Troubleshooting
1
After connecting to the
supply, the status indicator
of PSM2001ACD doesn’t
turn on
1.
Check if the hardware connection is correct
2.
Check if the PSM2001ACD is initialized by user’s program correctly
2
After connecting to the
supply, the status indicator
of PSM2001ACD turns on,
but the PSM2001ACD
doesn’t work in RS-232
mode normally
1.
Check if the TXD of the PSM2001ACD is connected to pin 2 of DTE,
the RXD of the PSM2001ACD is connected to pin 3of DTE, and pin 5
of DTE is connected to GND
2.
Check if the baud rate of the PSM2001ACD is the same as that of
serial port of the PC
3.
Check if the serial port of the PC is connected correctly
4.
Check if pin 9 of the PSM2001ACD is connected to pin 10 of the
PSM2001ACD directly
5.
Check if the
ID of the access device configured by the
gateway
software is the same as that of the module labeled on the board
3
After connecting to the
supply, the status indicator
of PSM2001ACD turns on,
but the PSM2001ACD
doesn’t work in RS-485
mode normally
1
Check if the serial port of the PC in which the WebChipServer
TM
software is programmed has a RS-232 to RS-485 connector
2
Check if the ID of the access device configured by the gateway
software is the same as that of the module labeled on the board
3
Check if the PSM2001ACD is initialized by the user’s program
correctly
4
Check if terminal A and B of RS-485 are connected correctly
5
Check if pin 9 of PSM2001ACD is connected to pin 11 of the
PSM2001ACD directly
6
Check if the baud rate of the PSM2001ACD is the same as that of
serial port of the PC
4
After connecting to the
supply, the status indicator
of PSM2001ACD turns on,
but the PSM2001ACD
doesn’t work in Modem
mode normally
1.
Check if pin 9 of PSM2001ACD is connected to pin 10 of the
PSM2001ACD directly
2.
Check if there is dial tone on the telephone line
3.
Check if user’s program has a valid telephone number
