TCP-232 TCP-232


RS-232 Port

The RS-232 port supports asynchronous data rates of 1200, 2400, 9600, and 19,200 baud. Data format is always 8 bit, no parity, with one stop bit. The TCP-232A provides four handshake and status signals:

The handshake signals can be connected directly to the like-named signals of an IBM-PC’s serial port.

Ethernet Port

The Ethernet port supports TCP socket services for a single socket. The TCP-232A will reject requests for more than one simultaneous connection. The TCP-232A also supports ARP (Address Resolution Protocol) and all ICMP messages (Internet Control Message Protocol, includes PING). Four LEDs show network activity (Tx and Rx), collision detect and link good (for 10Base-T).


The TCP-232A has an 8 position DIP switch that controls the following: Baud rate, Handshake enable, Handshake type (hardware or XON/XOFF), remote reset output enable, Ethernet interface select (10Base-T or AUI), and TCP setup enable. With TCP setup enabled, the serial port can be used to set the various TCP operating parameters, including IP address and TCP socket number. These TCP parameters are stored in NVRAM.




PC/104 form factor: 3.775 inches by 3.550 inches with four mounting holes and optional 8-bit stackthrough PC/104 bus connector.


The TCP-232A is designed to be integrated into the customer’s equipment. Operating temperature range should be maintained between 0 degrees Celsius and 70 degrees Celsius, non-condensing.
