Software version Authentication Device name Adapter address Target adapter address COM port setting Factory default setting ⑥. Set up serial port. ⑦. Setup RF connection. ⑧. After completing the setting, be sure to execute ‘X’ command and save, and then the Mode Switch to ‘Active’. ■ Reference: If you enter ‘?’, the list for all commands is displayed, and if ‘?’, how to use the requested command is displayed. All commands should be typed with capital letter.

②. Type ‘1’ to change a stop bit to 2 bits.. ■ Example of Parity bit setting (None -> Even) ①. Type ‘P’. ②. Type ‘2’ to change to even parity. 3) RF Connection setting This is necessary only if you communicate with other manufacturer’s Bluetooth devices instead of the WCS-232 or change the initial settings. ■ Example of Target Address setting (00:00:00:00:00:00 -> 00:02:78:01:EF:BC) ①. Type ‘A’. ②. Type the target address to be changed. You have to enter the 12-digit hexadecimal address.

② Type ‘M’. ③. Type ‘1’. ■ Example of device name setting ①. Type ‘N’. ②. Enter the desire device name and press ‘Enter’ key (however, up to 30 alphanumeric characters possible). ■ Example of setting PIN ①. Type ‘E’. ② Enter the desire PIN value and press ‘Enter’ key. (However, up to 16 alphanumeric characters possible) ■ Example of setting low power mode ①. Enter ‘K.’ If you want to set up a low power mode, enter ‘E’, or if not, enter ‘D’.

■ Display Device Information ①. Type ‘V’. ②. All current information is displayed. At this time, verify that the values are identical to the ones you have once set. ■ WCS-232 Pair Setting WCS-232 always perform 1:1 communication in pairs. The following example showing how to set up the destination WCS-232 address. ①. Set baud rate, data bits, parity and stop bit to 9600-8-NONE-1 at Hyper Terminal. ②. Connect one of WCS-232s to your PC serial port and put ‘Mode Switch’ to Setup Mode.

Enter BD_ADDR. ④. Save the setting using ‘X’ command and then put the ‘Mode Switch’ to ‘Active’. ⑥. Apply stage ②~④ procedures to the target WCS-232, and set the opposite BD_ADDR of two WCS-232 devices to TARGET_ADDR. Appendix-A : Wait for user command mode The Wait mode that waits for a command by a user performs search and connection of accessories. The correspondent adapter shall be set up in Wait mode. ■ Search It searches Bluetooth devices connected and serviced in the same coverage.

D.2.2. Response Message AT response messages from the WCS-232 may affect the host system unexpectedly. Do not use WCS-232 If your applications cannot allow for this wireless time delay. D.3. Transmission Delay D.3.1. RF Processing Delay It takes 30msec approximately for a WCS-232 to complete a data transmission to the other Bluetooth device. This time delay cannot be reduced and may enlarge as the RF transmission environment becomes worse.
