Technical Description The ACB-MP+4.PCI utilizes the Zilog 85230 Enhanced Serial Communications Controller (ESCC) and includes a dedicated Z85230 per port. This chip features programmable baud rate, data format and interrupt control. Refer to the ESCC Users Manual, available from Zilog, for details on programming the 85230 ESCC chip.
100-Pin Connector Pin Out The ACB-MP+4.PCI has a 100-pin high-density connector and includes a cable (Item# CA339) that breaks out to four (4) DB25 male connectors. The pin outs for RS-232, RS-485, RS-530, RS-530A, and V.35 interfaces on the DB25 connectors are listed on the following pages.
Interface Selection The ACB-MP+4.PCI supports a variety of electrical interfaces. Refer to the Control and Status Register Definitions found in the Technical Description section of this manual for this bit description. There is line termination on RXD, RXC, and TXC in the following modes: RS-530, RS-530A, RS-485T, and V.35.
10.69cm Manufacturing All Sealevel Systems Printed Circuit boards are built to UL 94V0 rating and are 100% electrically tested. These printed circuit boards are solder mask over bare copper with either Electroless Nickel Immersion Gold (ENIG) or Hot Air Solder Leveled (HASL) finish.
IRQ (if any) should be identified. 4. Configure your Sealevel Systems adapter so that there is no conflict with currently installed adapters. No two adapters can occupy the same I/O address.
If possible, please have the adapter installed in a computer ready to run diagnostics. Sealevel Systems provides an FAQ section on its web site. Please refer to this to answer many common questions. This section can be found at http://www.sealevel.com/faq.asp...
(-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. RS-422 The RS-422 specification defines the electrical characteristics of balanced voltage digital interface circuits.
