Installation and maintenance

Communication with MoCon using HTerm

Julian Ziegleder uses HTerm (but you can also use hyperterminal):

• Connect the serial cable (9600 baud, 8bits, 1 stop, no parity)
• set Newline at LF
• Input control-> send on enter CR

How to set IP

• Get IP address 1 31 0. It was set to 172.20.239.61
• Set IP address to the desired IP (e.g. 192.168.18.4): 1 30 0 192 168 18 4
• Get IP mask and gateway with 1 33 0 and 1 35 0. They were set to 255.255.255.255
• New values are valid after a reset 1 8 0
• When serial connection is no more needed it must be disabled using . See User Guide p. 21 (Communication mode and card address) and ask JZ.

Communication with MoCon using OAA IDL library

This can be useful for troubleshooting and to discriminate between SW and HW issues.

The library is installed in WorkStation1 in ~/idl/usr_lib/mocon that is already in the IDL path. Identify the cardno (=1 in the Lgsw case) and the motorno (between 1 and 8), depending on the port used to connect the device to the MoCon. See for example AdaptorBox for a list about how the motors and the dark wheel of LgswUnit are connected.

Start IDL and see the example below where cardno=1 and motorno=1. Typically you want to use genericCmd(cardno, code, motorno, param) and refer to the MoCon Programmers Guide

How to adjust current

Current for each channel of the card has to be adjusted.

Please check first the current of each channel before you connect it to the motor.
Each channel has a measuring point and a potentiometer. Please set each channel to 0,286V if the motor is not running. 
If the motor is running you should measure 0,340V -> 340mA.

On 23 March 2012 I did it on the old card SMD8 S/N17. On 11 October 2012 It is repeated on SMD8 S/N21
