Serial Loopback Tester



	DB25 Female and DB9 Female Wrap Plug
	Is your modem or other RS232 serial devices not working? Save time and money! CablesNMor's Serial Loopback Tester will allow you to check out your serial ports first. This tester is also known as a wrap plug. This will not work as an adapter because the wires are wrapped around. They do not go from end to end. We also carry the Parallel Loopback Plug. Please note: Testing software is not included.
