RS232 to TTL or CMOS low voltage serial interface.  The adapter plugs into a Pc comport, and appears like a serial interface to the user.  By rstoring one jumper, the adapter can also be used to connect to a RS422 4-wire interface or an RS485 2-wire interface.

Features

• Made in the USA - Comprehensive User's Manual included
• RoHS Compliant - Lead Free parts, PCB and construction

TTL / CMOS

• Plugs into DB-9 PC serial comport
• Input-Output CMOS/TTL protected (-7v to +12v)
• Baud rates to 921.6 Kbaud (tested to 1.1Mbps)
• Powered from serial port for most installations.
• Latest Surface Mount Technology (SMT) for low power and small size
• Usable for RS422 and RS485 with one jumper restored
• Designed and Manufactured in the USA

RS-232

• Meets or beats EIA-232 signal level specifications
• Pin compatible to a PC comport (DTE, female DB-9)
• RS232 output is short circuit proof

Optional RS-422/RS-485

• Meets or beats EIA-485 and EIA-422 signal level specifications
• RS422 SMPTE pin compatible (female DB-9)
• Transmit data at distances up to 4,000 feet (1,219.2 m)
• 4 wire full duplex or 2 wire half duplex operation
• Operate in multidrop (RS-485) or multipoint (RS-422) applications
• Selectable data loopback or echo suppression
• Choice of fixed or auto controlled transmit and receive (AutoXmit)
• Terminate resistor jumper (120 ohms) on input

Unique/Advanced Features

Unique to ANC-6090C:

• Run TTL/CMOS I/O over one wire using controlled transmit feature
• Usable for RS422 and RS485 by restored solder jumper
• External power maybe applied to the adapter through the TTL/CMOS DB-9 connector

Advanced Features:

• Pads on PCB to solder attach an external power source (prewired ANC-6090CX version available)

Hardware Specifications

Mechanical/Connectors

• Adapter Dimensions: 2.4" x 1.3" x 0.7" (61mm x 33mm x 18mm)
• Female DB9 plugs into PC RS-232 serial comport
• Female DB9 for TTL/CMOS interfacing

Electrical Specifications

• Voltage: +3v from comport or +3v to +12v externally applied DC
• Current: 6ma for port powered applications
• RS-485/422 output drive: short proof output
• RS232 output drive: short proof output, under worse case conditions, 5v switching to exceed 3v EIA RS232 specification

Signal Level Definition

Software

The converter operates without installing any additional drivers. The system software that runs the PC comport drives the ANC-6090 adapter. Because the adapter just converts RS-232C to and from RS-485/422 or TTL/CMOS level signals, no software modifications are required to operate the adapter with off-the-shelf applications that use the serial communications port.
