Software Setup

The ePS is supplied with an IP address of 192.168.0.209. This address is in the space reserved for private networks.

If your PC is configured to respond to different IP addresses based to its own IP address and mask settings, then the ePS will not be recognized over the network connection by your PC.

You can change the IP address of the ePS via its serial port.

1
2 RS232 Tx
3 RS232 Rx
4
5 0v
6
7
8
9

Connect the ePS master to a host PC using the serial port, configure a terminal program (e.g. Windows Hyper Terminal) with the following settings:

Baud rate: 9600
Data: 8 bit
Parity: none
Stop: 1 bit
Flow control: none


On power up the status of the unit will be displayed:

IAM:Got AUTO-CONFIGURED IPv6 address FE80::240:9DFF:FE43:3597 on interface eth03
IAM:Got STATIC IPv4 address 10.0.0.100 on interface eth0
Network IP configured.

ePS Control Via LAN Socket Connection

The ePS can also be controlled and monitored via the LAN connection, by opening a socket on port 5000. Only one socket is available, the socket should be opened, the command sent then the socket closed to ensure that the socket is not left engaged.

Request Output State

For an output status request the connected client must send a wake up to the ePS which is 0xFF and then a control code which in this case is set to 0x01. The ePS will respond with an acknowledgement of 0xFE, and an echo of the control code. It will then send 1 byte of information for units output state.

Command

FFh – Wake Up Server
01h – Control Code – Output status req

Response
FEh – Acknowledge
01h – Control Code
Byte 1 – Output – 00=on 01=off 02=fuse fail

Operate Output

To switch an output a wake up code and a control code must be sent as before with the control code this time set to 0x02. Then a byte must be sent to describe to the unit how to switch the output 0x00 – off, 0x01 – on, 0x02 - cycle. The eMu will again acknowledge and echo the control code.

Command

FFh – Wake Up Server
02h – Control Code – Operate output
[state] - 1 = Switch Output On
0 = Switch Output Off
2 = Cycle Output

Response

FEh – Acknowledge
02h – Control Code
