BlackBox, IC478A-M-R2, Async RS232 to RS485 Interface Converter DB25 to DB25

Features:

Operates Asynchronously, Point-to-Point or Multipoint, over 2 or 4 Wires
Data Rates to 115.2 kbps
Selectable RTS-CTS Delay
Selectable High-Low Impedance
Carrier may be Continuous or "Controlled by RTS"
50 drops in a multi-point environment
Built-In Surge Protection
Both the RS-232 and the RS-485 connectors are DB25 male.
Built-in silicon avalanche diode surge protection against data loss and equipment damage from transient surges.
You can also "fine tune" impedance and "echo" characteristics for your individual application.
For configuration, the converter has a DTE/DCE slide switch and an internal 8-position DIP switch.

Technical Details

General
Cable Required	Unconditioned twisted pair between converters: 2 or 4 wires (1 or 2 pairs)
CE Approval	Yes
Data Format	Transparent
Distance (Maximum)	Between RS-232 device and converter: 50 ft. (15.2 m), but converters not directly attached will be underpowered; Between non-RS-232 device and converter: 9 mi. (14.4 km)
Enclosure	ABS plastic
Environmental Operation	Temperature: 32 to 122° F (0 to 50° C);
Hardware Flow Control Signaling	Raise DSR in response to DTR; raise CD in response to carrier; raise CTS in response to RTS (after no delay or 8-ms delay, user-selectable); carrier is either constantly on or controlled by RTS, user-selectable
Humidity	5 to 95% noncondensing
Interface	To devices: RS-232: Original pinning on DB25, DTE or DCE (user-selectable); To line: 2- or 4-wire RS-485
Operation	Transparent to 2-wire half-duplex or 4-wire full- or half-duplex
Power	From the RS-232 data and control signals
Protocol	Asynchronous
Size	2.7"H x 2.1"W x 0.8"D (6.9 x 5.3 x 2 cm)
Software Flow Control	Transparent
Speed	Transparent to 115.2 kbps
Surge Protection	Internal Silicon Avalance Diodes dissipate surges up to 600 watts per wire within 1 ms
User Controls	(1) DTE/DCE slide switch and (1) internal 8-position DIP switch for configuration
