2 The comparison table of these 3 types of communication controller is given as follows:
3 RS-232/485/422 Communication Controller family Embedded RS-232/485/422 Controller. Write firmware for controller. Write application program for Host-PC. Can solve any problem even for I/O control or data compression or security. Need to write two programs. The most flexible solution for user Addressable RS-232/485/422 Converter. Download firmware-1 to CPU module. Write application program for Host-PC. Can solve nearly any problem even for I/O control or data security or compression. Need to write one program. The trade-off solution for user RS-232/485/422 Device Server. Download firmware-2 to CPU module. Execute P&P utility in Host -PC during the installation stage. Can solve most of problems. No need to write any software. The most easy solution for user

15 Self-Tuner ASIC Inside On All RS-485 Port • 2 -wire RS-485 ->half-duplex network -> send/receive direction control. • Self-Tuner ASIC controller ->auto detect & control the send/receive direction of RS 485 network • The 8000 family equips a Self-Tuner ASIC controller on all RS-485 ports(COM 2/3 of 841 x/881 x, 8142 & 8144). To. Com(port, sent_data); /* send one sent_char to RS-232/RS-485 /* no direction control */ while Is. Com(port); /* wait one echo_char from RS-232/RS-485 */ echo_data=Read. Com(port); /* read this echo_data */ */
16 Using HP 34401 A 1. Wire Connection of HP 34401 A to RS 232 interface of host 3. HP 34401 A initialization command: SYST: REM(0 x 0 A) command = SYST: REM(0 x 0 A) response = no response 4. read data from HP 34401 A command: READ? (0 x 0 A) command = READ? (0 x 0 A) response = -? . ? ? ? E+? ? (0 x 0 A) 2. RS-232 configuration setting of host Baud rate=9600 BPS Parity=Even Data=7 Stop bit=2
