Lacerta MGEN II - no ST-4 output

[geoland]

Hi.

I recently purchased a Lacerta MGEN II standalone auto-guider and used it once out of the box - it worked well.

Last night, second time out, no guiding - the problem, no ST-4 output.

The camera and handbox auto-guiding function behaves normally (factory settings) and 'all' other indications suggest there is nothing wrong with that part of the system. The ST-4 cable is not broken - resistance measured at both ends. However, a voltmeter indicates 0V at the ST-4 cable ends during auto-guiding - no pulse to the motors.

Before I go down the warranty path, I am concerned that I have switched something off - the unit is not in emulation mode and manual mode produces no output.

I cannot think of a need to explicitly switch ST-4 on or off. The documentation states that the primary, default, function is auto-guiding and it worked first time out of the box. I did hook up the unit to a laptop to look at the desktop client, just exploring the various options. Coincidence or component failure? Have I inadvertantly messed with settings. If not, it's hardware.

Anyone had the same issue?

Not had any problem here, touch wood.

Have you tried another cable just in case?

Just a thought, see if the contacts in the ST4 port are ok.

Fairly certain both are OK. Won't hurt to try. 

I forgot to mention that AE is not honouring delay time. Opens the shutter immediately. ?

The only time mine messed about was when I disconnected the leads while still powered.

It would'nt play ball until I switched it on and off.

No joy, unfortunately. But a full reboot with a firmware update (same version) might do it, come to think of it.

No joy with firmware update. Problem now with vendor.
