Technical Description
Technical Description
The ACB-232.LPCI utilizes the Zilog 85230 Enhanced Serial Communications Controller (ESCC). This chip
features programmable baud rate, data format and interrupt control. Refer to the ESCC Users Manual for details on
programming the 85230 ESCC chip.
Features
• One channel of synchronous or asynchronous communications using the Zilog Z85230 chip
• EIA/TIA-232 Signals supported TD, RD, CTS, RTS, DCD, DSR, DTR, TXC, RXC, TSET, RI
• Programmable options for Transmit clock as input or output
• Software programmable baud rate
Internal Baud Rate Generator
The baud rate of the ESCC is programmed under software control. The standard oscillator supplied with the board is
7.3728 MHz. However, other oscillator values can be substituted to achieve different baud rates.

Technical Note: Please terminate any control signals that are not going to be used. The most common way to do this
is connect RTS to CTS and RI. Also, con nect DCD to DTR and DSR. Terminating these pins, if no t used, will help
insure you get the best performance from your adapter.

Appendix A - Troubleshooting
Appendix A - T roubleshooting
The Sealevel Software is supplied with the Sealevel Systems adapter and will be used in the troubleshooting
procedures. Using this software and following these simple steps can eliminate most common problems without the
need to call Technical Support.
1. Identify all I/O adapters currently installed in your system. This includes the on-board serial ports, controller
cards, sound cards etc. The I/O addresses used by these adapters, as well as the IRQ (if any) should be
identified.
2. Make sure the Sealevel Systems adapter is securely installed in a PCI slot.
3. Use the supplied software and User Manual to verify that the Sealevel Systems adapter is configured correctly.
4. Windows users can use the installed programs in the SeaMAC folder to verify operation.

Appendix C - Electrical Interface
Appendix C - Electrical Interface
RS-232 Or EIA/TIA-232
Quite possibly the most widely used communication standard is RS-232. This implementation has been defined and
revised several times and is often referred to as RS-232 or EIA/TIA-232. It is defined by the EIA as the Interface
between Data Terminal Equipment and Data Circuit- Terminating Equipment Employing Serial Binary Data
Interchange. The mechanical implementation of RS-232 is on a 25-pin D sub connector. RS-232 is capable of
operating at data rates up to 20 Kbps at distances less than 50 ft. The absolute maximum data rate may vary due to
line conditions and cable lengths. RS-232 often operates at 38.4 Kbps over very short distances. The voltage levels
defined by RS-232 range from -12 to +12 volts. RS-232 is a single ended or unbalanced interface, meaning that a
single electrical signal is compared to a common signal (ground) to determine binary logic states. A voltage of +12
volts (usually +3 to +10 volts) represents a binary 0 (space) and -12 volts (-3 to -10 volts) denotes a binary 1 (mark).
The RS-232 and the EIA/TIA-574 specification defines two type of interface circuits, Data Terminal Equipment
(DTE) and Data Circuit-Terminating Equipment (DCE). The Sealevel Systems adapter is a DTE interface.
