Shipped to operate as an RS422 without setting any jumpers.  The ANC-6185T has additional electronics and jumpers for use with RS-485 2-wire interfacing.  Ideal for connecting a variety of devices to a computer using a PC comport.  The user can set the adapter to interface to a 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.

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 on board controlled transmit (AutoXmit)
• ANC-6090C converter preset for TTL / CMOS operation

Unique/Advanced Features

Unique to ANC-6185T:

• Pads on PCB to solder attach an external power source (prewired ANC-6185TX version available)
• External power maybe applied to the adapter through the terminal block connector

Advanced Features:

• 2-Wire RS-485 operation controlled automatically (AutoXmit) or with RTS line
• Solder pads for Transmit/Read LEDs (pre-installed ANC-6185TL version available)

Hardware Specifications

Mechanical/Connectors

• Adapter size: 2.9" x 1.3" x 0.7" (74mm x 33mm x 18mm)
• Female DB9 plugs into PC RS-232 serial comport
• 6-pin Terminal Block for fast RS422/485 and TTL/CMOS 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-6185T adapter. Because the adapter 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.
