Appendix–C: Trouble Shooting
D.1. No Data Transmission
D.1.1. COM Port Settings
Check whether the Baud rate of WCS-232 matches that of its host equipment.
Check whether the host equipment has a Data bit setting of 8. WCS-232 supports only 8 Data bit settings. If your
host equipment uses 7 Data bit and even or odd parity, it may work with a 8 Data bit and No parity setting. This
is valid only when both DCE devices are the WCS-232. In this case, set both WCS-232s] to 8 Data bit and No
parity. If one of DCE devices is another Bluetooth device such as Bluetooth USB dongle,7 bit data configurations
will not work.
Check whether the Parity and Stop bit of WCS-232 match those of your host equipment. WCS-232 supports No
parity, Even parity and Odd parity, 1 and 2 Stop bit configurations.
Check whether the host equipment of WCS-232 uses Hardware Flow Control. WCS-232 is initially set to Use of
Hardware Flow Control. If your host equipment does not use Hardware Flow Control, please disable the Hardware
flow control option by referring to ‘5.Operating environment setting’.
WCS-232 does not support RS-232 break signal.
D.1.2. Pin Assignment
WCS-232 is a DCE device. If your host equipment is DTE, plug WCS-232 directly to the host equipment or use
straight RS-232 cable. If your host equipment is DCE, use will need to use a cross over RS-232 cable (Null
modem cable) or a Male to Male DB9 Null Modem adapter.
D.2. Data Loss or Malfunctioning
D.2.1. Hardware Flow Control
When transmitting large amounts of data with No Hardware Flow Control, WCS-232 may clear the data buffer
unexpectedly. The possibility becomes greater as the RF transmission environment becomes worse.
