Selects the accessory cable configuration as it applies to the GPIO-3 (General-Purpose Input / Output) and the GPIO-4 pins on the "J700" connector of the Mobile radio's Transceiver Interconnect Board (TIB). DotGreen.png "J700" is also referred to as the (data-only) GCAI (Global Common Accessory Interface) connector or the MMP (Mobile Microphone Port). This selection applies on a radio-wide basis.

DEFINITIONS:

4-Wire RS-232

In addition to the standard RS-232 data lines (TXD and RXD), the GPIO-3 and GPIO-4 pins on the TIB's "J700" connector provide the accessory cable with access to the two RS-232 hardware flow control lines (RTS and CTS).

DotGreen.png This is the radio's default configuration.

2-Wire RS-232 with PTT and HUB

Only 2-wire RS-232 (the TXD and RXD data lines) is available on the radio. The GPIO-3 pin on the TIB's "J700" connector is configured for Push-to-Talk (PTT), and the GPIO-4 pin is configured for Hang-Up Box (HUB) functionality on the accessory cable.

DotYellow.png In this configuration, the RS-232 hardware flow control lines (RTS and CTS) are not supported on the "J700" connector or the 25-pin “J600” connector of the TIB, or on "J2", the radio's rear MAP (Mobile Accessory Port).
