CloudLink 5G as a transparent cellular modem supports traditional RS232 interface.
Figure 6.1 - Serial Communication Connector – RS232
Pin# Name Description I/O Voltage Levels
1 RS232 Rx RS232 Mode: Receiver Line 1
+/- 10V (max)
2 RS232 Tx RS232 Mode: Transmit Line 0
+/- 3.7V (Min)
+/- 4V (Typ)
3 GND GND GND
Note: Configuration must be done using serial communication (RS232 interface) through the
corresponding configuration port (P6). The maximum baud rate for RS232 interface is 115200
bps.
Warning: Older RS232 standards have a voltage level of +/- 18V. Using this voltage level can
damage the CloudLink 5G Modem.
