Vary the word length, stop bits, and baud
rate until good transmission is achieved.
Features include a 9-24 VDC power range, switch-selectable baud
rates from 9600 to 115.2K and LED indicators for power, transmit and receive.
The rate is $15 per hour (25 cents per minute) at 300 baud
(about 30 characters per second) and twice as much for 1200 baud
(about 120 characters per second).
Consider an application that samples an audio input at 8 kHz using a 10 bit ADC that converts the sampled audio to mu-law encoding (8 bits, used in telephone communications) and transmits this via an RS-232 serial line at 115,200 baud
, as well as processing the audio signal and driving a VU meter showing current audio level.
Tellabs and Baud
Telecom Co, Tellabs' representative in Saudi Arabia, will jointly design, install, commission, migrate, test and maintain the new network.
"If you take an (ISDN) terminal and compare it to a typical phone with a 9600 baud
modem and two phone lines, it comes out within less than $100 difference."
* A programmable baud
rate from 4,800 to 115,000 baud
Used with proprietary virtual COM port (VCP) drivers, the USB NMC provides inter-PC,COM port-based communication at up to 3M baud
CNet, San Jose, Calif., launched its CN2400, a 2400 baud
The addition of the XCRS card provides users with supplementary RS232 and RS485 multiplexed ports capable of communicating with RS232, RS422, RS485 and DH485 devices at up to 115,200 baud
