This multi application serial adapter provides a simple way to connect a variety of devices to a computer using a PC comport.  The user can jumper set the adapter to interface as an RS422 4-wire interface, RS485 2-wire interface or TTL / CMOS low voltage interface.
The adapter plugs into a Pc comport, and appears like a serial interface to the user. 

Features

• Internal Adapter bracket mounting to PC

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

RS-232

• Meets or beats EIA-232 signal level specifications
• Pin compatible to a PC comport (DTE, female DB-9)

TTL / CMOS

• Input / Output jumper for RS232 to TTL/CMOS serial interfacing
• Input voltage protected ( -7v to +12v )
• Run TTL/CMOS over one wire with controlled transmit
• ANC-6090C converter preset for TTL / CMOS operation

Unique/Advanced Features

Unique to ANC-6090:

• External power maybe applied to the adapter through the RS422 DB-9 connector

Advanced Features:

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

Hardware Specifications

Mechanical/Connectors

• Adapter case size: 2.4" X 1.3" X 0.7" (LWH)
• Female DB9 plugs into PC RS-232 serial comport
• Female DB9 for SMPTE RS485/422 and TTL interfacing

Electrical Specifications

• Voltage: +3v from comport or +3v to +12v externally applied DC
• Current: 6ma for port powered applications, 100 ma for long and/or terminated cable applications externally powered
• RS-485/422 output drive: short proof output, non-terminated operation to 150 feet, terminated operation to 4,000 feet.
• RS232 output drive: short proof output, under worse case conditions, 5v switching to exceed 3v EIA RS232 specification

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.
