how to install Digi Modem Adapter

Installing the Digi Modem Adapter is straightforward and designed for quick setup with minimal disruption. Before you begin, power down the devices involved to prevent any electrical issues during connection. Follow these simple steps to establish a stable Ethernet-to-serial bridge:

  • Identify the ports: locate the RJ-45 network port on your device or switch and the DB-9 serial port on the target equipment. Confirm that the devices you’re connecting can communicate over a serial interface via the adapter.
  • Connect the RJ-45 side: insert the RJ-45 connector of the Digi Modem Adapter into the corresponding network port on the device or network equipment. Ensure the connection is snug and oriented correctly to avoid loose connections that could cause intermittent data loss.
  • Attach the DB-9 Male end: plug the 9-pin DB-9 Male connector into the serial port of the device you’re interfacing with. If a gender or pinout mismatch is suspected, consult the device’s documentation to confirm the appropriate serial configuration and ensure the adapter pins align properly.
  • Verify alignment and power up: double-check that both connections are secure. Restore power to the devices, and monitor for link indicators or status LEDs that confirm a successful connection. If your system requires configuration, set the appropriate baud rate, parity, data bits, and stop bits according to your serial device’s specifications.
  • Test data transmission: run a simple test to verify data flow between the Ethernet-connected device and the serial peripheral. Check for successful command responses, data integrity, and any error indicators. If issues arise, reseat the connectors and recheck settings, as a fresh connection often resolves intermittent problems.

Note: The Digi Modem Adapter is a passive adapter, meaning it does not require drivers. It simply provides the physical bridge between RJ-45 and DB-9 interfaces, so the setup relies on proper port configuration on the connected devices. For critical deployments, keep spare adapters on hand from the 8-pack to minimize downtime caused by a loose connection or damaged connector.

Comfortable, reliable, and super convenient for everyday use
Size: Size 3, Unit Count: 136, Size: Size 3, Unit Count: 136
I’ve been using these diapers for a while now and they’ve honestly made things much easier for us. One of my favorite features is the pull-up (pant-style) design. It’s especially helpful when the baby is active and doesn’t want to stay still during changes. Compared to traditional diapers, these feel much more convenient and quicker to put on. In terms of comfort, they are very soft and lightweight, and my baby seems comfortable wearing them for long periods. I also really appreciate that they are unscented — there’s no strong or artificial smell, which is something I’ve noticed with other brands. Absorbency has been great so far. They don’t feel overly wet even after extended use and have held up through the entire night without leaks, which is a huge plus. The inside material stays evenly distributed and doesn’t become lumpy, even after several hours. Pros: Easy pull-up design (great for active babies) Soft, lightweight, and comfortable No strong scent or odor Good absorbency without feeling too wet Reliable overnight protection Holds shape well (no clumping) Cons: Slightly different from traditional diapers, may take a bit of getting used to Overall, these have been a very reliable choice for us. I’ve already reordered them multiple times, and they’ve consistently performed well. I would definitely recommend them to other parents looking for something comfortable, convenient, and dependable.

Leak Proof!
Size: Size 5, Unit Count: 56
These are great for overnights! They do not like and you don’t have to worry about not putting it in correctly as you struggle with a rolling alligator. I’m a fan because they do not leak like others while the kids sleep.

Great for Sensitive Skin
Size: Size 5, Unit Count: 128
I've tried other diapers and I keep coming back to Huggies as they are the only ones that don't cause irritation for my little one. Little one is 12kg and we use size 5. They are very roomy but still snug enough around the waist. I'm amazed at how absorbent and soft they are. Although there are "cheaper" diapers out there, they don't hold as much and aren't as comfortable.

Good, but not better than Pampers 360.
Size: Size 5, Unit Count: 100, Size: Size 5, Unit Count: 100
We use Pampers 360’s for our 18 month old, but we decided to try out Huggies 360’s to check if they were better Huggies 360 differ from Pampers 360 in size. These Huggies are huge compared to Pampers, they fit true to size but are puffy and take up more space in the diaper bag and the diaper drawer. My toddler prefers to run around wearing only a diaper. Huggies are less durable than Pampers, they will fray and pill more with the friction of surfaces. They perform the same as the Pampers, we didn’t experience any leaks. They are also similar is softness to Pampers. The elastic at the sides also seems tighter than Pampers. The main reason we won’t be switching to Huggies 360 is that the absorbent panel in the front is wider and less flexible so more difficult to get into a comfortable position for my son’s anatomy. They do function well as diapers, they just aren’t for us.
