So I had an issue that a Hermes Pro/S+ router died. This is used by pharmacy software (more specifically Apotheken Software) to get order supplies from the supplier. Now of course when we asked the support company for some help, they immediately said that would be 1000 euros please. In fact they did not want to tell us the price. They just wanted to charge directly. And they did not offer any other options.
So instead i ordered a Hermes Pro/SH online from ebay. So it arrived. Cool! Then i found out that it did not have an IP written down. For anyone that may know, that means its not really easily configurable. The next way to do this was over the V24 port. This is a serial port and should connect easily to your PCs COM port. That's if u still have one:). Basically a Ethernet to 9 pin serial port cable is necessary. Now looking online, they did exist, but that meant ordering a cable and we did not really have the time for that. So a i decided to make my own. Just cut open a Ethernet cable and join it to 9 pin serial cable (USB adapter which i bought for my laptop).
So i did this following the standard that exists for Ethernet to 9 pin serial. Then i fired up putty to telnet into the router, but nothing:( my heart sank. So much time and still no solution. And the business needs this to run properly... so i head home a bit unhappy. On the way i remember one point of data i got from the sales guy. That was that the Hermes router was built from an old Cisco router. So i start googling a Cisco V24 port router. I find a page detailing the mapping for Cisco. And what do u know, its not the same as the standard that i tried before! So i do some rewiring and fire up putty again. I have never been so happy to see a login screen! This was the result:
