Ethernet to RS-232 Serial Bridge
The ELK-IP232 may be used to connect any standard serial communications device to an Ethernet
network. It is able to both initiate and accept network connections. Once a network connection is made,
the remote networked device is virtually connected to the serial device on the other side of the Bridge.
Both the network device and the serial device can send and receive messages to and from each other.
• Supports both UDP and TCP protocols
• Up to 12 simultaneous TCP-IP connections
• Up to twelve (12) "Rules" may be programmed
to make outgoing connections.
• Selectable baud rate from 300 to 115200 baud
• 802.3 compliant 10/100 Mbit interface
• Software and Hardware Handshaking
• Operating Voltage: 12 Volts D.C.
• Current Draw: Approx. 135 mA
• Dimensions: 3.85” L x 1.7”W x 0.93” D
• RS-232, DB9M 9-pin serial port connection
• RJ45 8-pin Network Jack
• LED Indicators for Power, Link, and Data
• Includes: Serial Cable and 12V Supply

Supervised Remote Power Supply
The ELK-P212S is a Supervised Remote Power Supply/Battery Charger, providing 12 VDC output with
up to 2 Amps of total current. It supervises the AC Power Input as well as the rechargeable Battery, and
can report abnormal conditions back to an ELK-M1 Control over the RS-485 four (4) wire data bus. It
also features relay outputs for AC and Low Battery to allow “stand-alone” operation with other controls.
• M1 Control allows:
- Remote power reset of powered peripherals
- Data-bus supervision of AC and Battery status
• Stand-alone exibility
- Two (2) sets of DC outputs
- On-board relay to supervise battery status
- On-board relay to supervise AC status
• Master AC and Battery ON / OFF Power Switch
• Visual AC Power Indicator
• AC Input: 16.5VAC, 45VA (TRG1640 or equiv.)
• DC Output Voltage: 13.8 Volts D.C. +/- 5%
• Current Rating: 2.0 Amps
• Wattage: 30 Watts
• DC Output Protection: Auto Resetting PTC
• Rechargeable Battery Size: Max. 12 Ah
• Low Battery Cutoff Threshold: ~10 Volts.
• Load Regulation: + / - 2%
• Lifetime Limited Warranty
