PC/104


 
Sealevel PC/104 I/O Solutions

Designed to meet the core needs of PC/104 applications requiring high reliability, small size, and long-term availability, Sealevel PC/104 modules offer easy serial, digital, and analog expansion for the PC/104 stack.

All Sealevel PC/104 modules are available in extended temperature versions (-40 - +85C). Call for pricing.

 

 

SIO-104

PC/104 RS-232 Serial Interface Module

 

The 3551 PC/104 serial interface provides one

RS-232 port capable of data rates to 460.8K bps.

The board implements all modem control signals

for maximum compatibility with a wide range of

peripherals. The 3551 utilizes a 16C850 UART to

provide 128-byte Tx/Rx FIFOs for maximum

reliability in data intensive applications. Ordering

options allow the choice of UARTs for custom

baud rates and 9-bit protocols. Sealevel's

SeaCOM software utilities make installation and

operation easy.

 

 

 

 

 

 

ULTRA SIO-104

PC/104 RS-422/485 Serial Interface Module

 

The 3550 PC/104 serial interface provides one

serial port configurable for RS-422 or RS-485.

The board is capable of data rates to 460.8K bps

and automatically handles RS-485 transmitter

enable/disable. The 3550 utilizes a 16C850 UART

to provide 128-byte Tx/Rx FIFOs for maximum

reliability in data intensive applications. Ordering

options allow the choice of UARTs for custom

baud rates and 9-bit protocols. Sealevel's

SeaCOM software utilities make installation and

operation easy.

 

 

 

 

 

SIO.104+2.PCI

PC/104 RS-232/422/485 Serial Interface Module

 

The 3502 PC/104 serial interface provides two

serial ports, each individually configurable for RS-

232, RS-422, or RS-485. The board is capable of

data rates to 460.8K bps and automatically

handles RS-485 transmitter enable/disable. The

3502 utilizes 16C850 UARTs to provide 128-byte

Tx/Rx FIFOs for maximum reliability in data

intensive applications. Ordering options allow the

choice of UARTs for custom baud rates and 9-bit

protocols. Sealevel's SeaCOM software utilities

make installation and operation easy.

 

 

 

 

C4-104.ULTRA

PC/104 RS-232/422/485 Serial Interface Module

 

The 3540 is the first PC/104 serial interface

module to provide four software-selectable RS-

232/422/485 ports. RS-232, RS-422, or RS-485

mode may be selected independently via

software command for each of the four ports,

eliminating the need for setting jumpers or DIP

switches. The board is designed using the

XR16C864 UART, which provides a 128-byte

FIFO, 8 times larger than boards designed with

16C550 compatible parts. The larger buffers allow

error free operation even in high-speed

applications. In RS-485 mode the C4-104.ULTRA

offers automatic control of the RS-485 driver

enable for trouble free network master arbitration. Additionally, the

C4-104.ULTRA allows RS-485 network termination, critical to robust multi-drop

communication, to be selectively added to the circuit via a simple software command.
