The Definitive Guide to Pepwave MAX Serial Ports


Some Pepwave products come with serial ports, all of them are RS232 DTE. Here are the different form factors you will encounter, and how to connect them:

- Terminal Block

Found on the MAX Transit, BR1 ENT, HD2 Mini, and BR1 Slim. These operate in DTE mode, with pinouts as printed on the router.

- Serial Port Adapter

An optional Port adapter (ACW-411) is available for the BR1 Mini. This is a standard RJ45 serial connector operating in DTE mode, with the pinouts as follows:

Flow Control Requirements

Hardware Flow Control Software Flow Control
BR1 Mini: No No
Other MAX Routers: Yes No

For Software Flow Control, both ends must be using the same configuration. Therefore, the remote end device should also turn off Software Flow Control.

Is it possible to use serial port (RS232) on BR1 ENT, MAX Transit as a source of informations? Not for OOBM, but for communications with cars?

Thank you for your effort.


What would be the standard pinout to connect a regular ethernet cable to a MAX BR1 ENT then? If the other end is the standard white/orange, orange, white/green, blue, white/blue, green, white/brown, brown sequence, what wires would I connect to the terminal block for TX, RX, RTS, and CTS?


Basically you need to understand the other end device console port pin in/out inorder to decide how to connect the cable. Below are one of the example for Cisco Router.
