4.2 UART2 interface
The UART2 supports R-UIM interface.
Table 4-4 UART2 Interface Pinouts
NAME
DESCRIPTION PIN NUMBER CHARACTERISTIC
DP_RXD2
Receive Data 20 Input data to the module
DP_TXD2 Transmit Data 21 Output data from the module
DP_CTS2/ Clear to Send 22 Clear to send from the host
DP_RFR2/ Ready for Receive 23 Ready for receive to the host
GND Signal Ground 11, 12 Signal ground
* Leave unused Pins open.
If a customer wants to use R-UIM card, UART2 can’t be used as UART.
4.4.3 UART3 interface
The UART3 is used to monitor and diagnose the status of the DTG2000-Dual V2.0. It is strongly
recommended for the user to have the following UART3 pins connected to an extra connector or to test
points, in order to easily troubleshoot any problems with the module.
