I am wondering if there is an answer for experienced users of Leica 1100 series instruments. I have a GEV187 cable that orks with my data collector but it doesn't work with my Parini?ÿ bluetooth . The Bluetooth will work with a GEV186 and a GK1 as well as the data collector.?ÿ Any wiring diagrams that may explain this issue or other suggestions are welcomed Jim Frame. HAPPY NEW YEAR TO ALL AND TO ALL A GOOD NIGHT.?ÿ
As I recall, the GEV187 has a 9-pin dsub connector for serial I/O, while the GEV186 is all-Lemo.?ÿ What are you plugging into what?
I don't have a GEV187, but I've attached the GEV186 pinout diagram that I made years ago.
It may be as simple as RX/TX reversal.?ÿ ?ÿDid you try a null modem adapter in front of the parini?
I am trying to connect a parani sd1000 bluetooth transmitter to my 1102.?ÿ The GEV186 with a GK1 works the GEV186 cable and I am able to connect both my Archer2 data collector and the bluetooth with this cabling scheme. I have purchased a GEV187 that has a 9 pin serial on one end instead of have 3 lemo connectors. The GEV 187 works with the archer 2 but not the bluetooth and I am trying to figure out why.?ÿ thanks for your help?ÿ
Hello Jim, I'm trying to know the wiring of the GEV160 cable. I am interested to understand how the 8 pins of the Lemo part (male) are connected to the RS232 9 pins female.
Do you know where I can find this pattern?
Thanks
The GEV187 is designed to allow you to connect an instrument to a PC and a red brick battery at the same time, so you can upload firmware etc from the PC without the battery running flat. The 1100 is (still) my favourite instrument, but the processors in them are basically two cups with a bit of string between them. Uploading firmware takes a long time. You shouldn't risk doing it with the smaller batteries.
If you going to use the GEV187 to run a Parani, then you need to sort out your power supply.
Because the GEV187 gives you:
@ the instrument end, you have power (coming into the instrument), common ground, RX (RS232 receive) and TX (RS232 transmit). 4 wires. The fifth pin is a dead end on the board inside the instrument.
@ the DB9 serial plug you have common ground, RX?ÿ and TX . 3 wires.
However, the Parani has the option of having power coming into it via the DB9 (pin 9). So your first problem will be power. If you run power to the Parani externally (via its own battery or via the DC port on the side) then you'll be fine. If not, then the GEV 187 will not work for you because the Parani is not getting any power via the DB9.
If you are getting power from somewhere other than the DB9, then you can really only have a null modem issue (RX to TX and TX to RX instead of RX to RX and TX to TX) or a baud rate issue. If I remember correctly, the 1100 will send data at a speed of up to 19200, so your Parani must be set to (at least) the same speed. I set mine to the same speed.
Does the Parani turn on when it is connected to the GEV187? If yes, switch the 1100 to RCS mode and press a few buttons. The "RS232-Tx/Rx" LED on the Parani should light up each time you press a button (you don't need to pair the Parani yet). If it doesn't, then reverse the RX/TX wires/pins.
You can buy DB9 null modem adapters on eBay.
The GEV186 is a very different beast. It has power coming into it from the Lemo 1B plug (from the big battery) but outputs power (12V) from both of the two Lemo 0B plugs (to power the instrument and the TCPS26B radio modem).
If the GEV187 outputted power via the DB9 (which is 12 volts from the big battery) then people might start frying components in their PCs when they connect it.
